In some embodiments, future super-five generation mobile communication technologies (Beyond 5G, b 5G) and 6G wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning for robotic navigation, wi-Fi sensing for smart home, and radar sensing for autopilot. The sensing and communication systems are typically designed separately and occupy different frequency bands. Communication and awareness Integration (ISAC) enables sensing and Communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISACs will become a key technology in future wireless communication systems to support many important application scenarios. Typical applications of ISACs include navigation and obstacle avoidance of autonomous vehicles, wi-Fi based indoor positioning and activity recognition, communication and sensing of unmanned aircraft, extended Reality (XR), radar and communication integration, and the like. Each application has different requirements, limitations and regulatory issues. ISACs have attracted tremendous research interest and attention in both academia and industry.

The ISAC obtains the integrated low-cost implementation of communication and perception dual functions in a mode of sharing hardware equipment and defining functions by software, and is mainly characterized by unifying and simplifying the architecture, reconstructing and expanding the functions, improving the efficiency and reducing the cost. The communication perception integration has the advantages of reducing equipment cost and size, improving spectrum utilization rate and improving system performance.

Currently, a scenario of typical communication awareness integration expected to be achieved by performing technology upgrade according to a 5G communication system architecture is shown in table 1 below.

Table 1:

In some embodiments, depending on the difference between the sense signal transmitting node and the receiving node, 6 sense links may be included, but are not limited to those shown in fig. 2 a. It should be noted that, in fig. 2a, each sensing link is illustrated by using one transmitting node and one receiving node, in an actual system, different sensing links may be selected according to different sensing requirements, one or more transmitting nodes and one or more receiving nodes of each sensing link may be provided, and the actual sensing system may include a plurality of different sensing links. And the perceived target in fig. 2a takes a person and a car as examples, and the perceived target of an actual scene will be richer assuming that neither the person nor the car carries or installs the signal receiving/transmitting device.

Perception link 1, base station self-receiving perception. In the mode, the base station transmits a sensing signal and obtains a sensing result by receiving an echo of the sensing signal;

and a perception link 2, namely the air interface perception between the base stations. In this manner, the base station 2 receives the sensing signal transmitted by the base station 1, and obtains a sensing result.

And a perception link 3, namely uplink air interface perception. In the mode, the base station receives the sensing signal sent by the terminal, and a sensing result is obtained.

And a perception link 4, namely downlink air interface perception. In the mode, the terminal receives the sensing signal sent by the base station, and a sensing result is obtained.

And a perception link 5, namely the terminal spontaneously self-receives perception. In the mode, the terminal sends a sensing signal and obtains a sensing result by receiving an echo of the sensing signal.

Perception link 6. Inter-terminal side link (Sidelink) perception. For example, the terminal 2 receives the sensing signal transmitted by the terminal 1 to obtain a sensing result, or the terminal 1 receives the sensing signal transmitted by the terminal 2 to obtain a sensing result.

It should be noted that, in fig. 2a, each sensing mode is taken as an example of a sensing signal transmitter and a sensing signal receiver, in a practical system, one or more different sensing modes may be selected according to different sensing cases and sensing requirements, and one or more transmitters and receivers of each sensing mode may be provided. The perceived target in fig. 2a takes a person and a car as examples, and the perceived target of an actual scene will be richer assuming that neither the person nor the car carries or installs the signal receiving/transmitting device.

Among the 6 basic sensing modes shown in fig. 2a, the transmitter and the receiver of the sensing signal belong to different devices in 4 sensing modes of inter-base station air interface sensing, uplink air interface sensing, downlink air interface sensing, inter-terminal side link sensing and the like, that is, the 4 sensing modes are double-station sensing. And the transmitter and the receiver of the sensing signal belong to the same equipment in 2 sensing modes of self-receiving sensing of the base station, self-receiving sensing of the terminal and the like, namely, the 2 sensing modes are single-station sensing.

Where dual-station perception does not require the device to have full duplex capability and signal propagation characteristics are substantially the same as in existing communication systems. Therefore, the dual-station perception can fully follow the hardware and signal design in the existing communication system, so that the integrated design of communication and perception can be truly realized at lower cost. In addition, the dual-station sensing, especially the uplink air interface sensing or the downlink air interface sensing, can flexibly select the terminal equipment for executing sensing signal transmission or receiving. If a terminal device closer to the sensing target is selected, the signal propagation distance from the sensing target to the terminal is shorter, so that lower signal propagation path loss can be obtained, and finally, the gain of the sensing signal power is brought. Based on the advantages, the double-station perception mode is always one hot spot in the general sense integrated research.

However, the dual-station sensing mode also presents a significant challenge, namely, the problem of time-frequency asynchronization between the transmitter and receiver of the sensing signal. The transmitter and receiver of the sense signal employ frequency sources in the respective devices to generate local oscillator signals and clock signals for transmission and reception of the sense signal. The difference in local oscillator signal clock signals between transceivers causes timing drift. As shown in fig. 2b, the timing offset includes two parts, a timing start point offset (indicated by τ _strat in fig. 2 b) and a timing drift (indicated by Δτ ₁、Δτ₂、Δτ₃ in fig. 2b, etc.). The timing starting point deviation is mainly caused by the integral deviation between the receiver clock and the transmitter clock of the sensing signal, and the effect is that the delay spectrum is integrally deviated. The timing drift is caused by the difference in clock period between the receiver clock and the transmitter clock of the sense signal, and the timing drift over each OFDM symbol varies over time.

The following describes in detail a method, an apparatus, and a device for determining a state according to embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a flowchart of a state determining method according to an embodiment of the present application, as shown in fig. 3, including the following steps:

Step 301, a first device receives a first signal sent by a second device, where the first signal is used for sensing measurement.

The first device may be a terminal or a network side device, and the second device may be a terminal or a network side device.

The first signal may be referred to as a sense signal.

Step 302, the first device judges the state between the first device and the second device based on the first signal, wherein the state between the first device and the second device is an LOS state or an NLOS state;

The above-mentioned determination of the state between the first device and the second device based on the first signal may be a determination of the state between the first device and the second device based on measurement of some or all symbols of the first signal, specifically a determination of whether the state between the first device and the second device is an LOS state or an NLOS state. For example, the first signal includes M symbols in the time domain, and the first device determines whether the first device and the second device are in LOS state or NLOS state based on the measurement of M0 OFDM symbols after receiving M0 OFDM symbols of the first signal, wherein 1≤M0≤M.

In the embodiment of the present application, the symbol may refer to an OFDM symbol.

In some embodiments, the determination of whether the first device and the second device are in the LOS state or the NLOS state may be based on the delay profile of the first signal, for example, if the LOS path exists in the delay profile, the determination of whether the first device and the second device are in the LOS state is determined, and otherwise, the determination of the first device and the second device is determined to be the NLOS state. In one embodiment, the first device may determine, based on a delay profile of the first signal, by combining features of LOS paths, where typically a path with the strongest power in the LOS path delay profile and a delay value is the smallest in delay values corresponding to local peaks of all delay profiles, and may determine, according to the feature, whether an LOS path exists, where the LOS path is an LOS state, and otherwise is an NLOS state. In another embodiment, the first device inputs the delay profile of the first signal into an artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) model, and the AI model outputs a determination of whether there is an LOS path, where the LOS path is an LOS state, and otherwise the LOS path is an NLOS state.

The second signal may be a signal dedicated to round trip measurement, or the second signal may be a reference signal for communication.

The reference signals for communication may be Positioning reference signals (Positioning REFERENCE SIGNAL, PRS), channel state Information reference signals (CHANNEL STATE Information REFERENCE SIGNAL CSI-RS), sounding reference signals (Sounding REFERENCE SIGNAL, SRS), and Demodulation reference signals (Demodulation REFERENCE SIGNAL, DMRS).

The activation or deactivation of the second signal may be at least one of activation or deactivation of the first device, the second device, or the third device based on a state between the first device and the second device.

The activation or deactivation of the second signal may be understood as an activation or deactivation of the transmission of the second signal, such as the second device or the third device activating the first device to transmit the second signal, i.e. the first device transmitting the second signal is activated by the second device or the third device, such as the second device or the third device deactivating the first device to transmit the second signal, i.e. the deactivation of the transmission of the second signal is indicated by the second device or the third device, in particular the first device stopping or not transmitting the second signal;

Or the activation or deactivation of the second signal may be understood as an activation or deactivation of the second signal, e.g. the first device or the third device activates the second device to receive the second signal, i.e. the second device receives the second signal, is activated by the first device or the third device, e.g. the first device or the third device deactivates the second device to receive the second signal, i.e. the deactivation of the second device receives the second signal is indicated by the first device or the third device, in particular the second device stops or does not receive the second signal;

Or the activation or deactivation of the second signal may be that the first device, the second device or the third device activates the second signal or deactivates the second signal, if the first device activates the second signal, the first device sends the second signal to the second device, if the first device deactivates the second signal, the first device stops or does not send the second signal, if the second device activates the second signal, the second device receives the second signal, if the second device deactivates the second signal, the second device stops or does not receive the second signal, if the third device activates the second signal, the third device notifies the first device to send the second signal to the second device, and if the third device deactivates the second signal, the third device notifies the first device to stop or does not send the second signal.

Wherein the round trip measurement is used to determine or suppress a timing start point offset between the first device and the second device.

In the embodiment of the application, because the activation or deactivation of the second signal is determined based on the state between the first equipment and the second equipment, the continuous transmission of the second signal can be avoided, and the transmission overhead of the equipment is saved.

In addition, in the embodiment of the application, the round trip measurement based on the first signal and the second signal can be supported, and the round trip measurement can determine or inhibit the timing starting point deviation between the first equipment and the second equipment, so that the timing starting point deviation between the first equipment and the second equipment is determined or inhibited in a perception scene, and the improvement of the perception performance is facilitated.

In some embodiments, the first device may also select a manner of determining or suppressing a timing start point deviation between the first device and the second device based on a state between the first device and the second device.

For example, in the case of an LOS state, the timing start point deviation between the first device and the second device is determined or suppressed based on the LOS path manner, and in the case of an NLOS state, the timing start point deviation between the first device and the second device is determined or suppressed based on the round trip measurement. Therefore, the LOS path mode with small cost can be adopted in the LOS state, and only round trip measurement with large cost is adopted in the NLOS state, so that the cost caused by perception can be saved.

In some embodiments, there is an LOS path in the LOS state, in which case if the location information of the first signal transceiver is known, then a true value of the signal propagation delay corresponding to the LOS path can be determined. In this case, the LOS path is the path with the smallest delay value and the strongest power. According to the above feature, the measured value of the signal propagation delay corresponding to the LOS path can be determined from the delay-doppler spectrum of the first signal, and thus, the timing start point deviation between the first device and the second device can be determined or suppressed from the actual value and the measured value of the signal propagation of the LOS path.

In some embodiments, the timing start point deviation between the receiving and transmitting ends of the sensing signal can be estimated through round trip measurement in the sense integrated system. The basic idea is that according to the radar "stop-and-go" model, the state of motion (position and velocity) of the perceived target can be considered unchanged in a short time (e.g., several milliseconds to several tens of milliseconds). For the same perception target, the two-way receiving and transmitting of the perception signals are carried out between the receiving and transmitting ends of the perception signals, the signal propagation delay corresponding to round trip measurement is the same, the absolute value of the timing starting point deviation is the same, and the signs are opposite, so that the timing starting point deviation between the first equipment and the second equipment can be determined or restrained through round trip measurement.

In addition, the round trip measurement can determine the true value of the signal propagation delay corresponding to the paths with the strongest power, and the paths with the strongest power may or may not be LOS paths. Meanwhile, the measured values of the signal propagation delays of the paths with the strongest power are also easily determined according to the time delay-Doppler spectrum, so that the influence of the timing starting point deviation between the first equipment and the second equipment can be determined or restrained.

In the embodiment of the present application, the Round Trip measurement may be a Round Trip Time (RTT) measurement, and the method for determining the true value of the signal propagation delay based on the RTT method may refer to a protocol definition manner, which is not described in detail herein.

The method provided by the embodiments of the present application is illustrated by the following examples:

Embodiment one:

In this embodiment, downlink sensing is described, where the first device is a terminal, and the second device is a base station, and specifically includes the following steps:

The terminal receives a first signal transmitted by the base station and determines the LOS/NLOS status based on measurements of part or all of the OFDM symbols of the first signal.

The first signal is used for performing a perceptual measurement, and the first signal comprises M OFDM symbols in the time domain, M being equal to or larger than 1.

After receiving M0 OFDM symbols of the first signal, the terminal judges whether the terminal and the base station are in an LOS state or an NLOS state based on measurement of the M0 OFDM symbols, wherein M0 is more than or equal to 1 and M0 is more than or equal to M.

In some embodiments, after determining the LOS/NLOS status, the terminal has the following options:

and 1, reporting first indication information to the base station by the terminal. The first indication information is used for indicating LOS/NLOS state between the terminal and the base station. For example, the first indication information includes one bit, and bit '1' represents the LOS state and bit '0' represents the NLOS state.

And 2, when the LOS/NLOS state between the terminal and the base station changes, reporting first indication information to the base station by the terminal, wherein the first indication information comprises:

If the LOS state is considered between the terminal and the base station before, reporting first indication information when the terminal judges that the NLOS state is between the terminal and the base station;

If the NLOS state is considered between the terminal and the base station, the first indication information is reported when the terminal judges that the LOS state is between the terminal and the base station.

It is noted that the LOS state or NLOS state between the default terminal and the base station may be defaulted at the beginning of the sensing measurement, for example, if the LOS state is between the default terminal and the base station, the second signal is not activated at the beginning of the sensing measurement, and if the NLOS state is between the default terminal and the base station, the second signal is activated at the beginning of the sensing measurement.

In some embodiments, after receiving the first indication information, the base station includes the following actions according to the difference of the previous states:

If the first indication information indicates that the terminal and the base station are in NLOS state, and the terminal and the base station are considered to be in LOS state before, the base station sends a third signaling to the terminal, wherein the third signaling is used for informing (or activating) the terminal to send a second signal to the base station;

If the first indication information indicates that the terminal and the base station are in the LOS state and the terminal and the base station are considered to be in the NLOS state (i.e., the second signal is in an activated state), the base station transmits fourth signaling to the terminal, the fourth signaling being used to inform the terminal to stop (or deactivate) the second signal transmitted to the base station;

if the first indication information indicates that the terminal and the base station are in an NLOS state and that the terminal and the base station were previously considered to be in an NLOS state (i.e., the second signal is in an activated state), then there is no action;

if the first indication information indicates that the terminal and the base station are in the LOS state and the terminal and the base station are previously considered to be in the LOS state, there is no action.

Wherein, the state between the previous terminal and the base station, i.e. between the terminal and the base station at the first moment in the above embodiment.

The state between the terminal and the base station considered to be in NLOS state or the state between the terminal and the base station considered to be in LOS state may be a default state when the sensing measurement is just started, or may be determined by the first indication information reported to the base station by the terminal in the previous sensing process.

In some embodiments, the third signaling and/or the fourth signaling may be DCI, MAC CE, RRC signaling, NAS signaling, or the like.

In some embodiments, the second signal is used to perform round trip measurement in conjunction with the first signal, so as to extract or suppress a timing start point deviation suffered by the first signal received by the terminal.

In some embodiments, the base station transmits configuration information of the second signal to the terminal before the terminal transmits the second signal to the base station.

Specifically, before the base station sends the first signal, the base station sends the configuration information of the first signal to the terminal, and the base station sends the configuration information of the second signal to the terminal;

or after the base station receives the first indication information, the base station sends configuration information of the second signal to the terminal and activates transmission of the second signal.

Obviously, it is preferable to transmit the configuration information of the second signal together when the base station transmits the configuration information of the first signal. Because the base station may have a relatively large end-to-end delay sending the configuration information of the second signal via RRC signaling.

Embodiment two:

The embodiment describes uplink sensing, in this embodiment, the first device is a base station, and the second device is a terminal, which specifically includes the following steps:

the base station receives the first signal transmitted by the terminal and determines the LOS/NLOS status based on measurements of some or all of the OFDM symbols of the first signal.

After receiving M0 OFDM symbols of the first signal, the base station judges whether the terminal and the base station are in an LOS state or an NLOS state based on the measurement of the M0 OFDM symbols, wherein M0 is more than or equal to 1 and M0 is more than or equal to M.

In some embodiments, after the base station determines the LOS/NLOS status between the terminal and the base station, there are the following actions:

If the base station judges that the terminal and the base station are in NLOS state and the terminal and the base station are considered to be in LOS state, the base station sends a first signaling to the terminal, and the first signaling is used for informing (or activating) the terminal to receive a second signal sent by the base station;

If the base station determines that the terminal and the base station are in the LOS state and the terminal and the base station are considered to be in the NLOS state (i.e., the second signal is in an activated state), the base station transmits a second signaling to the terminal, the second signaling being used to inform the terminal to stop (or deactivate) the reception of the second signal transmitted by the base station;

If the base station determines that the terminal and the base station are in the NLOS state and that the terminal and the base station were previously considered to be in the NLOS state (i.e., the second signal is in an activated state), then there is no action;

If the base station determines that the terminal and the base station are in the LOS state and the terminal and the base station are previously considered to be in the LOS state, there is no action.

The first signaling and/or the second signaling may be DCI, MAC CE, RRC signaling, NAS signaling, etc.

The second signal is used for configuring the first signal to execute round trip measurement and is used for extracting or suppressing the timing starting point deviation born by the first signal received by the base station.

The state considered to be NLOS between the previous terminal and the base station or the LOS state considered to be between the previous terminal and the base station may be a default state immediately after the start of the sensing measurement, or may be determined by the base station in the previous sensing process.

In some embodiments, the base station transmits configuration information for the second signal to the terminal before the base station transmits the second signal to the terminal.

The specific steps can be as follows:

before the base station transmits the first signal, the base station transmits the configuration information of the first signal to the terminal, and transmits the configuration information of the second signal to the terminal;

Embodiment III:

The embodiment describes sidelink awareness or inter-base station awareness, and specifically includes the following steps:

the first device receives the first signal transmitted by the second device and determines the LOS/NLOS status based on measurements of some or all of the OFDM symbols of the first signal.

The first signal is used for executing perception measurement, and the first signal comprises M OFDM symbols in a time domain, wherein M is more than or equal to 1.

After receiving M0 OFDM symbols of the first signal, the first device determines whether a LOS state or an NLOS state is between the first device and the second device based on measurement of the M0 OFDM symbols, wherein 1≤M0≤M.

In the case of sidelink awareness, the first device is terminal 1 and the second device is terminal 2.

In case of inter-base station perception, the first device is base station 1 and the second device is base station 2.

In some embodiments, after determining the LOS/NLOS status, the first device may have one of the following actions:

the first device reports first indication information to the awareness function network element (namely, the third device in the above embodiment), where the first indication information is used to indicate an LOS/NLOS status between the first device and the second device. For example, the first indication information includes one bit, and bit '1' represents the LOS state and bit '0' represents the NLOS state.

And 2, in the NLOS state, the first equipment reports the first indication information to the sensing function network element, and in the LOS state, the first equipment does not report the first indication information. Here, the first indication information is used to indicate that the NLOS state is between the first device and the second device.

In the case of sidelink awareness, the awareness function network element may be a base station.

In the case of inter-base station awareness, the awareness function network element may be a core network device.

In some embodiments, after receiving the first indication information, the awareness functional network element has the following action options:

If the first indication information indicates that the first device and the second device are in an NLOS state and the first device and the second device are considered to be in an LOS state, the awareness functional network element sends fifth signaling and seventh signaling to the first device and the second device respectively, wherein the fifth signaling is used for notifying (or activating) the first device to send a second signal to the second device, namely activating the first device to send the second signal, and the seventh signaling is used for activating the second device to receive the second signal;

If the first indication information indicates that the first device and the second device are in the LOS state and the first device and the second device are considered to be in the NLOS state (i.e., the second signal is in an activated state), the awareness functional network element sends sixth signaling and eighth signaling to the first device and the second device, respectively, wherein the sixth signaling is used for notifying the first device to stop (or deactivate) sending the second signal to the second device, and the eighth signaling is used for notifying the second device to stop receiving the second signal;

If the first indication information indicates that the first device and the second device are in an NLOS state and that the first device and the second device were previously considered to be in an NLOS state (i.e., the second signal is in an activated state), then no action is taken;

if the first indication information indicates that the first device and the second device are in the LOS state and the first device and the second device are considered to be in the LOS state before, no action is performed;

The second signal is used for carrying out round trip measurement in cooperation with the first signal and is used for extracting or suppressing timing starting point deviation born by the first signal received by the first equipment.

In case of sidelink awareness, at least one of the fifth signaling, the sixth signaling, the seventh signaling, and the eighth signaling may be DCI, MAC CE, RRC signaling, NAS signaling, or the like.

The state considered to be in NLOS state between the first device and the second device or in LOS state between the first device and the second device may be a default state when the sensing measurement is just started, or may be determined by the first indication information reported to the sensing function network element by the first device in the previous sensing process.

In some embodiments, the above-mentioned sensing function network element sends configuration information of the second signal to the first device and the second device before the first device sends the second signal to the second device.

The specific steps can be as follows:

before the second device sends the first signal, when the sensing function network element sends the configuration information of the first signal to the first device and the second device, the sensing function network element sends the configuration information of the second signal to the first device and the second device;

Or after the sensing function network element receives the first indication information, the sensing function network element sends configuration information of the second signal to the first device and the second device, and activates transmission of the second signal.

Obviously, it is a preferable scheme to transmit the configuration information of the second signal together when the sensing function network element transmits the configuration information of the first signal. Because the configuration information for transmitting the second signal will have a relatively large end-to-end delay.

Embodiment four:

in this embodiment, a typical implementation of the method provided in the embodiment of the present application is mainly described.

This embodiment shows several exemplary implementations to facilitate understanding of the aspects described in the previous embodiments.

As previously described, the first signal is used to perform a sensing measurement and the second signal is used to configure the first signal to perform a round trip measurement to suppress or extract the timing start point deviation experienced by the first signal.

The span of the first signal in the time domain, which performs a perceptual measurement and obtains a perceptual result, is referred to as the coherent processing duration (Coherent processing interval, CPI) or the perceptual frame. One CPI or perceptual frame occupies M OFDM symbols in the time domain, M >1. The method provided by the embodiment of the present application may be performed in one of the following ways for the duration of one CPI:

Mode 1 the determination of LOS/NLOS status is made after M0 (M0 < M) OFDM symbols and the activation or deactivation of the second signal is made for the current CPI duration, as shown at 3 (a) in fig. 6.

In some embodiments, measuring one or more OFDM symbols may be sufficient to determine the LOS/NLOS status, and then activate or deactivate the second signal may be performed within the current CPI of the first signal. This is typically achievable since a CPI is typically on the order of ten to hundred milliseconds.

The advantage of this mode of operation is that suppression or extraction of the timing start point deviation can be performed based on the second signal at the current CPI.

Mode 2 the determination of LOS/NLOS status is made after M OFDM symbols and the activation or deactivation of the second signal is made a short time after the current CPI duration, as shown in fig. 6 (b).

In some embodiments, the first device may need to perform operations related to determining the LOS/NLOS status after receiving a first signal of CPI, and then may perform activation or deactivation of a second signal, where the second signal performs round trip measurement with the first signal of the current CPI to extract or suppress the timing start point deviation.

In some cases, such as where the timing drift of the first device and the second device is small, the second signal, which is within a certain time after the first signal of one CPI, can be suppressed or extracted from the first signal of the current CPI with sufficient accuracy.

Mode 3 judgment of LOS/NLOS status is performed after M OFDM symbols and activation or deactivation of the second signal is performed within the next CPI, as shown in (c) of fig. 6.
