In the mobile communication system of Time Division Duplexing (TDD) mode, the TDD base station usually uses a transceiver (with the function of receiving and transmitting signals) to alternately work in the transmitting state and the receiving state to realize signal transmission and signal transmission. take over. After the transceiver switches from the transmitting state to the receiving state, the downlink signals of adjacent base stations will generate interference after being superimposed, which may exceed the maximum receiving power allowed by the transceiver of the TDD base station, thus causing the transceiver to be saturated and blocked. cause the transceiver not to work properly. To combat saturation blocking, it is usually automatic gain control (Automatic Gain Control, AGC). When the transceiver detects that the received power is too high, it reduces the gain of the receiving amplifier to prevent the transceiver from working in a saturated state.

In the above method, since the AGC circuit detects that the input signal is too high to perform gain control, there is a time delay in the process of gain control detection, so there may still be a risk of saturation blocking before the AGC takes effect; and the AGC takes effect and recovery is affected by the input signal and interference Influenced by the intensity, if the threshold setting for triggering AGC is unreasonable, or the high-intensity input signal and interference last for a long time, the normal power amplification may not be restored when the uplink useful signal arrives, thereby reducing the sensitivity of the transceiver; or, When the AGC circuit fails, it will lose the ability to suppress the saturation blocking of the transceiver. Therefore, currently, after the transceiver is switched from the transmitting state to the receiving state, the downlink signals of adjacent base stations will generate interference after being superimposed, causing the transceiver to be saturated and blocked.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

In the description of the present application, unless otherwise specified, "/" means "or", for example, A/B may mean A or B. The "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

In the mobile communication system of TDD mode, the base station receives signals and transmits signals alternately in different time slots of the same frequency channel (ie, the same carrier), and separates the channels of receiving signals and transmitting signals through a protective time slot (Protective Gap, GP). , and the configuration of GP is usually related to the maximum coverage distance of the planned base station. A reasonable configuration of GP can ensure that terminals at the cell edge of the base station can complete cell access, and at the same time ensure that the downlink signal does not affect the uplink signal between base stations within a certain distance interval , this effect mainly means that the downlink signal of the remote base station reaches its receiver (transceiver) in the uplink time slot of another base station after a period of propagation, thus interfering with the accurate reception of its useful uplink signal.

TDD base stations usually use the same transceiver to alternately work in the transmitting state and receiving state to achieve signal reception and transmission. Usually, this type of transceiver is required to switch from the transmitting state to the receiving state, and the state transition delay from the receiving state to the transmitting state. not higher than 10 microseconds. After the transceiver is switched from transmitting to receiving state, if the receiver amplifier is turned on immediately, a large number of downlink signals from adjacent base stations will be received, especially from some not well-optimized radio frequency within the range of 3Km ~ 10Km, there is a direct path If the downlink arrival signals of these adjacent stations are superimposed and strong enough, they may exceed the maximum receiving power allowed by the receiver of the interfered base station, thus causing receiver saturation and blocking. Receiver saturation blocking will cause the receiver to fail to work normally, and long-term saturated blocking may also cause permanent performance degradation of the receiver.

To combat receiver saturation blocking, the usual technical means is to use AGC to prevent the receiver from working in a saturated state by reducing the gain of the receiving amplifier when the receiver detects that the received power is too high.

Exemplarily, as shown in FIG. 1, in a TDD mobile communication system, the downlink signals of base station 1, base station 2, and base station 3 reach the receiver of base station 4 after propagation. Due to the propagation delay and propagation loss of the downlink signals from different base stations, the There are differences, and the time and signal strength of the signal reaching the base station 4 are also different. Generally, the closer the base station is, the earlier the propagation delay and the smaller the signal attenuation. As shown in Figure 2, the downlink signals of base station 1, base station 2, and base station 3 reach the receiver of base station 4 through propagation, if the downlink signals of base station 1, base station 2, and base station 3 are in the receiving state at the transceiver of base station 4 (ie When the transceiver is the receiver) and arrives at the base station 4, the superimposition of multiple arrival signals will form the situation shown in FIG. 2 : it will gradually decrease in time. When the superimposed signal strength exceeds the maximum receiving power allowed by the receiver, it will cause the receiver of the base station 4 to be saturated and blocked.

Referring to the requirements of 3GPP for the anti-blocking ability of the base station receiver, for the coexistence of different base station frequencies, under the condition of non-co-site, when the interference power reaches -43dBm, the data service rate of the interfered base station cannot be lower than 95% of the peak rate requirement . It is reasonable to infer that for a base station receiver just meeting this anti-blocking requirement, an arriving signal of -43dBm strength would cause the receiver amplifier to go into the non-linear region, while a stronger arriving signal would push the receiver into saturation state.

Taking the 5G TDD base station working in the 3.5G frequency band as an example, as shown in Figure 2, when the receiver of base station 4 switches from the transmitting state to the receiving state, the corresponding downlink and uplink conversion time slot can contain 14 symbols, and the specific configuration is The ratio of downlink time slots, guard time slots, and uplink time slots is 10:2:2, that is, 10 downlink symbols (symbol 0 to symbol 9), 2 GP symbols (symbol 10 and symbol 11), and 2 uplink symbols ( Symbol 12 and symbol 13), and the time synchronization of the whole network.

For the transceiver of each base station, in the downlink and uplink conversion time slot, it starts to switch from the transmitting state to the receiving state after sending the last downlink symbol (ie, symbol 9), and this conversion should be completed within 10 microseconds convert. At the 10th microsecond moment corresponding to symbol 10, it receives signals from neighboring base stations (such as base station 1, base station 2, and base station 3) that arrive at the receiver of base station 4 after a propagation delay of 10 microseconds (that is, the transceiver is in the receiving state). downlink signal. If these signals arrive directly through the line of sight propagation model (Line of Sight, LOS), then these adjacent base stations are about 3Km away from the receiver of base station 4. According to the propagation model estimation, the spatial propagation loss is about 115dB.

Refer to the formula Pr=Pt+Gt-L+Gr, where Pt is the transmit power, Gt is the transmit antenna gain, L is the space propagation loss, and Gr is the receive antenna gain. When the transmitting antenna and the receiving antenna are facing each other, Gt and Gr can reach 18dBi. For 5G base stations in the 3.5G frequency band, the maximum transmission power can reach 200W/100MHz, and the transmission power at 20MHz can reach 40W, or 46dBm. Substituting the aforementioned formula, it can be obtained that the power of the receiver arriving at base station 4 Pr=Pt+Gt-L+Gr=46+18-115+18=-33dBm, if there are multiple similar LOS neighboring cells, the arriving signals will be further superimposed , thus higher than the safety threshold of -43dBm.

Similarly, if there is a neighboring cell with LOS conditions at a distance of about 6Km, the spatial propagation loss is about 122dB, and the power reaching the receiver is about -40dBm; if there is a neighboring cell with LOS conditions at a distance of about 10Km, the spatial propagation loss is about 127dB, The power reaching the receiver is about -45dBm, and the risk of being higher than -43dBm after the superposition of multiple cell signals is still very high; if there is an adjacent cell with LOS conditions at a distance of about 15Km, the spatial propagation loss is about 134dB, and the power reaching the receiver is about -52dBm, there is still a risk higher than -43dBm after the signals of multiple cells are superimposed; if there is a neighbor cell with LOS conditions at a distance of about 20Km, the spatial propagation loss is about 139dB, and the power reaching the receiver is about -57dBm, which comes from multiple neighbors After superposition of signals in the area, the risk of being higher than -43dBm is basically reduced to a safe level.

A transceiver control method provided by the embodiment of the present application can determine whether to perform AGC processing to combat possible saturation blocking without passing a period of signal strength detection, but to set or determine a value smaller than the GP based on the GP configuration size. The length of time during which the receiver is turned off to reduce unnecessary signal reception, thereby avoiding saturation blocking. This scheme does not interfere with AGC when the receiver is not in the off state.

The transceiver control method provided in the embodiment of the present application may be applicable to a transceiver control system. Fig. 3 shows a schematic structural diagram of the transceiver control system. As shown in FIG. 3 , the transceiver control system 20 includes: a first base station 21 , a second base station 22 and a third base station 23 . Wherein, the first base station 21 , the second base station 22 and the third base station 23 are used to respectively configure carriers for different terminals, and each implement information exchange with different terminals. In this embodiment of the present application, the downlink signals of the first base station 21 and the second base station 22 will interfere with the third base station 23 after being superimposed, which will cause the transceiver saturation and blocking of the third base station 23 as an example.

The transceiver control system 20 can be used in the Internet of Things, and the transceiver control system 20 can correspond to multiple base stations. In the embodiment of the present application, the first base station 21, the second base station 22 and the third base station 23 are three base stations as an example. An exemplary description is given, and the specific number of base stations is not limited in this application.

It should be noted that the first base station 21, the second base station 22 and the third base station 23 can be base stations in any mobile communication system, for example, they can be base stations in a 4G mobile communication system or a 5G mobile communication system. Not specifically limited.

Among them, the ratio of downlink and uplink conversion time slots includes: downlink time slots, guard time slots, and uplink time slots; downlink time slots are used to transmit downlink signals, guard time slots are used Receive uplink signal.

Optionally, when the transceiver of the base station switches from the transmitting state to the receiving state, it needs to enter a special time slot, that is, the downlink and uplink conversion time slot, and the down and uplink conversion time slot corresponds to a configuration (that is, the downlink and uplink conversion time slot Slot ratio), specifically the time length ratio corresponding to the downlink time slot, guard time slot, and uplink time slot. For example, the time length ratio corresponding to the downlink time slot, the guard time slot and the uplink time slot is 10:2:2 or 8:2:2.

Optionally, during the transition of the transceiver from the transmitting state to the receiving state, the transceiver can be turned off in the guard time slot after the downlink signal transmission is completed in the downlink time slot, so as to reduce receiving unnecessary interference signals , so as to avoid saturation blocking.

It can be understood that after the TDD base transceiver station completes the transition from the transmitting state to the receiving state, by adding a transceiver off state to the protection time slot based on the downlink and uplink conversion time slot ratio, the transceiver is in the off state Under this condition, no amplification and other processing is performed on the arriving interference signal, so as to avoid saturation blocking.

Optionally, the duration of controlling the transceiver to be in the off state is less than or equal to the protection duration corresponding to the protection time slot, which can ensure that when the uplink signal arrives, the uplink signal can be received in time, so as to ensure that the uplink signal will not be missed take over.

Optionally, the guard duration corresponding to the guard slot can include at least one symbol duration, and the duration of one symbol can be calculated according to the subcarrier settings. For example, in LTE and 5G NR, the symbol length corresponding to the 15kHz subcarrier is about 35.714 microseconds.

It can be understood that the duration is obtained by subtracting the transition delay corresponding to the transition from the transmitting state to the receiving state of the transceiver from the guard duration corresponding to the guard time slot.

In the embodiment of the present application, the duration of the off state of the transceiver can be determined by the difference between the protection duration corresponding to the protection time slot and the transition delay corresponding to the transition of the transceiver from the transmitting state to the receiving state, Therefore, when the uplink signal arrives, the transceiver can be controlled to be turned on in time to receive the uplink signal.

S601. Determine a fourth difference between the second difference and a turn-off delay corresponding to the transceiver, and determine the fourth difference as a duration.

Wherein, the second difference is a difference between the first difference and the corresponding turn-on delay of the transceiver.

Optionally, it is possible to determine the corresponding turn-off time delay when the transceiver is turned from the open state to the closed state, and the corresponding turn-on time delay when the transceiver is turned from the closed state to the open state, so as to determine the guard time slot On the basis of the first difference between the corresponding protection duration and the conversion delay corresponding to the transition of the transceiver from the transmitting state to the receiving state, the second difference is obtained by subtracting the corresponding turn-on delay of the transceiver from the first difference. The difference is further subtracted from the second difference by the corresponding turn-off delay of the transceiver to obtain a more accurate duration of the transceiver being in the turn-off state (that is, the fourth difference).

The embodiment of the present application provides a transceiver control method. When the transceiver of the base station switches between the transmitting state and the receiving state, the base station can transmit and receive based on the ratio of downlink and uplink conversion time slots corresponding to the transceiver.
