Description

Method for processing transmission power state conversion time and terminal
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and a terminal for processing transmit power state transition time.
Background
With the increasing improvement of the commercial use of the fourth Generation mobile communication technology (the 4th Generation mobile communication technology, abbreviated as 4G) Long-Term Evolution (Long-Term Evolution, abbreviated as LTE)/Long-Term Evolution advanced (Long-Term Evolution/LTE-a), the requirement for the technical index of the next Generation mobile communication technology, namely, the fifth Generation mobile communication technology (the 5th Generation mobile communication technology, abbreviated as 5G), is also increasing. It is widely accepted in the industry that next generation mobile communication systems should have the characteristics of ultra-high speed, ultra-high capacity, ultra-high reliability, and ultra-low delay transmission characteristics. For the index of ultra-low delay in 5G systems, it is currently accepted that the delay of the air interface is in the order of about 1 ms.
One method for effectively achieving ultra-low latency is to reduce the one-way link latency by multiple times by reducing the Transmission Time Interval (TTI) of the LTE system, so as to support the characteristic requirement of the 1ms air interface latency. The TTI is a basic unit of downlink and uplink transmission scheduling in a time domain. As in an LTE/LTE-a Frequency Division Duplex (FDD) system, the time dimension is divided into radio frames of length 10ms, where each radio frame comprises 10 subframes and the TTI length is equal to the subframe length of 1 ms. Each subframe comprises two slots, each slot having a length of 0.5 ms. Each downlink slot contains 7 Orthogonal Frequency Division Multiplexing (OFDM for short) symbols (6 OFDM symbols under the extended cyclic prefix); each uplink slot contains 7 Single Carrier-Frequency Division Multiplexing (SC-FDMA) symbols (6 SC-FDMA symbols under the extended cyclic prefix). The single carrier transmission scheme adopted by uplink transmission uses a frequency hopping technology, and the frequency hopping technology is divided into three types according to the duration of a carrier: character-based hopping, slot-based hopping and TTI-based hopping, which are not essentially different in technology.
At present, two methods for shortening TTI exist, one is to shorten the time length of a single OFDM symbol by expanding the subcarrier interval of an OFDM system, and the method is involved in a 5G high-frequency communication system and an ultra-dense network; another method is currently discussed by 3GPP (The 3rd Generation Partnership Project, third Generation Partnership Project) to reduce The TTI length by reducing The number of OFDM symbols in a single TTI, e.g., shortening The TTI to 1-7 OFDM symbols or SC-FDMA symbol lengths, which has The advantage of being fully compatible with existing LTE systems.
In the existing LTE system, the transmission power state transition time of the user terminal transmitter includes a transition process of the transmitter power from an off state to an on state (the process takes about 20 μ s) and a transition process of the transmitter power from an on state to an off state (the process takes about 20 μ s).
For a single subframe, the process of the transmitter power of the ue from the off state to the on state occurs after the subframe starts, and it takes up the time of the subframe carrying data, but because the time length of one TTI is 1ms in the conventional LTE system, the transition time of the transmitter power from the off state to the on state, 20 μ s, only takes up 2% of the TTI time length, so it is acceptable. But as the TTI length shortens, especially when the TTI equals 1 symbol, 1/14ms, 20 mus will occupy approximately 30% of the TTI length.
When a plurality of subframes are continuously transmitted, and when power varies or hops between slots or subframes, a transition time of the transmitter power from an off state to an on state and a transition time of the transmitter power from the on state to the off state are generated. As the TTI length shortens, especially when the TTI equals 1 symbol, 1/14ms, 40 μ s will occupy approximately 60% of the TTI length. This situation is a disadvantage for shortening the TTI length for improved ultra low latency scenarios, whether for a single subframe or for consecutive multiple subframes.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a flowchart of a method for processing a transmit power state transition time according to an embodiment of the present invention, as shown in fig. 1, the method of this embodiment includes:
s11, setting a time template by the terminal, wherein the time template comprises: the transition time of the transmitting power from the off state to the on state is set before the starting moment of the first transmission time interval;
and S12, the terminal carries out transmission power state conversion according to the time template in the process of sending uplink data.
The method of this embodiment already reaches the rated transmission power value of the user terminal transmitter at the beginning of TTI, so processing can obtain the maximum TTI data carrying time.
The time template for converting the transmission power of the user terminal in the embodiment described below is applicable to, but not limited to, a PUSCH (Physical Uplink Shared Channel) or a PUCCH (Physical Uplink Control Channel) with a shortened TTI length.
The first embodiment is as follows:
this embodiment provides a transmission power conversion time template of a user terminal transmitter when a single TTI is transmitted and a schematic diagram of power conversion time when the corresponding TTI is 1 symbol. As shown in fig. 2, when transmitting in a single TTI, the time for the user terminal transmitter power to transition from the off state to the on state is completed before the TTI starts, i.e., the nominal transmission power value of the user terminal transmitter has been reached at the start of the TTI. This process results in a maximum TTI-bearing data time.
As previously discussed, the transition period of the transmission power from the OFF state to the ON state is about 20 μ s, and when the TTI is shortened to 1 symbol, i.e., (1/14) ms is about 71 μ s, the transition of the transmission power from the OFF state to the ON state is completed before the TTI begins, thus saving 20 μ s of time for transmitting data. This is a very effective way to improve the data transmission efficiency for a duration of a TTI total length of only 71 mus.
The power conversion time template for single TTI transmission shown in fig. 2 is applicable not only to 1 symbol, but also to 2, 3, 4, 5, 6, 7 symbols for TTI, etc.
In addition, the transition process of the transmission power from the on state to the off state, i.e. the power down phase, continues to maintain the transition time template of the transmission power of the existing LTE user terminal from the on state to the off state, i.e. the power down state is started only when the subframe ends, and the time for which the user terminal continuously operates at the rated transmission power value is equal to one transmission time interval.
Therefore, as shown in fig. 2, when transmitting in a single TTI, the power conversion time of the user terminal transmission power does not occupy the time of carrying data in any TTI.
Example two:
this embodiment provides a transmission power conversion time template of a user terminal transmitter when consecutive TTIs are transmitted and a schematic diagram of power conversion time when the corresponding TTI is 2 symbols. As shown in fig. 3(a) -3 (c), a time template of the transmission power conversion when hopping between two TTIs is given.
As shown in fig. 3(a), each TTI is subject to a time translation template when a single TTI is transmitted. That is, the transition of the transmission power from the off state to the on state is completed before the TTI starts, and the transition of the transmission power from the on state to the off state is completed after the TTI ends. Thus, the duration of operation of the user terminal at the nominal transmission power value in each TTI is equal to one transmission time interval. For the current TTI, the bearer data time is maximized. Although interference between a previous TTI power down process and a next TTI power up process is caused at the beginning of a next TTI, a Cyclic Prefix (CP) begins to exist in the TTI, and the influence of the interference can be reduced to a certain extent.
As shown in fig. 3(b), except that the transition of the transmission power of the first TTI from the off state to the on state is completed before the TTI starts and the transition of the transmission power of the last TTI from the on state to the off state is completed after the TTI ends, the power up and power down process is completed within the TTI time of each TTI, and the transition time of the transmission power of the user terminal from the off state to the on state in each TTI cannot be earlier than the current TTI start time; and the time for converting the transmitting power of the user terminal from the on state to the off state cannot be later than the current TTI ending time. The total time of the transition time of the transmission power from the off state to the on state, the rated transmission power duration of the user terminal and the transition time of the transmission power from the on state to the off state in each TTI is equal to one TTI.
In this embodiment, in the first TTI, the sum of the time that the ue continuously operates at the rated transmission power and the time that the transmission power of the ue transits from the on state to the off state is equal to the first TTI. The conversion time of the transmitting power of the user terminal from the closed state to the open state in the first TTI cannot be later than the starting time of the first TTI; and the time for converting the transmitting power of the user terminal from the on state to the off state cannot be later than the end time of the first TTI.
In the last TTI, the sum of the transition time of the transmission power of the user terminal from the off state to the on state and the time that the user terminal continuously operates at the rated transmission power is equal to the last TTI. The time for the user terminal transmitting power to change from the closed state to the open state in the last TTI cannot be earlier than the starting time of the last TTI; the transition time of the user terminal transmitting power from the on state to the off state cannot be earlier than the end time of the last TTI.
This process maximizes the reduction of power up and power down interference between TTIs, where the interference from transmit power conversion processes in different TTIs exists outside the CP at the beginning of each TTI, but reduces the time that the TTI carries data transmissions, e.g., for an intermediate TTI, there may be two conversions of power down and power up.
As shown in fig. 3(c), in this embodiment, the time for the ue to transition from the off state to the on state in the first TTI cannot be later than the start time of the first TTI; the transition time of the transmitting power of the user terminal from the on state to the off state cannot be earlier than the end time of the first TTI. The time for the user terminal transmitting power to change from the closed state to the open state in the last TTI cannot be earlier than the starting time of the last TTI; the transition time of the user terminal transmitting power from the on state to the off state cannot be earlier than the end time of the last TTI.
When frequency hopping is carried out among TTIs, the power reduction and conversion process is started after the previous TTI is finished, and the power rising process is started after the next TTI is started. That is, the time for the user terminal transmitting power to change from the off state to the on state in each TTI cannot be earlier than the current TTI starting time; the transition time of the user terminal transmission power from the on state to the off state cannot be earlier than the current TTI end time. Except the first and last TTIs, the sum of the time for the user terminal to convert the transmission power from the off state to the on state in each TTI and the time for the user terminal to continuously work at the rated transmission power is equal to the current TTI. In this embodiment, the interference of the transmit power conversion process in different transmission time intervals exists only in the CP at the beginning of each transmission time interval.
The transmission power conversion time template in this way can increase the data transmission time carried by the previous TTI, i.e. improve the performance, and although the interference of transmission power conversion with power rising and power falling at the beginning of the next TTI is caused, because the CP exists at the beginning of the TTI, especially for extended cyclic prefix (extended cyclic prefix), the CP duration is about 16.67 μ s, which can substantially eliminate the power conversion interference of 20 μ s, and the interference effect is reduced to a certain extent.
The process of fig. 3(c) is a compromise between reducing interference and effectively carrying data transfer time. Except for the first TTI, the transmission power conversion process from the off state to the on state is completed before the TTI begins, the rest of the continuous transmission TTIs only have one power rising conversion time in the TTI duration, and under the extended CP, the power conversion interference can be mostly eliminated.
Example three:
this embodiment provides a schematic diagram of a transmit power conversion time template and a power conversion time of a user terminal transmitter when the TTI length is equal to 4 symbols and frequency hopping is performed between TTIs when consecutive TTIs are transmitted. As shown in fig. 4, when hopping between TTIs, power decrease starts after the end of the previous TTI, and power increase starts after the start of the next TTI. The transmit power translation time-stamp of this approach is currently a compromise between reducing interference and effectively carrying data transfer time. Not only the data transmission time borne by the previous TTI is increased, but also under the condition that a CP exists at the beginning of the next TTI, certain power conversion interference can be eliminated. And when the TTI is 4 symbols, i.e., the TTI duration is approximately 286 μ s and hopping between TTIs, a power conversion cycle of 20 μ s occupies a smaller proportion of the TTI duration.
Example four:
this embodiment provides a transmission power conversion time template of a user terminal transmitter when consecutive TTIs are transmitted and a schematic diagram of power conversion time when the corresponding TTI is 7 symbols. As shown in fig. 5, each TTI finishes power up and power down within its TTI time, except that the power up state of the first TTI is completed before the TTI starts and the power down state of the last TTI is completed after the TTI ends. Namely, the method of the power conversion time template when the existing LTE is continuously transmitted by a plurality of TTIs is kept. This process may maximize the reduction of power up and power down interference between TTIs, but may reduce the time for a TTI to carry a data transmission, e.g., for an intermediate TTI, there may be a transition between power up and power down. However, when the TTI is 7 symbols, i.e., 0.5ms, the ratio of the two conversion times to the TTI duration is only about 8%, which is still a feasible time template.
The above embodiment is a time template for the terminal equipment transmitter to transmit power state transition when frequency hopping or transmission power change occurs between a plurality of consecutive TTIs. The time template for the transition of the transmission power state of the terminal equipment transmitter when frequency hopping or transmission power change occurs between consecutive symbols in TTI is described below.
In this embodiment, a TTI includes 1 to 7 symbols, when frequency hopping or transmission power change occurs between consecutive N symbols, the length of N is any integer between [2 and 7], and the time template for the terminal device transmitter to transmit power state transition includes any one of the following:
A. the time that the user terminal continuously works at the rated transmission power value in the continuous N symbols is equal to the length of the N symbols, and the conversion time of the transmission power of the user terminal from the closed state to the open state cannot be later than the starting time of the current N symbols; and the time for the transmission power of the user terminal to be converted from the on state to the off state cannot be earlier than the end time of the current N symbols. In the time template, partial interference generated in the transmission power conversion process between the continuous N symbols exists in a cyclic prefix at the beginning of the symbol;
B. the transition time of the user terminal transmitting power from the off state to the on state, the time of the user terminal continuously working at the rated transmitting power value and the transition time of the user terminal transmitting power from the on state to the off state in the continuous N symbols are equal to the length of N symbols. The conversion time of the transmitting power of the user terminal in the N symbols from the closed state to the open state cannot be earlier than the starting time of the current N symbols; and the conversion time of the transmitting power of the user terminal from the on state to the off state cannot be later than the end time of the current N symbols. In the time template, interference generated by the transmission power conversion process between the continuous different N symbols exists outside the cyclic prefix at the symbol start.
C. The sum of the transition time of the user transmission power from the off state to the on state in the continuous N symbols and the time that the user terminal continuously operates at the rated transmission power value is equal to the length of N symbols. The conversion time of the transmitting power of the user terminal from the closed state to the open state in the N symbols cannot be earlier than the starting moment of the current symbol; the transition time of the transmitting power of the user terminal from the on state to the off state can not be earlier than the end time of the current symbol. With this time-slicing, the interference generated by the transmit power conversion process between consecutive N symbols exists only within the cyclic prefix at the beginning of the symbol.
The following describes a specific embodiment of a time template for the transmission power state transition of the terminal equipment transmitter when frequency hopping or transmission power change occurs between consecutive symbols in a TTI.
Example five:
this embodiment provides a schematic diagram of a transmit power conversion time template and a power conversion time of a user terminal transmitter when the TTI length is equal to 4 symbols and frequency hopping between symbols is performed during continuous TTI transmission. As shown in fig. 6, when hopping between two symbols, the power starts to decrease after the first 2 symbols end, and the power starts to increase after the second two symbols start. The transmit power conversion time of this current approach is a compromise between reducing interference and effectively carrying data transfer time. Namely, the data transmission time carried by the first 2 symbols is increased, and under the condition that a CP exists at the beginning of the latter symbols, certain power conversion interference can be eliminated. And when frequency hopping is carried out between two symbols, namely, the duration is about 143 μ s, the proportion of the duration of two symbols occupied by one power conversion cycle 20 μ s is slightly larger than that of TTI embodiment three (in embodiment three, the duration of TTI is about 286 μ s, and the proportion of power conversion cycle 20 μ s is 20/286 ═ 7%;. in this embodiment, the proportion of power conversion cycle 20 μ s is 20/143 ═ 14%. therefore, the proportion is slightly larger than that of TTI embodiment three).
Example six:
the above embodiments (i.e. embodiments one to five) are also applicable to the case where the transmission power varies between TTIs or between symbols. The processing method of the power conversion time in the power up process and the power down process is the same as that when frequency hopping occurs between consecutive TTIs or between symbols, and is not described herein again.
Example seven:
the above embodiments (i.e., embodiments one to five) are all the time templates and schematic diagrams for the transmit power conversion of the user terminal transmitter under the assumption that there is frequency hopping and/or transmit power variation between TTIs or between symbols.
As shown in fig. 7, when there is no frequency hopping or transmission power variation between TTIs or between symbols, there is no transition time between TTIs or between symbols for power up and power down. The power increase is completed only before the first TTI begins, the power decrease is started when the last TTI ends, and the rest continuous TTIs are operated by continuously keeping the rated transmission power of the user terminal.
