[0079] In the TDD spectrum, at the same time, the base station can only send downlink signals or receive uplink signals, resulting in limited uplink resources, and the uplink coverage and latency performance of the TDD spectrum are limited. SBFD technology configures different subbands in one carrier as different transmission directions, so that there are both downlink and uplink transmission opportunities at the same time, thereby reducing the latency of the TDD system, and because the uplink transmission resources are increased, the uplink coverage is also improved.

[0080] In the SBFD system, the transmission directions of different terminals in the SBFD time slot are different, so cross-link interference between terminals will occur. In the non-SBFD time slot, the transmission direction of all terminals in the cell is the same. In order to reduce cross-link interference between terminals, one solution is to use different power control parameters in the SBFD time slot (time slots configured with uplink subbands and downlink subbands) and non-SBFD time slots (time slots without uplink subbands and downlink subbands, that is, traditional TDD time slots). For example, two sets of closed-loop power control states are used, so that the uplink transmission power of the terminal can be adjusted according to different cross-link interference situations. For example, the transmission power of the terminal is reduced in the SBFD subframe to reduce cross-link interference between terminals. In addition, under different antenna architectures, the number of base station receiving antennas is different for SBFD time slots and non-SBFD time slots. Therefore, if the same coverage is to be achieved in SBFD time slots and non-SBFD time slots, the power of the terminal in the SBFD time slot needs to be higher than the power in the non-SBFD time slot. Therefore, different power control parameters also need to be configured.

[0081] At present, there is a situation in which the terminal is not configured with two power control adjustment states in closed-loop power control, or, in some cases, the terminal uses only one power control adjustment state by default. For example, the new radio (NR) uplink power control supports configuring two sets of closed-loop power control adjustment state indexes for the terminal, and the closed-loop power control value accumulation is calculated separately according to each set of closed-loop power control adjustment state index. However, if the base station uses DCI format 0_0 scheduling or DCI format 0_1 ​​scheduling, and there is no physical uplink shared channel (PUSCH) indicated by the SRI field in the DCI, at this time, the terminal only uses the closed-loop power control adjustment state with index 0 by default, so it is impossible to use different uplink transmission powers in SBFD time slots and non-SBFD time slots, and it is impossible to reduce cross-link interference between terminals by adjusting power parameters.

[0082] Based on this, in each embodiment of the present application, the terminal determines a first value based on at least the time type of the first uplink transmission opportunity and the received TPC command, and determines the uplink transmission power at the first uplink transmission opportunity according to the determined first value. By determining the uplink transmission power of the uplink transmission opportunity through the above scheme, the terminal can use different uplink transmission powers at uplink transmission opportunities of different time types, thereby ensuring that link interference between terminals can be effectively reduced.

[0083] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0084] The present application embodiment provides a power control method, which is applied to a terminal. Figure 1 , the method comprising:

[0085] Step 101: Determine an uplink transmission power at a first uplink transmission opportunity according to a first value.

[0086] The first value is determined based on at least first information and a TPC command; the first information represents a time type of the first uplink transmission opportunity.

[0087] Here, the first value may be understood as an uplink channel and / or a component of the transmission power of the uplink channel.

[0088] In actual application, when the terminal is only configured with one power control adjustment state, the terminal determines the uplink transmission power at the first uplink transmission opportunity according to the first numerical value; and / or, when the terminal only uses one power control adjustment state, the terminal determines the uplink transmission power at the first uplink transmission opportunity according to the first numerical value.

[0089] Among them, the power control adjustment state can be configured by the network side for the terminal, or can be a default in the protocol. Taking the closed-loop power control adjustment state index as an example, in an embodiment of the present application, when the network side only configures one set of closed-loop power control adjustment state indexes for the terminal, or the network side instructs the terminal to use only one set of closed-loop power control adjustment state indexes, or the protocol defaults to configuring only one set of closed-loop power control adjustment state indexes for the terminal, or the terminal uses only one set of closed-loop power control adjustment state indexes by default according to the protocol, the terminal determines the uplink transmission power of each uplink transmission opportunity according to the first value.

[0090] The first information is used to describe the time type to which the transmission opportunity of the uplink channel and / or the uplink signal belongs. In this embodiment, the time type may include a first time type and a second time type.

[0091] The first time type may include at least one of the following:

[0092] SBFD time slot;

[0093] SBFD symbol;

[0094] A downlink timeslot or a flexible timeslot configured with uplink frequency domain resources;

[0095] Downlink symbols or flexible symbols are configured with uplink frequency domain resources.

[0096] The second time type may include at least one of the following:

[0097] Non-SBFD time slot;

[0098] Non-SBFD symbols;

[0099] Uplink timeslot configured on the network side;

[0100] Uplink symbols configured on the network side;

[0101] Flexible time slots not configured with uplink frequency domain resources;

[0102] Flexible symbols are not configured with uplink frequency domain resources.

[0103] In an embodiment of the present application, the terminal determines different uplink transmission powers for uplink transmission opportunities of different time types according to the first value.

[0104] Here, the uplink frequency domain resource can be understood as an uplink subband or uplink transmission resource in the SBFD system. The SBFD time slot can be understood as a time slot in which an uplink subband is configured in the SBFD system, and the SBFD symbol can be understood as a symbol in which an uplink subband is configured in the SBFD system.

[0105] In one embodiment, when the time type of the first uplink transmission opportunity is the first time type, the first numerical value can be represented as the sum of the cumulative value of the TPC command and the first power value; the first power value represents the power value configured by the network side or the pre-set power value; when the time type of the first uplink transmission opportunity is the second time type, the first numerical value can be represented as the cumulative value of the TPC command.

[0106] Here, the terminal determines whether to add a power value configured by the network side or predefined by the protocol based on the accumulated value of the TPC command according to the time type of the uplink transmission opportunity to determine the uplink transmission power of the uplink transmission opportunity.

[0107] Specifically, when the time type of the first uplink transmission opportunity belongs to the first time type, the first value is determined according to the following method:

[0108] The first value=the accumulated value of the TPC command within the set time period+the first power value.

[0109] When the time type of the first uplink transmission opportunity belongs to the second time type, the first value is determined according to the following method:

[0110] First value=the accumulated value of TPC commands within a set time period.

[0111] The first power value may be a positive number or a negative number.

[0112] In another embodiment, when the time type of the first uplink transmission opportunity is the first time type, the first numerical value is represented by the sum of the cumulative value of the TPC command and the first power value; the first power value represents the power value configured on the network side or the pre-set power value; when the time type of the first uplink transmission opportunity is the second time type, the first numerical value is represented by the cumulative value of the TPC command.

[0113] Specifically, when the time type of the first uplink transmission opportunity belongs to the first time type, the first value is determined according to the following method:

[0114] First value=the accumulated value of TPC commands within a set time period.

[0115] When the time type of the first uplink transmission opportunity belongs to the second time type, the first value is determined according to the following method:

[0116] The first value=the accumulated value of the TPC command within the set time period+the first power value.

[0117] The first power value may be a positive number or a negative number.

[0118] It should be noted that in actual application, the following situation 1 is equivalent to situation 2:

[0119] Case 1, the first power value is a positive number, corresponding to the first time type, the first value = the cumulative value of the TPC command within the set time period + the first power value, corresponding to the second time type, the first value = the cumulative value of the TPC command within the set time period.

[0120] Case 2, the first power value is a negative number, corresponding to the first time type, the first value = the cumulative value of the TPC command within the set time period, corresponding to the second time type, the first value = the cumulative value of the TPC command within the set time period + the first power value.

[0121] Exemplarily, for a physical uplink shared channel (PUSCH), a first value of a component of the uplink transmission power is determined according to the following method:

[0122]

[0123] Wherein, l represents the index of the closed-loop power control adjustment state of the terminal, Characterization in set D i The accumulated value of the TPC command of the PUSCH in y represents the first power value. When the uplink transmission opportunity belongs to the first time type, x=1, and when the uplink transmission opportunity belongs to the second time type, x=0; or when the uplink transmission opportunity belongs to the first time type, x=0, and when the uplink transmission opportunity belongs to the second time type, x=1. Set D i Characterizes the period from PUSCH transmission opportunity i-i0 to before symbols to PUSCH transmission opportunity i before K PUSCH(i) The TPC command received by the terminal between symbols, where i0>0, is to meet the transmission timing i-i0 before K symbols before transmission opportunity i PUSCH(i) The smallest positive integer before the last symbol. That is, all TPC commands received after the last power adjustment are accumulated. If PUSCH is scheduled by DCI, K PUSCH(i) The number of symbols between the last symbol of PDCCH and the first symbol of PUSCH transmission. If PUSCH transmission is configured by ConfiguredGrantConfig, D i The value of is the number of symbols per time slot multiplied by the smallest k2 value in PUSCH-ConfigCommon.

[0124] In the above embodiment, the terminal determines whether to add a power value to the uplink transmission power according to the type of uplink transmission opportunity. In addition, the accumulated values ​​of TPC commands belonging to different time types can be calculated respectively to determine the uplink transmission power of the uplink transmission opportunity of the corresponding time type:

[0125] In one embodiment, when the time type of the first uplink transmission opportunity is the first time type, the first numerical value can be represented as the cumulative value of the first TPC command sent by the base station in the first time period; when the time type of the first uplink transmission opportunity is the second time type, the first numerical value can be represented as the cumulative value of the second TPC command sent by the base station in the second time period.

[0126] The first TPC command represents a TPC command belonging to the first time type; the second TPC command represents a TPC command belonging to the second time type.

[0127] Here, the TPC command sent by the network side carries indication information for indicating the time type to which the TPC command carried by the TPC command belongs, or for indicating that the TPC command carried by the TPC command belongs to only one of the first time type and the second time type. In this way, the terminal determines the first power based on the cumulative value of TPC commands received within a certain time period that are consistent with the indicated time type.

[0128] Specifically, when the time type of the first uplink transmission opportunity belongs to the first time type, the first value may be determined in the following manner:

[0129] First value=the accumulated value of TPC commands belonging to the first time type in the first time period.

[0130] When the time type of the first uplink transmission opportunity belongs to the second time type, the first value is determined according to the following method:

[0131] The first value=the accumulated value of the TPC commands belonging to the second time type in the second time period.

[0132] In actual application, the first time period and the second time period may be the same time period, or may be time periods with partial overlap, or may be time periods that do not overlap.

[0133] In one embodiment, the first TPC command may be carried in a first DCI; the CRC of the first DCI may be scrambled by a first RNTI; the second TPC command may be carried in a second DCI; and the CRC of the second DCI may be scrambled by a second RNTI.

[0134] Here, the CRC of the DCI is scrambled with different RNTIs, so that the time type to which the TPC command carried by the DCI belongs is indicated by different scrambling methods. For example, the TPC command carried by the DCI scrambled with CRC using RNTI#1 belongs to the first time type, and the TPC command carried by the DCI scrambled with CRC using RNTI#2 belongs to the second time type.

[0135] In one embodiment, the first TPC command is carried in a third DCI, and the third DCI carries information indicating the first time type; or, the second TPC command is carried in a third DCI, and the third DCI carries information indicating the second time type.

[0136] In actual application, information indicating the time type to which the TPC command belongs can be carried in the information field of the DCI, for example, indicating whether the TPC command carried by the DCI belongs to the first time type or the second time type. In this way, the terminal can determine the time type to which the TPC command carried in the DCI belongs through the information carried in the information field of the DCI.

[0137] Correspondingly, the embodiment of the present application also provides a power control method, which is applied to a base station. Figure 2 , the method comprising:

[0138] Step 201: Send DCI to the terminal.

[0152] In one embodiment, sending the DCI to the terminal includes:

[0154] The CRC of the first DCI is scrambled using a first RNTI; the first RNTI corresponds to the first time type; the first DCI carries a first TPC command belonging to the first time type;

[0155] The CRC of the second DCI is scrambled using a second RNTI; the second RNTI corresponds to the second time type; the second DCI carries a second TPC command belonging to the second time type;

[0156] In one embodiment, sending the DCI to the terminal includes:

[0158] The third DCI carries the first TPC command belonging to the first time type and information for indicating the first time type, or the third DCI carries the second TPC command belonging to the second time type and information for indicating the second time type.

[0159] In the embodiment of the present application, the terminal determines a first value based on at least the time type of the first uplink transmission opportunity and the received TPC command, and determines the uplink transmission power at the first uplink transmission opportunity according to the determined first value. By determining the uplink transmission power of the uplink transmission opportunity through the above scheme, the terminal can use different uplink transmission powers at uplink transmission opportunities of different time types. For example, it can effectively distinguish the closed-loop power control of SBFD time slots and non-SBFD time slots, thereby ensuring that the link interference between terminals can be effectively reduced.
