[0080] The present application is further described in detail below in conjunction with embodiments.

[0081] For closed-loop power control of the uplink channel, the transmit power of the uplink control channel can be quickly adjusted by sending a TPC command via downlink control information (DCI).

[0082] For a TPC command specific to a user equipment (UE), a DCI format 0_0 / 0_1 / 1_0 / 1_1 is used, and the TPC command is sent along with an uplink (UL) or downlink (DL) grant, and 2 bits are used to indicate an adjustment amount of the TPC command.

[0083] For the group common TPC command (Group common TPC command), that is, multiple UEs configure the TPC command at the same time, the DCI format used is DCI format 2_2, which includes block number 1, block number 2, …, block number Q; each UE configures the TPC index (tpc-Index in English) through RRC signaling to indicate which block is used for itself.

[0084] Each block number contains 1 bit of closed loop and 2 bits of TPC command; the close loop may not exist, so each block number contains 2 bits (no close loop) or 3 bits. Here, for each terminal, two sets of closed-loop power control adjustment methods can be configured. When two sets of closed-loop power control adjustment methods are configured for the terminal, it is necessary to indicate which set to use. For example, there is one set of closed-loop power control adjustment methods for normally scheduled PUSCH transmission, and one set of closed-loop power control adjustment methods for unscheduled PUSCH transmission. When one set of closed-loop power control adjustment methods is configured for the terminal, the block number does not contain close loop.

[0085] When the terminal sends an uplink channel, it will accumulate the TPC commands in all previously received DCIs. The power adjustment values ​​corresponding to the TPC command field in the DCI are shown in Table 1 and Table 2. Here, Table 1 shows the power adjustment values ​​corresponding to PUSCH transmission; Table 2 shows the power adjustment values ​​corresponding to PUCCH transmission.

[0090] By receiving the uplink channel through multiple TRPs, the reliability of the uplink channel transmission can be improved and the robustness of the uplink channel can be increased.

[0091] In this case, when the solution of the related art is adopted, although one DCI can schedule the uplink channels of two TRPs for repeated transmission, only one TPC command can be indicated. Therefore, when the terminal receives the TPC command, it cannot distinguish which uplink channel among the uplink channels received by multiple TRPs the TPC command is for. Therefore, the power of all uplink channels can only be adjusted in the same way, such as Figure 2 As shown. However, in many cases, the channels of multiple TRPs are different, and the power control adjustments are also different. Take TRP0 and TRP1 receiving PUSCH as an example. Since the channels of the two TRPs are completely different, in order to ensure that the uplink channel performance received by the two TRPs is relatively good, when the terminal performs multiple PUSCH repetitions, some transmissions may be based on the parameters set by the channel of TRP0, and some transmissions may be based on the parameters set by the channel of TRP1. Among them, the most obvious difference is the transmit power of the PUSCH received by the two TRPs. Of course, PUCCH also has similar problems as mentioned above.

[0092] Based on this, in various embodiments of the present application, the terminal adjusts the transmission power of the uplink channel based on at least two TPC commands.

[0093] In the embodiment of the present application, since the terminal adjusts the power of the uplink channel based on at least two TPC commands, when multiple TRPs are used to receive the uplink channel, it is possible to adjust the transmission power of the uplink channel according to the parameters set by the corresponding TRP channel and utilize the corresponding TPC command to flexibly adjust the closed-loop power of the uplink channel received by multiple TRPs.

[0094] The embodiment of the present application provides an uplink channel power control method, which is applied to a network device (specifically, a base station), and the method includes:

[0095] Sending first information to a terminal; the first information indicates at least two TPC commands; the first information is used by the terminal to adjust the power of an uplink channel using the at least two TPC commands.

[0096] In actual application, the network device may send the first information to the terminal via DCI or MAC CE.

[0097] Here, when the first information is sent to the terminal via DCI, the format of the DCI may adopt DCI format 2_2, each block number corresponds to a TPC command, and the terminal may select at least two TPC commands from multiple block numbers to adjust the power of the uplink channel.

[0098] The application scenarios of the embodiments of the present application are as follows: Figure 1 As shown, in this scenario, using one set of RRC parameters, two TRPs can be used to send one DCI scheduling terminal to send an uplink channel, or one TRP can be used to send one DCI scheduling terminal to send an uplink channel, and the uplink channel can be received through two TRPs, for example, through two TRPs to receive a repeatedly transmitted (repetition in English) uplink channel.

[0099] In this scenario, it is necessary to indicate that the terminal has two tpc-Index, corresponding to two TRPs, that is, one TRP each, so that the terminal can know that it needs to obtain two TPC commands. Accordingly, when there are multiple TRPs, it is necessary to indicate that the terminal has multiple tpc-Index, each tpc-Index corresponds to one TRP.

[0100] Based on this, in one embodiment, the method may further include:

[0101] Sending second information to the terminal; the second information indicates at least two TPC indexes.

[0102] Among them, each TRP corresponds to a TPC index.

[0103] Here, in actual application, the second information, such as an RRC reconfiguration message, etc., may be sent to the terminal via RRC or MAC CE signaling.

[0104] In practical application, the uplink channel includes at least one of the following:

[0105] PUSCH;

[0106] PUCCH.

[0107] In actual application, the network device may further send other information as needed to indicate a TPC command different from the TPC command indicated by the first information.

[0108] Based on this, in one embodiment, the method may further include:

[0109] Sending third information to the terminal; the third information indicates a TPC command.

[0110] In actual application, the third information may be sent to the terminal via DCI or MACE; in this case, the TPC command is a TPC command exclusively used by the terminal.

[0111] Here, for the terminal, when the detection timing of the third information and the detection timing of the first information are in the same time window, the terminal needs to perform conflict processing, that is, it needs to determine how to use these TPC commands to adjust the transmission power of the uplink channel.

[0112] In one embodiment, the method may further include:

[0113] Sending fourth information to the terminal; the fourth information indicates a TPC command.

[0114] In actual application, the fourth information may be sent to the terminal via DCI or MACE; at this time, the TPC command is a TPC command exclusively for the terminal.

[0115] Here, for the terminal, when the interval between the detection timing of the third or fourth information and the detection timing of the first information is less than a threshold, the terminal needs to perform conflict processing, that is, it needs to determine how to use these TPC commands to adjust the transmission power of the uplink channel.

[0116] Accordingly, the embodiment of the present application also provides an uplink channel power control method, which is applied to a terminal, such as Figure 3 As shown, the method includes:

[0117] Step 301: Receive first information sent by a network side; the first information indicates at least two TPC commands;

[0118] Step 302: Use the at least two TPC commands to adjust the power of the uplink channel.

[0119] Among them, for step 301, in one embodiment, the first information sent by the network side can be received through DCI or MAC CE; specifically, when the network side sends the first information through DCI, the terminal receives the first information through DCI; when the network side sends the first information through MAC CE, the terminal receives the first information through MAC CE.

[0120] In one embodiment, the method may further include:

[0121] Receive second information sent by the network side; the second information indicates at least two TPC indexes.

[0122] Among them, each TRP corresponds to a TPC index.

[0123] Here, in actual application, the second information sent by the network side may be received through RRC signaling or MAC CE.

[0124] In the embodiment of the present application, in order to improve the reliability of the uplink channel, the uplink channel can be transmitted repeatedly.

[0125] In actual application, in step 302, the uplink channel that is repeatedly transmitted N times may correspond to the order of at least two TPC commands in the first information (ie, the ordering result of at least two TPC commands in the first information); N is an integer greater than or equal to 2.

[0126] Specifically, the first TPC command corresponds to the transmission from the first to the N / Mth uplink channel; the second TPC command corresponds to the transmission from the N / M+1th to the 2N / Mth uplink channel; and so on, the Mth TPC command corresponds to the transmission from the (M-1)*N / M+1th to the Nth uplink channel; M represents the number of TPC commands. That is, the 1st to Nth repeated transmissions are grouped, each group has N / M repeated transmissions, and each group corresponds to one TPC command; specifically, according to the order of grouping, the first group corresponds to the first TPC command, the second group corresponds to the second TPC command, and so on, the Mth group corresponds to the last TPC command of at least two TPC commands. For example, assuming that 2 TRPs are used to receive the repeatedly transmitted PUSCH, when the first information is received through DCI, the terminal can select 2 blocknumbers from DCI format 2_2 for power control adjustment of the PUSCH of the 2 TRPs; at this time, the first TPC command corresponds to the first N / 2 PUSCH transmissions, and the second TPC command corresponds to the last N / 2 PUSCH transmissions. Of course, the repeated transmission of PUCCH also uses the above method.

[0127] That is to say, in the case where the at least two TPC commands correspond to the uplink channel that is repeatedly transmitted N times in sequence, that is, when the at least two TPC commands correspond to the uplink channel that is repeatedly transmitted N times in sequence, the at least two TPC commands and the N transmissions can be mapped sequentially. This method allows the terminal to use the same transmission power in the uplink channel of continuous transmission, thereby reducing the complexity of terminal implementation.

[0128] In actual application, the at least two TPC commands may also correspond to the uplink channel that is repeatedly transmitted N times in a cyclic manner.

[0129] Specifically, the first TPC command corresponds to the first uplink channel transmission, the second TPC command corresponds to the second uplink channel transmission; and so on, the Mth TPC command corresponds to the Mth uplink channel transmission; M represents the number of TPC commands. Wherein, when it is greater than M, the first TPC also corresponds to the M+1th uplink channel transmission, the second TPC also corresponds to the M+2th uplink channel transmission, and so on.

[0130] That is to say, M TPC command cycles correspond to N transmissions. For example, assuming that 2 TRPs are used to receive the repeatedly transmitted PUSCH, when the first information is received through DCI, the terminal can select 2 block numbers from DCI format 2_2 for the power control adjustment of the PUSCH of the 2 TRPs; at this time, the first tpc-Index corresponds to the odd-numbered PUSCH transmissions, and the second tpc-Index corresponds to the even-numbered PUSCH transmissions. Of course, the repeated transmission of PUCCH also uses the above method.

[0131] That is to say, in the case where the at least two TPC commands correspond to an uplink channel that is repeatedly transmitted N times in a cyclic manner, that is, when the at least two TPC commands correspond to an uplink channel that is repeatedly transmitted N times in a cyclic manner, the at least two TPC commands and the N transmissions may adopt a cyclic mapping method, which may provide better robustness.

[0132] Among them, in the above example, the network side configures two tpc-Index through RRC signaling, corresponding to 2 TRPs, so as to know that 2 TPC commands need to be obtained. After the terminal receives the DCI in DCI format 2_2 format, assuming that tpc-Index={1,2} is configured, it means that block number 1 and block number 2 in the DCI correspond to the TPC command of the PUSCH or PUCCH corresponding to the first TRP of the terminal and the TPC command of the PUSCH or PUCCH corresponding to the second TRP:

[0133] Among them, the two tpc-Index configuration information configured by RRC can correspond to any one of block number 1, block number 2,…, block number Q (which can be determined as needed).

[0134] In actual application, when the network side also sends other information to the terminal to indicate a TPC command different from the TPC command indicated by the first information, for the terminal, when the detection timing of the other information and the detection timing of the first information are located in the same time window, or when the detection timing of the other information and the detection timing of the first information are less than a threshold, the terminal needs to perform conflict processing, that is, it needs to determine how to use these TPC commands to adjust the transmission power of the uplink channel.

[0135] Based on this, in one embodiment, the method may further include:

[0136] receiving third information sent by the network side; the third information indicates a TPC command;

[0137] When the detection timing of the third information and the detection timing of the first information are in the same time window, perform one of the following operations:

[0138] Ignore the TPC command indicated by the third information;

[0139] The value of the TPC command indicated by the third information and the value corresponding to the first TPC command among the at least two TPC commands are accumulated to adjust the power of the uplink channel corresponding to the first TPC command; and the other TPC commands except the first TPC command among the at least two TPC commands are used to adjust the power of the corresponding uplink channel.

[0140] Here, in actual application, the detection timing of the third information may be the same as or different from the detection timing of the first information. The above operation needs to be performed as long as the detection timing of the third information and the detection timing of the first information are within a time window.

[0141] Exemplarily, when the terminal receives a group common DCI (in the format of DCI format 2_2, i.e., the first information) and a UE specific DCI (in the format of DCI format 0_0, or 0_1, or 1_0, or 1_1, i.e., the third information) at different physical downlink control channel (PDCCH) detection times, and both are located within a time window W, the terminal ignores the TPC indication (i.e., TPC command) of the UE specific DCI within this time window W, and only controls and adjusts the uplink channel power according to the TPC command indicated by the group common DCI; or, the terminal accumulates the TPC command indicated by the UE specific DCI and the first TPC command indicated by the group common DCI to adjust the power of the uplink channel corresponding to the first TPC command indicated by the group common DCI, and only adjusts the power of the uplink channel corresponding to it according to the second TPC command indicated by the group common DC, such as Figure 4 shown.

[0142] Among them, it should be noted that when the terminal UE receives the groupcommon DCI and the UE-specific DCI at the same PDCCH detection time, the same processing method as above is sampled, that is, the TPC indication (i.e., TPC command) of the UE-specific DCI within this time window W is ignored, and the uplink channel power is only controlled and adjusted according to the TPCcommand indicated by the group common DCI; or, the terminal accumulates the TPCcommand indicated by the UE-specific DCI and the first TPC command indicated by the group common DCI to adjust the power of the uplink channel corresponding to the first TPC command indicated by the groupcommon DCI, and only adjusts the power of the uplink channel corresponding to it according to the second TPC command indicated by the group common DC, such as Figure 4 shown.

[0143] In actual application, the size of the time window can be set as needed.

[0144] In one embodiment, the method may further include:

[0145] receiving fourth information sent by the network side; the fourth information indicating a TPC command;

[0146] When the interval between the detection timing of the fourth information and the detection timing of the first information is less than a threshold, perform one of the following operations:

[0147] Ignore the TPC command indicated by the fourth information;

[0148] The value of the TPC command indicated by the fourth information and the value corresponding to the first TPC command among the at least two TPC commands are accumulated to adjust the power of the uplink channel corresponding to the first TPC command; and the other TPC commands except the first TPC command among the at least two TPC commands are used to adjust the power of the corresponding uplink channel.

[0149] Here, in actual application, the detection timing of the fourth information may be the same as or different from the detection timing of the first information. The above operation needs to be performed as long as the interval between the detection timing of the fourth information and the detection timing of the first information is within a threshold.

[0150] Exemplarily, when the terminal receives a group common DCI (in the format of DCI format 2_2, i.e., the first information) and a UE specific DCI (in the format of DCI format 0_0, or 0_1, or 1_0, or 1_1, i.e., the fourth information) at different physical downlink control channel (PDCCH) detection times, and the detection time interval between the two is less than a threshold T, the terminal ignores the TPC indication (i.e., TPC command) of the UE specific DCI within this threshold T, and only controls and adjusts the uplink channel power according to the TPC command indicated by the group common DCI; or, the terminal accumulates the TPC command indicated by the UE specific DCI and the first TPC command indicated by the group common DCI to adjust the power of the uplink channel corresponding to the first TPC command indicated by the group common DCI, and only adjusts the power of the uplink channel corresponding to it according to the second TPC command indicated by the group common DC. Of course, PUCCH can also be processed in the above manner, such as Figure 4 shown.

[0151] It should be noted that when the terminal UE receives the groupcommon DCI and the UE-specific DCI at the same PDCCH detection timing, the same processing method as above is sampled, that is, the TPC indication (i.e., TPC command) of the UE-specific DCI within the threshold T is ignored, and the uplink channel power is only controlled and adjusted according to the TPCcommand indicated by the group common DCI; or, the terminal accumulates the TPCcommand indicated by the UE-specific DCI and the first TPC command indicated by the group common DCI to adjust the power of the uplink channel corresponding to the first TPC command indicated by the groupcommon DCI, and only adjusts the power of the uplink channel corresponding to the second TPC command indicated by the group common DC.

[0152] In actual application, the size of the threshold can be set as needed.

[0153] For the above example, considering that the group common DCI can be a TPC that independently indicates 2 TRPs, the group common DCI can achieve better performance than other DCIs. Therefore, it is believed that the group common DCI has a higher priority, so the uplink channel power can be controlled and adjusted only according to the TPC command indicated by the group common DCI.

[0154] Taking into account that all DCIs are sent by the base station, the TPC command of each DCI is meaningful, so no priority is stipulated, only the calculation behavior is stipulated. At this time, the terminal accumulates the TPC command indicated by the UE-specific DCI and the first TPC command indicated by the group common DCI to adjust the power of the uplink channel corresponding to the first TPC command indicated by the group common DCI, and only adjusts the power of the uplink channel corresponding to the second TPC command indicated by the group common DC.

[0155] Therefore, in actual application, the TPC command indicated by the third information or the fourth information can be ignored as needed; or the value of the TPC command indicated by the third information or the fourth information and the value corresponding to the first TPC command of the at least two TPC commands are accumulated to adjust the power of the uplink channel corresponding to the first TPC command; and the other TPC commands except the first TPC command of the at least two TPC commands are used to adjust the power of the corresponding uplink channel.

[0156] The present application also provides an uplink channel power control method, such as Figure 5 As shown, the method includes:

[0157] Step 501: The network device sends first information to the terminal; the first information indicates at least two TPC commands;

[0158] Step 502: After receiving the first information, the terminal uses the at least two TPC commands to adjust the power of the uplink channel.

[0159] Here, it should be noted that the specific processing process of the network device and the terminal has been described in detail above and will not be repeated here.

[0160] In the uplink channel power control method provided by the embodiment of the present application, the network device sends a first message to the terminal; the first message indicates at least two TPC commands; the terminal adjusts the power of the uplink channel using the at least two TPC commands. In the scheme provided by the embodiment of the present application, since the terminal adjusts the power of the uplink channel based on at least two TPC commands, when multiple TRPs are used to receive the uplink channel, the corresponding TPC command can be used to adjust the transmission power of the uplink channel according to the parameters set by the corresponding TRP channel, and the closed-loop power of the uplink channel received by multiple TRPs can be flexibly adjusted.
