Some base stations may communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. Wireless communication systems may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies.

In the scenario shown in FIG. 1 , signal transmission is implemented between the network device 01 and the terminal 02 through an antenna beam, and the antenna beam is formed by a spatial transmission filter. Both the network device 01 and the terminal 02 can include multiple beams. Taking FIG. 1 as an example, it is assumed that the network device 01 includes N Transmit Receive Points (TRPs), and each TRP in the N TRPs includes an airspace transmission filters to form N beams, the terminal 02 includes M spatial transmission filters to form M beams, where N and M are both integers greater than 1. N and M may be the same or different, which is not limited in this application.

An embodiment of the present invention provides a power control method, which is applied to a terminal side. As shown in FIG. 2 , the method includes the following steps:

Step 21: Acquire the transmit power control TPC command.

In this embodiment of the present invention, the network device may include multiple TRPs, and each TRP in the multiple TRPs may include at least one (downlink) spatial transmission filter, so as to form multiple antenna port sets, or referred to as transmit port sets or A transport block, the terminal may also include multiple (upstream) spatial transmission filters to form multiple transmit port sets or transport blocks. A terminal may transmit upstream channels/signals through multiple transmit port sets or transport blocks. Wherein, uplink channels include but are not limited to: Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), etc. Uplink signals include but are not limited to Sounding Reference Signal (Sounding Reference Signal, SRS) Wait. The TPC command obtained here may be one or more (ie, at least two).

Step 22: Obtain a closed-loop power control process identifier, wherein each TPC command corresponds to at least one closed-loop power control process identifier.

The system maintains one or more closed loop power control process indexes for a TPC command.

Step 23: According to the closed-loop power control process identifier, determine the transmit power of the uplink channel/signal transmission port set or the transmission block.

The closed-loop power control process identifier corresponding to the TPC command in the prior art is corresponding to the uplink channel/signal, and the closed-loop power control process identifier corresponding to the TPC command mentioned here refers to a set of different antenna ports or transmission blocks from the terminal.

Preferably, when the terminal supports sending of uplink channels/signals on multiple sending port sets or multiple transport blocks, the DCI may include one TPC field, and each TPC field carries at least two TPC commands. For example, the terminal has two PUSCH transmissions, and the network device and the terminal pre-agreed that TPC command one in the TPC domain in the DCI corresponds to the first PUSCH, and TPC command two corresponds to the second PUSCH. When the terminal receives the DCI, the terminal will adjust the closed-loop power control adjustment amount of the first PUSCH according to the TPC command 1 in the TPC domain in the DCI; the terminal will adjust the closed-loop power control of the second PUSCH according to the TPC command 2 in the TPC domain in the DCI. Power control adjustment amount.

In addition, when the terminal supports the sending of uplink channels/signals on multiple sending port sets or multiple transport blocks, the DCI may further include at least two TPC fields, and each TPC field carries a TPC command. For example, the terminal has two PUSCH transmissions, the network device instructs the first PUSCH transmission through TPC command 1 in TPC field 0 in the DCI, and the second PUSCH transmission in TPC field 1 instructs the second PUSCH transmission. When the terminal receives DCI, the terminal will adjust the closed-loop power control adjustment amount of the first PUSCH according to TPC command 1 in TPC domain 0; the terminal will adjust the closed-loop power control adjustment amount of the second PUSCH according to TPC command 2 in TPC domain 1 .

Correspondingly, step 22 can be implemented with reference to but not limited to the following ways:

In addition, this approach is applicable to a scenario where the DCI may also include at least two TPC domains, and each TPC domain carries one TPC command.

Assuming that the terminal has two PUSCH transmissions, each PUSCH contains a closed-loop power control process, the network device and the terminal pre-agreed that the TPC commands in the TPC field 0 in the DCI correspond to the closed-loop power control process 0 of the first PUSCH, and the TCP in the DCI TPC command 2 in domain 1 corresponds to closed-loop power control process 1 of the second PUSCH.
