Background

In a mobile communication system, each uplink channel or reference signal of a terminal maintains at most two closed-loop power control processes, and when the terminal supports only a single uplink information transmission, one of the two closed-loop power control processes can be used for transmission power adjustment of the uplink information. However, when the terminal supports simultaneous transmission of multiple uplink messages, the two closed-loop power control processes can only dynamically adjust the transmission power of one uplink message, and if all uplink messages adopt the same closed-loop power control process to adjust the transmission power at the same time, power control may be inaccurate, which not only increases the power consumption of the terminal, but also fails to meet the coverage requirement of the system. Or, when the terminal supports one uplink message for multi-antenna port transmission, if different antenna ports use the same closed-loop power control process, the power control of the antenna ports may also be inaccurate, thereby reducing the uplink transmission rate.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a network device 01 and a terminal 02. Wherein, the network device 01 may be a Base Station or a core network, wherein the Base Station may be a Base Station of 5G and later versions (e.g. a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g. an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a basic Service Set (basic Service Set, BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention only takes the Base Station in the NR system as an example, but does not limit the specific type of base station. The terminal 02 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 02 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable Device (wearable Device), or a vehicle-mounted Device, and a specific type of the terminal 02 is not limited in the embodiment of the present invention.

The base stations may communicate with the terminal 02 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with terminal 02 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 02 to network device 01) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 01 to terminal 02). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission.

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

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

step 21: a transmit power control, TPC, command is obtained.

In the embodiment of the present invention, a network device may include a plurality of TRPs, each of the plurality of TRPs may include at least one (downlink) spatial domain transmission filter to form a plurality of antenna port sets, or referred to as transmit port sets or transmission blocks, and a terminal may also include a plurality of (uplink) spatial domain transmission filters to form a plurality of transmit port sets or transmission blocks. The terminal may transmit the uplink channel/signal through a plurality of transmission port sets or transport blocks. The uplink channel includes, but is not limited to: a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and the like, and the Uplink Signal includes, but is not limited to, a Sounding Reference Signal (SRS) and the like. The TPC command acquired here may be one or plural (i.e., at least two).

Step 22: and acquiring 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 identifiers (closed loop power control process index) for one TPC command.

Step 23: and determining the transmitting power of a transmitting port set or a transmission block of the uplink channel/signal according to the closed-loop power control process identification.

In the prior art, the closed-loop power control process identifier corresponding to the TPC command corresponds to an uplink channel/signal, and the closed-loop power control process identifier corresponding to the TPC command refers to a closed-loop power control process identifier corresponding to a different antenna port set or a transmission block of the terminal. Therefore, the transmission power of different antenna ports or transmission blocks can be flexibly and accurately controlled according to the closed-loop power control process expression.

Wherein step 21 can be obtained by, but is not limited to, the following:

the method comprises the steps of firstly, receiving downlink control information DCI; and acquiring the TPC command from the DCI.

The TPC commands for the transmission port sets or transport blocks of different uplink channels/signals may be indicated by DCIs of different formats, for example, the TPC commands for the transmission port sets or transport blocks of PUSCH may be indicated by DCI format 0_0 or 0_1, and the TPC commands for the transmission port sets or transport blocks of PUCCH may be indicated by DCI format 1_0 or 1_ 1. The TPC command of the transmission port set or the transport block of different uplink channels/signals may maintain one closed-loop power control process identifier, or may maintain two closed-loop power control process identifiers. Whether one TPC command maintains one or two closed loop power control process identifiers, the TPC command may be 2 bits.

Specifically, the DCI may include at least one TPC field, and each TPC field in the DCI carries at least one TPC command. Preferably, when the terminal supports that the uplink channel/signal is transmitted on a plurality of transmission port sets or a plurality of 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, the network device and the terminal agree in advance that a TPC command one in a TPC domain in DCI corresponds to a first PUSCH, and a TPC command two corresponds to a second PUSCH. When the terminal receives DCI, the terminal adjusts the closed loop power control adjustment quantity of the first PUSCH according to a TPC command I in a TPC domain in the DCI; and the terminal adjusts the closed-loop power control adjustment quantity of the second PUSCH according to the TPC command II in the TPC domain in the DCI.

In addition, when the terminal supports that the uplink channel/signal is transmitted on a plurality of transmission port sets or a plurality of transmission blocks, the DCI may further include at least two TPC fields, and each TPC field carries one TPC command. For example, there are two PUSCH transmissions for the terminal, the network device indicates the first PUSCH transmission by TPC command one in TPC field 0 in DCI, and indicates the second PUSCH transmission by TPC command two in TPC field 1. When the terminal receives DCI, the terminal adjusts the closed loop power control adjustment quantity of the first PUSCH according to the TPC command I in the TPC domain 0; the terminal will adjust the closed loop power control adjustment of the second PUSCH according to TPC command two in TPC field 1.

Accordingly, step 22 may be implemented in the following manner, but is not limited to:

and the mode 1-1 determines the closed loop power control process identifier corresponding to the TPC command according to the TPC domain.

The method is that DCI explicitly indicates a closed loop power control process identifier corresponding to a TPC command, and the method is suitable for a scene that DCI can comprise one TPC domain, and each TPC domain carries at least two TPC commands.

A second mode is that group common DCI is received; the TPC commands are acquired from the group common DCI.

Here, the TPC commands of the transmission port sets or transport blocks of different uplink channels/signals may be indicated by Group Common (Group Common) DCIs of different formats, for example, the TPC commands for the transmission port sets or transport blocks of PUSCH/PUCCH are indicated by DCI format 2_2, and the transmission port or transport block of SRS is indicated by DCI format 2_ 3. The TPC command of the transmission port set or the transport block of different uplink channels/signals may maintain one closed-loop power control process identifier, or may maintain two closed-loop power control process identifiers. For the TPC command corresponding to the PUSCH, when one TPC command corresponds to one closed loop power control process identifier, the TPC command may be 2bits, and when one TPC command corresponds to two closed loop power control process identifiers, the TPC command may be in a form of 2bits +1 bit.
