Signal transmission method, terminal device, and network device

A terminal device, comprising:

• at least one processor;
• and
• at least one memory including program code;
• the at least one memory and the program code configured to, with the at least one processor, cause the terminal device to perform a plurality of operations including:
• receiving configuration information sent by a network device, wherein the configuration information is used to indicate a correspondence between first information and one group of power control parameters, the first information indicating a channel state information-reference signal (CSI-RS) resource and the group of power control parameters comprises a value of at least one power control parameter;
• obtaining the first information and second information from the configuration information, the second information indicating a power control parameter of a target uplink signal, wherein the CSI-RS resource indicated by the first information is configured to obtain a beam for transmission of the target unlink signal;
• determining a transmit power of the target uplink signal according to the power control parameter;
• and
• outputting the target uplink signal to the network device according to the transmit power.

A non-transitory computer readable medium comprising program instructions stored thereon that, when executed by a processor of a terminal device, cause the terminal device to perform a plurality of operations including:

• receiving configuration information sent by a network device, wherein the configuration information is used to indicate a correspondence between first information and one group of power control parameters, the first information indicating a channel state information-reference signal (CSI-RS) resource and the group of power control parameters comprises a value of at least one power control parameter;
• obtaining the first information and second information from the configuration information, the second information indicating a power control parameter of a target uplink signal, wherein the CSI-RS resource indicated by the first information is configured to obtain a beam for transmission of the target unlink signal;
• determining a transmit power of the target uplink signal according to the power control parameter;
• and
• outputting the target uplink signal to the network device according to the transmit power.
