Abstract: Provided are an array selection method, a terminal, a network device, and a storage medium. The method comprises: sending assistance information to a network device, wherein the assistance information comprises at least one of the following: identifier information of an optimal reference signal required for uplink transmission, and an array-based maximum power reduction (P-MPR) value corresponding to one or more arrays of a terminal when a maximum power exposure (MPE) event occurs; and receiving indication information sent by the network device on the basis of the assistance information, wherein the indication information is used for indicating an array used by the terminal for subsequent uplink transmission, or for indicating that the terminal performs new uplink beam scanning. The embodiments of the present application avoid the uplink coverage loss caused by an MPE issue.

Abstract: An uplink power control method, a terminal, and a network device are provided, which relates to the field of communications, and is to solve a problem that the terminal cannot reach a maximum transmission power for codebook-based or non-codebook-based uplink multi-antenna transmission in related technologies. The method includes: obtaining an uplink precoding indication; and controlling a value of an uplink transmission power determined according to a power control procedure to remain unchanged, in a case that the uplink precoding indication corresponds to a target precoding indication. Based on the solution of the present disclosure, it is ensured that the maximum uplink transmission power can be reached under part of precoding indications, the coverage of uplink transmission can be improved, and it is not required that all antennas of the terminal can reach the maximum transmission power, thereby reducing the cost.
