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.
