Abstract

An uplink data transmission method, a user equipment, and a readable storage medium are provided. The method includes: receiving DCI, wherein the DCI includes a sounding reference signal resource indication field and a precoding information field, the sounding reference signal resource indication field includes indication information of two or more transmission beams corresponding to to-be-transmitted uplink data, and the precoding information field includes transmission precoding matrix indication information corresponding to each of the two or more transmission beams; determining a transmission precoding matrix corresponding to each transmission beam based on the transmission precoding matrix indication information corresponding to the transmission beam; and transmitting uplink data based on the transmission precoding matrix corresponding to each transmission beam. By the method, the transmission precoding matrices corresponding to multiple transmission beams are indicated in DCI, thereby improving reliability of uplink data transmission.
