1. An uplink transmission method, comprising: instructing, by a base station, a User Equipment (UE) to send Sounding Reference Signals (SRSs) corresponding to N groups of SRS resources, wherein each group of SRS resources comprises one or more SRS resources, and N is a positive integer greater than 1; receiving, by the base station, the SRSs sent by the UE;
determining, by the base station, X groups of uplink scheduling information; wherein each group of uplink scheduling information corresponds to one of the N groups of SRS resources, and
X is a positive integer greater than land less than N, or X is a positive integer greater than 1 and equal to N;
sending, by the base station, the X groups of uplink scheduling information to the UE for the UE performing uplink signal transmission according to the X groups of uplink scheduling information; and
sending, by the base station, SRS resource set indication information to the UE, wherein the SRS resource set indication information indicates SRS resource sets corresponding to the X groups of uplink scheduling information.
