UPLINK TRANSMISSION METHOD AND APPARATUS

WIPO Patent Application WO/2020/035072

A1

The present invention provides an uplink transmission method and apparatus, for use in improving the flexibility of uplink scheduling. The method comprises: a base station instructs a UE to send SRSs corresponding to N groups of SRS resources, each of the N groups of SRS resources comprising one or more SRS resources; N being a positive integer; the base station receives the SRSs sent by the UE to determine X groups of uplink scheduling information, each of the X groups of uplink scheduling information corresponding to one group of SRS resources in the N groups of SRS resources; uplink scheduling information in different groups corresponding to SRS resources in different groups; X being a positive integer greater than one and not greater than N; the base station sends the determined X groups of uplink scheduling information to the UE so that the UE transmits an uplink signal according to the X groups of uplink scheduling information.
