Abstract:
To efficiently transmit a sounding reference signal. One or more downlink BWPs are configured in a serving cell, one or more uplink BWPs are configured in a serving cell, each BWP of the one or more downlink BWPs is identified by a downlink BWP index, each BWP of the one or more uplink BWPs is identified by the uplink BWP index, and in a case that one of the one or more downlink BWPs configured is activated in a serving cell, one of the one or more uplink BWPs configured is activated in a serving cell, and an SRS transmission in one or more serving cells of a plurality of the serving cells is triggered, the SRS for the BWP indicated by the uplink BWP index activated in the serving cell activated is transmitted.
