摘要

In the presence of an assignment of the downlink resource block to the UE2-1, the eNB1-1 requests the UE2-1 to transmit SRS in the frequency band corresponding to the comb 0, and in the absence of the assignment of the downlink resource block to the UE2-1, the eNB1-1 requests the UE2-1 to transmit SRS in the frequency band corresponding to the comb 1. The UE2-1 transmits the SRS of the frequency band corresponding to the request.
