<p>Disclosed are a method and a device for configuring multi-antenna parameters of a sounding reference signal (SRS), for solving the problem that configuration of multi-antenna SRS parameters cannot be determined in the prior art. The technical solution comprises: a base station notifying, through high-layer signaling, a UE of transmitting a periodic SRS or a non-periodic SRS, SRS transmission parameters comprising a cyclic shift and a frequency comb k TC; and after obtaining the SRS transmission parameters notified by the base station, the UE determining, according to the number of antenna ports for transmitting the SRS and a preset mapping relationship, the SRS transmission parameters at each antenna port. With the technical solution of the present invention, the UE can determine, according to the configured implicit mapping relationship, the SRS transmission parameters at each antenna port, thereby reducing signaling overhead and ensuring configuration flexibility.</p> |
