Abstract:
1. A method for transmitting sounding reference signals by using multiple antennas, comprising: in an LTE-advanced system with uplink multiple antennas where uplink SU-MIMO is supported, an e-Node-B configuring a period of transmitting sounding reference signals periodically for a user equipment for transmitting the sounding reference signals over each antenna respectively, wherein the periods of transmitting sounding reference signals periodically configured by the e-Node-B are different when the user equipment has two antennas, and the periods of transmitting sounding reference signals periodically configured by the e-Node-B are all different or partially the same when the user equipment has more than two antennas; and the user equipment transmitting uplink sounding reference signals with a corresponding period of transmitting sounding reference signals periodically over each antenna according to the configuration of the e-Node-B.
