A process according to multi-antenna transmission method and a terminal and a base station of the sounding reference signal

The present invention discloses a multi-antenna transmission method and a terminal and a base station of the sounding reference signal, eNB transmitting a new SRS signaling apparatus performs transmit antenna set of wheels made of port information and / or for indicating this to the UE the UE RS SRS transmission scheme and transmits this manner the required control signaling, UE transmits SRS SRS transmission using the above-described embodiment, eNB according to the SRS estimated channel information and the precoding matrix is ​​calculated and sent. The present invention can overcome the number of reception antennas of the UE is greater than the number of transmission ports and downlink configuration port is greater than 2, eNB does not match the radio channel issues among all UE antennas and base station antenna according to the downlink precoding uplink channel matrix calculation; and UE is available for transmission when the number is greater than the number of transmission antenna ports, it is difficult to completely get eNB UE to the eNB all antenna radio channel condition so that the problem can not be transmitted through the PUSCH optimal antenna or antenna group.
