User Equipment UE and Channel Quality Measurement Method

A channel quality measurement method, used in a user equipment (UE), wherein the UE comprises a baseband chip, at least two transmit antennas, and a controller connected to the at least two transmit antennas, and wherein the method comprises:

• obtaining, by the controller, a signal sending policy, wherein the signal sending policy is a policy pre-agreed on by the UE and a base station, wherein the signal sending policy comprises sending sounding reference signals (SRSs) to the base station in a preset order by using n transmit antennas of the at least two transmit antennas, and wherein n is an integer greater than or equal to 1;
• sequentially selecting, by the controller and in the preset order, the n transmit antennas from the at least two transmit antennas;
• and
• sequentially sending, by the baseband chip, the SRS signals to the base station by using the n transmit antennas selected by the controller, wherein the base station performs channel quality measurement based on the received SRS signals.

A non-transitory computer readable medium having program instructions stored thereon which, wherein when executed by at least one processor, cause the at least one processor to perform operations including:

• obtaining, by a user equipment (UE), a signal sending policy, wherein the signal sending policy is a policy pre-agreed on by the UE and a base station, wherein the signal sending policy comprises sending sounding reference signals (SRSs) to the base station in a preset order by using n transmit antennas of at least two transmit antennas of the UE, and wherein n is an integer greater than or equal to 1;
• sequentially selecting, by the UE and in the preset order, the n transmit antennas from the at least two transmit antennas of the UE;
• and
• sequentially sending, by the UE, the SRS signals to the base station by using the n transmit antennas selected by the UE, wherein the base station performs channel quality measurement based on the received SRS signals.
