Abstract: The present disclosure relates to channel quality measurement methods and equipment. One example method includes obtaining, by a user equipment (UE), a signal sending policy. The UE comprises a baseband chip, at least two transmit antennas, and a controller connected to the at least two transmit antennas. The signal sending policy is a policy pre-agreed on by the UE and a base station. 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. n is an integer greater than or equal to 1. The UE sequentially selects, in the preset order, the n transmit antennas from the at least two transmit antennas. The UE sequentially sends the SRS signals to the base station by using the n transmit antennas.
