Uplink reference signal sending method and apparatus, base station, and user equipment
This application provides an uplink reference signal sending method and apparatus, a base station, and user equipment (UE). The method includes: configuring, by the base station, M pieces of uplink reference signal resource information for the UE; and sending, by the base station, the M pieces of uplink reference signal resource information to the UE, so that the UE sends uplink reference signals based on different uplink reference signal resource information with different beamforming gains. A path loss is compensated for by using a beamforming technology. In addition, the base station configures the M pieces of uplink reference signal resource information for the user equipment UE, so that the UE sends the uplink reference signals by using different relatively uplink reference signal resource information based on different beamforming gains. Therefore, uplink reference signal sending efficiency is improved.
