Uplink power control method, base station and user equipment
A method includes: sending, by a user equipment (UE), uplink test signaling to transceivers for serving the UE, so that the transceivers calculate receive power of the uplink test signaling by testing the uplink test signaling; receiving, by the UE, the receive power of the uplink test signaling and transmit power of a common reference signal (CRS) from the transceivers; receiving and testing, by the UE, the CRS sent by the transceivers to obtain receive power of the CRS; calculating, by the UE, uplink path losses on paths between the UE and the transceivers according to the receive power of the uplink test signaling, the transmit power of the CRS, and the receive power of the CRS; calculating, by the UE, an aggregate path loss according to the uplink path losses on paths between the UE and the transceivers; and calculating, by the UE, uplink transmit power according to the aggregate path loss.
