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