Patent ID: 8855551

Claim:
A base station, comprising: a baseband unit (BBU), configured to receive uplink signals of a user equipment (UE) from at least one radio frequency (RF) group of multiple RF groups through at least one data channel of multiple data channels, to determine information about the at least one RF group which the uplink signals of the UE are received from and to allocate power of downlink signals of the UE in the multiple RF groups according to the information about the at least one RF group which the uplink signals of the UE are received from to avoid that each of the multiple RF groups needs transmission consumption; wherein, the BBU is configured to connect with the multiple RF groups through the multiple data channels, the multiple RF groups belong to a same cell, an area which each of the multiple RF groups corresponds to in the cell is different from each other and one of the multiple RF groups which each of the multiple data channels corresponds to is different from each other.
