Abstract:
1. A communication device incorporated in a base station for allocating a plurality of frequency bands each to different terminals to enable wireless communication, the communication device comprising: a power booster to increase transmission power of a common pilot signal or transmission power of one of the plurality of frequency bands or both thereof, depending on a handover request from a terminal requesting a handover from a source base station to a target base station; and a frequency band allocator to allocate the frequency band with the increased transmission power for transmission of a data signal from the source base station to the terminal requesting the handover; wherein the power booster increases the transmission power of one of the plurality of frequency bands when the handover request designates the communication device as the source base station of the handover, and wherein the power booster increases the transmission power of the common pilot signal when the handover request designates the communication device as the source base station of the handover, but holds the transmission power of the common pilot signal when the handover request designates the communication device as the target base station of the handover.
