Abstract
Disclosed are a base station, a wireless communication terminal, a wireless communication system, and a wireless communication method. The base station can be used in coordinated multi-point transmission and comprises: a channel quality obtaining unit for obtaining uplink channel quality between a user equipment and a coordinated base station; a channel quality determination unit for comparing the obtained uplink channel quality with a quality threshold to determine whether the uplink channel quality is good or bad; a feedback control unit for determining, according to a determination result, whether to allow the user equipment to feed back channel state information to the corresponding coordinated base station; and a sending unit for sending information, about how to feed back the channel status information, to the user equipment. When the determination result is that the uplink channel quality is better than channel quality represented by the quality threshold, the feedback control unit determines to allow the user equipment to feed back the channel status information to the corresponding coordinated base station; when the determination result is that the uplink channel quality i…
