WIRELESS COMMUNICATION SYSTEM, WIRELESS TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD

WIPO Patent Application WO/2010/137665

A1

A wireless communication system (1) has: a wireless terminal (UE); a wireless base station (BS1) which transmits wireless signals (RS1) to the wireless terminal (UE) corresponding to the feedback from the wireless terminal (UE); and a wireless base station (BS2) which transmits, corresponding to the feedback from the wireless terminal (UE), wireless signals (RS2) to the wireless terminal (UE) at the frequency and time identical to the frequency and time at which the wireless signals (RS1) are transmitted. In the case where one transmitting antenna is used for the transmission of the wireless signals (RS1) in the wireless base station (BS1), the wireless terminal (UE) omits the feedback to the wireless base station (BS1).
