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

无线通信系统（1）具有无线终端（UE） 无线基站（BS1），其对应于来自无线终端（UE）的反馈，向无线终端（UE）发送无线信号（RS1）。 以及与无线终端（UE）的反馈相对应的无线电信号（RS2）到无线电终端（UE）的无线电基站（BS2），其频率和时间与无线电 信号（RS1）被发送。 在无线基站（BS1）中使用一个发送天线发送无线信号（RS1）的情况下，无线终端（UE）省略对无线基站（BS1）的反馈。
