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. The time interval at which the radio terminal (UE) performs the feedback to the radio base station (BS1) is longer than the time interval at which the radio terminal (UE) performs the feedback to the radio base station (BS2).
Claims15
A radio communication system comprising:
- a radio terminal;
- a first radio base station configured to transmit a first radio signal to the radio terminal in accordance with feedback from the radio terminal;
- and
- a second radio base station configured to transmit a second radio signal to the radio terminal in accordance with feedback from the radio terminal, at the same frequency and time as the first radio signal, wherein
- a time interval at which the radio terminal provides the feedback to the first radio base station is longer than a time interval at which the radio terminal provides the feedback to the second radio base station.
A radio terminal comprising:
- a receiver configured to receive a first radio signal from a first radio base station and to receive a second radio signal from a second radio base station, at the same frequency and time as the first radio signal;
- and
- a transmitter configured to transmit feedback to the first radio base station and the second radio base station, wherein
- a time interval at which the transmitter provides the feedback to the first radio base station is longer than a time interval at which the transmitter provides the feedback to the second radio base station.
A radio communication system comprising:
- a first radio base station configured to transmit a first radio signal to a radio terminal in accordance with feedback from the radio terminal;
- and
- a second radio base station configured to transmit a second radio signal to the radio terminal in accordance with feedback from the radio terminal, at the same frequency and time as the first radio signal, wherein
- one of the first radio base station and the second radio base station instructs the radio terminal to set a time interval for providing the feedback to the first radio base station to be longer than a time interval for providing the feedback to the second radio base station.
A radio communication method comprising the steps of:
- transmitting a first radio signal to a radio terminal from a first radio base station in accordance with feedback from the radio terminal;
- and
- transmitting a second radio signal to the radio terminal from a second radio base station in accordance with feedback from the radio terminal, at the same frequency and time as the first radio signal, wherein
- a time interval at which the radio terminal provides the feedback to the first radio base station is longer than a time interval at which the radio terminal provides the feedback to the second radio base station.
