RADIO COMMUNICATION SYSTEM, RELAY STATION, AND RELAY METHOD
A wireless communication system is a wireless communication system including a base station that transmits and receives a signal to and from a terminal, and a relay station that relays a signal between the base station and the terminal, in which the base station includes a scheduling function unit that determines a schedule of transmission and reception of signals to and from a plurality of terminals 20 , and transmits schedule information indicating the determined schedule to the relay station, and the relay station includes a schedule information acquisition unit that acquires the schedule information from the base station, and a beam control unit that specifies a terminal being a transmission destination based on the schedule information, and controls a beam used for relay for each terminal specified as a transmission destination based on a beam number specified for each terminal in advance.
1 . A wireless communication system comprising:
a base station that transmits and receives a signal to and from a terminal; and
a relay station that relays a signal between the base station and the terminal,
wherein
the base station includes a scheduling function circuitry that determines a schedule of transmission and reception of signals to and from a plurality of terminals 20 , and transmits schedule information indicating the determined schedule to the relay station, and
the relay station includes:
a schedule information acquisition circuitry that acquires the schedule information from the base station, and
a beam control circuitry that specifies a terminal being a transmission destination based on the schedule information, and controls a beam used for relay for each terminal specified as a transmission destination based on a beam number specified for each terminal in advance.
2 . The wireless communication system according to claim 1 , wherein
the relay station further includes a relay function control circuitry that controls whether to validate a function of relaying a signal between the base station and the terminal based on the schedule information.
3 . The wireless communication system according to claim 2 , wherein
the relay function control circuitry specifies either or both of a time resource and a frequency resource of a signal which is a signal relayed by the relay function control circuitry itself and transmitted or received to or from the terminal based on the schedule information, and validates a function of relaying a signal between the base station and the terminal when either or both of the specified time resource and frequency resource are used.
4 . A relay station that relays a signal between a base station and a terminal, the relay station comprising:
a schedule information acquisition circuitry that acquires schedule information from the base station; and
a beam control circuitry that specifies a terminal being a transmission destination based on the schedule information, and controls a beam used for relay for each terminal specified as a transmission destination based on a beam number specified for each terminal in advance.
5 . A relay method executed by a relay station that relays a signal between a base station and a terminal, the relay method comprising:
acquiring schedule information from the base station; and
specifying a terminal being a transmission destination based on the schedule information, and controlling a beam used for relay for each terminal specified as a transmission destination based on a beam number specified for each terminal in advance.
