CONTROL STATION, RELAY, TRANSMITTER, COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a control station capable of multi-beam data transmission with a reduced circuit.

SOLUTION: The control station receives, from a transmitter, data transmitted from the transmitter and destined to a receiver present in a beam and transmits the data to a relay forming one or more beams. A cluster is constituted by one or more beams. Correspondence between the receiver and the present beams is retained. The control station includes: by referring to the correspondence, a data distribution unit 203 for distributing the data received from the transmitter to beam-by-beam data on each beam basis; a frame generation unit 204 for generating a frame constituted by the beam-by-beam data corresponding to the beam belonging to an identical cluster; and by defining a transmission frequency in advance for each cluster, a transmission unit 205 for transmitting frames destined to an identical cluster with an identical transmission frequency.
