Title:
RADIO RELAY DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/135822
Kind Code:
A1
Abstract:
This radio relay device comprises: a receiving unit that receives signals from a plurality of base stations; a control unit that is connected to a base station having a reception quality of the signal greater than or equal to a certain threshold; and a relay unit that relays a signal between the connected base station and a terminal. The relay unit relays, to the terminal, a signal that is associated with an index and that includes broadcast information and a synchronization signal which is transmitted from the connected base station. The receiving unit receives, from the connected base station, control information indicating a beam to be applied to each resource. The control unit determines, for each resource, a beam to be applied to a relayed signal, on the basis of the control information.
