Title:
TIMING CONTROL OF RELAY STATION CONTROLLED BY NETWORK
Document Type and Number:
WIPO Patent Application WO/2024/069993
Kind Code:
A1
Abstract:
A communication control device according to the present invention controls, by time-division duplexing, a communication network comprising a wireless access network, a communicator capable of communicating with the wireless access network, and a relay station that relays downlink communication and uplink communication between the wireless access network and the communicator under the control of the wireless access network. The communication control device comprises at least one processor that controls, by using a timing control unit, an uplink transmission timing of the relay station for the wireless access network in the relay of the uplink communication so that the uplink transmission timing is after a timing obtained by adding an uplink processing delay of the relay station of the relay to an uplink reception timing of the relay station from the communicator of the relay (fig. 3).
