Patent ID: 8817688

Claim:
A radio relay device configured to relay data transmitted and received by a first radio communication device and a second radio communication device in a radio communication system in which each of communication time frames segmented on a time axis is provided, by time sharing, with a downlink time period for transmitting data from the first radio communication device to the second radio communication device, and an uplink time period for transmitting data from the second radio communication device to the first radio communication device, the radio relay device comprising: a first transceiver configured to perform first transmission and reception of receiving data from the first radio communication device in the downlink time period and transmitting data to the first radio communication device in the uplink time period, the first transmission and reception using a predetermined frame format; a second transceiver configured to perform second transmission and reception of transmitting data to the second radio communication device in the downlink time period and receiving data from the second radio communication device in the uplink time period, the second transmission and reception using the predetermined frame format; and a controller configured to control the first transmission and reception as well as the second transmission and reception, wherein the controller performs first control of causing execution of the first transmission and reception and suspending of the second transmission and reception during the downlink time period and the uplink time period which are included in a same communication time frame, and second control of causing execution of the second transmission and reception and suspending of the first transmission and reception during the downlink time period and the uplink time period which are included in a same communication time frame.
