PROBLEM TO BE SOLVED: To avoid inter-other route interference without reducing transmission speed efficiency in a full duplex relay system in P-MP communication.SOLUTION: A radio relay device performs full duplex relay of each of signals on routes between a radio base station and a plurality of radio terminal stations that perform P-MP communication. The radio relay device comprises inter-other route interference cancelling means that, when full duplex relay of a signal A on its route is performed among signals transmitted destined to each radio terminal station by time division by the radio base station, generates a cancelling signal from a signal B on another route before the signal A by one, and cancels inter-other route interference by applying the cancelling signal to the signal A.SELECTED DRAWING: Figure 1 |
