Abstract:
[Object] To realize a mechanism for protecting a terminal connected to a small cell against harmful interference when idea of full-duplex radio communication is applied to a radio backhaul link and an access link of the small cell.[Solution] Provided is a communication control apparatus including: a control unit configured to, when transmission from a base station to a master terminal on a radio backhaul link and transmission from the master terminal to a radio communication apparatus on an access link are executed on the same channel at the same time, control transmission power of the base station and transmission power of the master terminal so that the radio communication apparatus is able to cancel a second received signal due to transmission on the radio backhaul link, the second received signal interfering with a first received signal on the access link, using an interference cancellation technique based on a received power difference.
