Communication control apparatus, communication control method, radio communication apparatus, and radio communication method

A communication control apparatus comprising:

• circuitry configured to
• communicate with a radio communication apparatus being connected to a base station via a radio backhaul link and being connected to one or more terminals via an access link,
• determine, based on at least one of an amount of traffic to be processed by the radio communication apparatus and a number of the one or more terminals, whether to increase a capacity of the radio communication apparatus,
• when the capacity of the radio communication apparatus is determined to be increased, allow the radio communication apparatus to execute a reception and a transmission on an identical channel simultaneously, and,
• when a reception on the radio backhaul link and a transmission on the access link, or a reception on the access link and a transmission on the radio backhaul link are executed on the identical channel simultaneously in the radio communication apparatus, adjust a power ratio, which is a ratio of a power of a transmission signal to a power of a reception signal, in order to support the radio communication apparatus in removing self-interference due to leakage of the transmission signal from the reception signal.

A communication control apparatus comprising:

• circuitry configured to
• communicate with a base station via a radio backhaul link and to communicate with one or more terminals via an access link;
• when a reception on the radio backhaul link and a transmission on the access link, or a reception on the access link and a transmission on the radio backhaul link are executed on an identical channel simultaneously, perform self-interference cancellation to remove self-interference due to leakage of a transmission signal from a reception signal;
• and
• adjust a power ratio representing a ratio of a power of the transmission signal to a power of the reception signal, the power ratio being adjusted in order to support the removing of the self-interference, wherein the power ratio is adjusted in such a way that the power ratio does not exceed a threshold.
