Communication control apparatus, communication control method, radio communication apparatus, and radio communication method
First Claim
1. A communication control apparatus comprising:
- circuitry configured tocommunicate 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; 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 an 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 the reception signal, to not exceed a threshold in order to support the radio communication apparatus in removing self-interference due to leakage of the transmission signal from the reception signal.

Abstract
[Object] To be able to utilize radio resources more efficiently in the environment where a small cell is operated.
[Solution] Provided is a communication control apparatus including: a communication unit 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; and a control unit configured to, 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 in the radio communication apparatus, adjust a power ratio between a reception signal and a transmission signal in order to support the radio communication apparatus in removing self-interference due to a sneak of the transmission signal from the reception signal.

9. 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.

15. 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. - View Dependent Claims (16, 17)

18. A communication control method that is performed when either a reception on a radio backhaul link and a transmission on an access link, or a reception on the access link and a transmission on the radio backhaul link are simultaneously executed on an identical channel of a radio communication apparatus, the radio communication apparatus being connected to a base station via the radio backhaul link and is connected to one or more terminals via the access link, the method comprising:
-
transmitting, by circuitry of a communication control apparatus, a transmission signal of the communication control apparatus, and receiving, by the circuitry, the reception signal of the communication control apparatus, and, adjusting, by the circuitry, a power ratio, which is a ratio of a power of a transmission signal to a power of a reception signal, to not exceed a threshold, such that the radio communication apparatus is able to remove self-interference due to leakage of the transmission signal from the reception signal by performing self-interference cancellation. - View Dependent Claims (19)
