摘要： An allocation of wireless resources is performed to avoid interference caused as an uplink and a downlink are mismatched between neighboring cells. When interference at a base station is desired to be reduced, in each portion causing interference at a base station side, an ABS is applied to any one of downlink and uplink sub frames. When interference at a terminal is desired to be reduced, in each portion causing interference at a terminal side, transmission or reception of a terminal is stopped. When both interference at a base station side and interference at a terminal side are desired to be reduced, basically, it is desirable to stop the same portion as when interference between base stations is reduced.

摘要： Inter-cell interference is avoided in a cellular system operated in a TDD scheme. An order of a plurality of configurations are rearranged in the ascending order of the number of downlink sub frames and in the descending order of the number of uplink sub frames, and configurations are switched between neighboring cells according to the rearranged order when different configurations are used in the neighboring cells. Further, an order of at least some configurations is further rearranged so that interference between adjacent configurations is reduced while maintaining the ascending order of the number of downlink sub frames.

摘要： User equipment performs radio communication with a base station over a communication channel formed by aggregating a plurality of component carriers. The user equipment measures a channel quality of the communication channel, and creates a measurement report using a result of the measurement and sends the measurement report to the base station. Each data signal is classified into two or more classes depending on a QoS requirement. The user equipment further receives control information related to a mapping between the plurality of component carriers and the class of each data signal from the base station, and controls at least one of the measurement and the sending of the measurement report, according to a procedure which varies depending on the control information. A base station allocates data to component carriers based on channel quality criteria for different data classifications.
