Wireless resource allocation method, wireless resource allocation device, and communication system

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.

主权项

1. A wireless resource allocation method, comprising:
switching configurations between neighboring cells when different configurations are used in the neighboring cells in a cellular communication system in which a plurality of configurations different in an uplink allocation and a downlink allocation of sub frames in a radio frame are defined; rearranging an order of the plurality of configurations in an ascending order of number of downlink sub frames and in a descending order of number of uplink sub frames; and avoiding interference between the neighboring cells in sub frames in which the uplink and the downlink are mismatched between the neighboring cells whose configurations are switched in the switching.
