SHORT-TERM INTERFERENCE REDUCTION IN ASYNCHRONOUS WIRELESS NETWORK

PROBLEM TO BE SOLVED: To provide a technique for short-term interference reduction in an asynchronous wireless communication network.SOLUTION: Frequency resources (control resource and pilot resource) are prepared to transmit an interference reduction request and a pilot between asynchronous wireless communication networks. A first station (for example, a terminal) transmits a request to reduce interference to at least one interference station, on the prepared control resource. The first station receives a pilot transmitted from each interference station on the prepared pilot resource. The prepared resources are combined with a data resource. Based on the pilot, the first station estimates reception signal quality of the data resource. After the interference station reduces interference, the first station receives data transmitted by a second station (for example, a service provision base station) on the data resource.
