METHOD FOR UPLINK AND DOWNLINK TIME SLOT RESOURCE ALLOCATION BASED ON INTERFERENCE COGNITION IN TIME DIVISION DUPLEX SYSTEM

摘要

A method for uplink and downlink time slot resource allocation based on interference cognition in a time division duplex system is provided in the present invention. The method is applied to a communication network comprising a source base station, a target base station, a user terminal of the source base station and a user terminal of the target base station. The method comprises the following steps: determining whether the interference between base stations is higher than a predetermined threshold, if yes, cancelling the uplink and downlink time slot resource allocation, if no, executing the next step; determining whether the interference to the user terminal of the source base station from the target base station is higher than a predetermined threshold, if no, allocating the uplink and downlink time slot resource, if yes, executing the next step; determining whether the interference to the user terminal of the target base station from the source base station is higher than a predetermined threshold, if yes, cancelling the uplink and downlink time slot resource allocation, if no, allocating the uplink and downlink time slot resource. With the information interaction between base stations, the flexible allocation of the uplink and downlink time slot resource is realized, and the cross time slot interference problems caused by the flexible allocation of the uplink and downlink time slot resource in different network architectures is solved
