Abstract
The invention provides an uplink and downlink slot time resource configuration method based on interference perception in a TDD system, which is applied to a communication network comprising a source base station, a target base station, as well as a user terminal in the source base station and a user terminal in the target base station, and the method comprises: judging whether the base station-to-base station interference is larger than a preset threshold value or not, if yes, canceling the uplink and downlink slot time resource configuration, and if no, continuously executing the next step; judging whether the interference measurement of the target base station on the user terminal in the source base station is larger than a preset threshold value or not, if no, executing the uplink and downlink slot time resource configuration, and if yes, executing the next step; judging whether the interference measurement of the source base station on the user terminal in the target base station is larger than a preset threshold value or not, if yes, canceling the uplink and downlink slot time resource configuration, and if no, executing the uplink and downlink slot time resource configuration. By the information interaction between the base stations, the flexible configuration of uplink and downlink slot time resources is realized, and the crossing slot time interference problem brought by the flexible configuration of the uplink and downlink slot time resources in different network structures is solved.
