INTERFERENCE MEASUREMENT METHOD AND APPARATUS FOR CONTROLLING INTER-CELL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM

摘要

The present disclosure relates to an interference measurement method and apparatus for controlling inter-cell interference in a Time Division Duplex (TDD) radio communication system and, in particular, to a technology for a base station to configure a radio frame capable of controlling interference with adjacent base stations and to measure interference based on the radio frame configured as such. In an embodiment of the present disclosure, the first base station sends the second base station the first radio frame configuration information and the second radio frame configuration information including a subset of uplink subframes of the first radio frame configuration. The second base station configures the intersection of uplink subframes of the first and second radio frame configurations into the first interference measurement subframe set and difference of the sets of the subframes of the respective first and second radio frame configurations into the second interference measurement subframe set. The second base station measures uplink interference signals of the neighbor cell during the first interference measurement subframe set and the downlink interference signal of the neighbor cell during the second interference measurement set and transmits the measurement result to the first base station. Through this method, the base station is capable of predicting uplink coverage of the neighbor cell during the first interference measurement subframe set and the downlink coverage of the neighbor cell during the second interference measurement subframe set for controlling inter-cell interference.
