Time division duplex (TDD) cross interference grouping management method and base station

The invention provides a time division duplex (TDD) cross interference grouping management method. The method includes the steps of carrying out grouping on a plurality of areas through adoption of the interference coordination technology based on grouping and executing the following steps to the plurality of areas which belong to the same group: (1) selecting at least one interference isolation area from the plurality of areas in the same group, and (2) controlling at least one interference isolation area, carrying out isolation on the other areas among the plurality of areas in the same group, and dividing the other areas into a plurality of groups, wherein each group contains at least one area, and the plurality of groups adopt the same or different TDD uplink and downlink subframe proportional allocation parameters. The invention further provides a base station. The TDD cross interference grouping management method can carry out isolation and regrouping on the other areas in the same group through utilization of a part of areas, and consequently the areas in the different groups after being regrouped can use different TDD uplink and downlink subframe proportions to carry out data transmission, and then cross interference is effectively controlled.
