Abstract

The invention provides a cell clustering method. The cell clustering method is characterized by comprising the step of calculating isolation between every two adjacent cells in a wireless communication network cell aggregation; the step of setting the isolation threshold value theta and judging whether a boundary exists between the two cells; the step of dividing the cell aggregation in which the boundaries exist between every two adjacent cells into sub-clusters Si in the wireless communication network cell aggregation U, wherein i=1, 2,...,m and the sub-clusters Si meet the formula: U=S1 UpsilonS2 Upsilon...Upsilon Sm; the step of calculating the connectivity among the sub-clusters; the step of setting a connectivity threshold value N and judging whether the sub-clusters need to be combined or not according to the connectivity threshold value N; when the connectivity degree between every two adjacent sub-clusters is larger than the connectivity threshold value N, the two sub-clusters are combined. The limitation tolerance for an interference link is ruled according to the connectivity threshold value among the sub-clusters, and on the premise that the interference among cell base stations is effectively avoided, the requirement for improving the self-adaptability of the cell network service can be improved.

Description

technical field

[0001] The invention relates to a wireless communication network, in particular to a cell clustering method. Background technique

[0002] In a wireless communication network, especially in a Time Division Duplex (TDD) network, since different cells may use different uplink and downlink subframe configurations, adjacent cells may be in different uplink and downlink transmissions on a specific subframe. State, so there will be mutual interference between base stations and user terminals in the network. This kind of uplink and downlink interference will seriously affect the improvement of network performance brought about by service adaptability, and since the transmit power of cell base stations will be significantly greater than that of user terminals, the mutual interference between cell base stations is a TDD sub- One of the first problems to be solved in frame configuration adaptive network.

[0003] In order to effectively suppress the uplink and downli...
