Example Embodiment
[0025] The embodiment of the present invention provides a physical cell identity planning method and device, which can avoid PCI conflicts and reduce interference between reference signals.
[0026] See figure 1 , The physical cell identity planning method in the embodiment of the present invention includes:
[0027] 101. Obtain interference information between base stations;
[0028] In this embodiment, for base stations that need to plan PCI, first calculate the mutual interference information between the base stations.
[0029] 102. Allocate different Vshift groups to each base station according to the interference information, and allocate a corresponding Vshift in the Vshift group of the base station to a cell in each base station;
[0030] After the interference information between the base stations is obtained, different Vshift groups can be allocated to each base station according to the interference information, and the corresponding Vshift in the Vshift group of the base stati...
