Abstract

The embodiment of the invention provides an optimal configuration method and equipment for a physical cell identifier. The method comprises the following steps: dividing cells to be optimized into a first type of cells and a second type of cells; determining a first primary synchronization sequence (PSS) configuration scheme of the first type of cells; determining a second PSS configuration schemeof the second type of cells according to the first PSS configuration scheme; and determining a physical cell identifier PCI configuration scheme of the cell to be optimized according to the first PSSconfiguration scheme and the second PSS configuration scheme. According to the embodiment of the invention, the configuration efficiency of the PCI can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for optimizing configuration of a physical cell identifier. Background technique [0002] Long Term Evolution (LTE for short) is the core technology of the fourth generation mobile communication network. The LTE network adopts the same-frequency networking, and the Physical Cell Identity (Physical Cell Identity or Physical Cell Identifier, PCI) is used to identify and identify different cells in the network, and it is used as a part of the channel scrambling code input device to perform channel isolation. PCI is composed of Secondary Synchronization Sequence (SSS for short) and Primary Synchronization Sequence (PSS for short). The calculation method of PCI is PCI=3×SSS+PSS, where the value range of SSS is 0 to 167 , the value range of the PSS is from 0 to 2, so there are 504 independent PCIs in the LTE network. Imprope...
