Problems solved by technology

If the 6×1 configuration is to be completed as shown in the figure, there will always be PSCs of three cells that are continuous with each other. Due to the existence of the multipath environment of wireless propagation, the collision of PSCs between cells cannot be avoided.
When the user terminal performs cell search, due to the multipath interference between the primary synchronization codes of three consecutive cells, the time slot synchronization is affected, thereby affecting the normal operation of the WCDMA system

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039]The present invention provides a method for configuring synchronous channels of six cells in a six-sector single-carrier frequency structure, including: firstly, establishing a corresponding relationship between each cell and a time offset parameter, and selecting any two consecutive time offsets in the corresponding relationship The parameters correspond to two adjacent cells in the base station, and four mutually spaced time offset parameters are selected to correspond to the other four cells in the base station, and are not adjacent to the first of the two continuous time offset parameters; The step is to generate the corresponding relationship between each cell of the base station and the time offset parameter by the operation and maintenance center, that is, the operation and maintenance center provides a configuration scheme for synchronous channels of a gro...

Abstract

This invention relates to collocation method for the synchronous channels of 6 areas in a 6 fan region single carrier structure including: A, setting up a corresponding relation of the areas with time deviation parameters, selecting two continuous time deviation parameters to correspond two adjacent regions in the base station , selecting four inter-distance time deviation parameters to correspond the other four areas in the base station and not adjacent to said two continuous time deviation parameters, B, determining the primary synchronous codes of the synchronous channels based on the corresponding relation.

Description

technical field [0001] The invention relates to a configuration method of a synchronous channel in a mobile communication system, in particular to a configuration method of a synchronous channel of six cells in a six-sector single-carrier frequency structure in a wideband code division multiple access system. Background technique [0002] Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) communication system adopts an asynchronous method, and strict synchronization is not required between base stations. After the mobile terminal is turned on, it needs to perform cell search to realize the communication between the mobile terminal and the network equipment including the frequency domain. , Time domain, and code domain synchronization. Synchronization in the time domain is achieved through a synchronization channel. [0003] A synchronization channel (SCH, Synchronization Channel) is a downlink used for cell search. The SCH includes two s...
