Macro diversity method, system and device using multi-community associated detection method

Abstract

The invention discloses a macro diversity method, a system and equipment of a united inspection method by using multi-cells, being used for transmitting the data of an uplink transmission block and comprising the following steps: chip grade inspection data of user equipment acquired through united inspection in varied cells are uploaded to a wireless network controller; macro diversity user equipment is confirmed by the wireless network controller according to the uploaded uplink chip grade inspection data and a user equipment macro diversity link is established; and the macro diversity link of the data of the transmission block acquired through the united inspection of the user equipment is maintained according to the configuration of the wireless network controller and the uplink chip grade inspection data. The user data of adjacent cells obtained through the united inspection are directly sent to an upper grade which carries out dispreading and combination by the macro diversity method, the system and the equipment of the invention, thus omitting the process of establishing, managing and maintaining the transmission channels of varied users respectively between a base station and the controller of the base station, not only reducing the process of management and maintenance but also greatly saving resources for maintenance.

Description

Macro-diversity method, system and equipment using multi-cell joint detection method technical field The present invention relates to the technical field of mobile communication, in particular to a method, system and equipment for macro-diversity uplink data by using a multi-cell joint detection method in a time-slot code division multiple access system. Background technique In the CDMA (CodeDivisionMultipleAccess, code division multiple access) mobile communication system, because there is a certain correlation between each user signal, MAI (Multiple Access Interference, multiple access interference) has become a major interference of the broadband CDMA system . The traditional signal separation method of CDMA system treats MAI as noise, and regards the signal separation of a single user as an independent process, that is, single user detection technology. This detection method leads to a severe degradation of the signal-to-noise ratio, limiting the capacity of the syste...
