Abstract

The invention provides a code deviation distribution method and apparatus. The method includes the following steps that: an RNC equally divides access time of user equipment into one or more groups of access time which are not overlapped with each other, wherein each group of access time includes one or more time slots; and the RNC distributes corresponding code deviation Tau DPCHs according to the types of the user equipment, wherein the Tau DPCHs are located at the time slots of the access time of the user equipment. With the code deviation distribution method and apparatus of the invention adopted, the problem of serious influence of an uplink sub frame boundary alignment method on the performance of downlinks can be solved, such that alignment with uplink sub frame boundaries when the TDM UE arrives at a Node B can be realized as much as possible, and interference between the TDMUE can be reduced, and system throughput can be improved, and at the same time, the performance of the downlinks will not be seriously affected.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for allocating code offsets. Background technique [0002] In a Wideband Code Division Multiple Access (WCDMA for short) wireless communication network, even user equipment (User Equipment, UE for short) in the same cell are not orthogonal to each other. Interference exists. When a large number of UEs access the system in a code division multiple access (Code Division Multiplexing, CDM for short) manner, the interference among UEs will seriously reduce the throughput performance of the system. High Speed ​​Uplink Packet Access (HSUPA for short) is a WCDMA system enhancement technology for uplink transmission capability. The HSUPA technology includes a shorter transmission time interval (Transmission Time Interval, referred to as TTI), a scheduler based on a base station (Node B) and a hybrid automatic retransmission request (Hybrid Automatic Retransmission...
