Abstract

The present invention provides a method and device for allocating code offsets, wherein the method includes: the RNC divides the access time of the user equipment into one or more groups of access time that do not overlap each other; wherein each group of access time The time includes one or more time slots; the RNC allocates the corresponding code offset τDPCH according to the type of the user equipment; wherein, the τDPCH is located in the above time slot in the above access time of the user equipment. Through the present invention, the problem that the method of aligning the uplink subframe boundary in the related art has a great influence on the performance of the downlink is solved, so that the uplink subframe boundary of the TDM UE arriving at the Node B is aligned as much as possible, the interference between TDMUEs is reduced, and the system is improved. throughput without seriously affecting downlink performance.

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), interference among UEs will seriously reduce the throughput performance of the system. High Speed ​​Uplink Packet Access (HSUPA for short) is a technology for enhancing the uplink transmission capability of the WCDMA system. The HSUPA technology includes a shorter Transmission Time Interval (Transmission Time Interval, referred to as TTI), a base station (Node B) based scheduler and a Hybrid Automatic Retransmission Request (Hybrid Automatic Retransmission Reques...
