Abstract

The invention provides a dynamic scheduling method of code resources, comprising the steps: (1) an RNC (radio network controller) distributes public channel code resources to cells of a NodeB in advance; (2) the NodeB acquires the occupying condition of the downlink code channels of the current cells and carries out sorting on usable spreading factor (SF)16 code channels; and (3) the NodeB carries out code channel updating according to the usable SF 16 code channels and marks the code channels for user scheduling of high-speed downlink packet access (HSDPA). The invention also provides a dynamic scheduling system and base station of the code resources. In the method, the base station and the system, the problems and the defects that in the prior art, the adjustment period of the RNC to the number of HS-PDSCH (high-speed physical downlink shared channel) code channels of the cells of the NodeB is longer and the downlink code channel resources are wasted can be overcome, downlink code channel resources are fully and reasonably utilized, the utilization ratio of the downlink code channel resources and the downlink throughput of HSDPA cells are improved, and the overall performance of a network is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically relates to a method, a base station and a system for flexibly and dynamically adjusting downlink code resources in a broadband mobile communication system. Background technique [0002] For the third-generation mobile communication system technology, the downlink code resource is a relatively precious resource, especially in order to improve the system capacity and performance without increasing the cost, it is very important to make full and reasonable use of the code channel resource. The total number of downlink code resources in each cell is fixed, part of which is occupied by the common channel of the cell, and the remaining part is pre-allocated to HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) by RNC (Radio Network Controller, radio network controller). Incoming) users, the rest are allocated to non-HSDPA users, a...
