Embodiment Construction

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Please refer to figure 1 , the embodiment of the present invention provides a dynamic scheduling system for code resources, which dynamically adjusts the number of HS-PDSCH code channels in a cell through NodeB to achieve the purpose of dynamically scheduling code resources, which includes: RNC 100 and NodeB 200,

[0036] The RNC 100 includes a downlink code resource allocation module 20, which is used for the RNC to pre-allocate common channel code resources to the cells of the NodeB, and to allocate code resources according to accessed users; ...

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...
