Method and system of allocating code resources for the High Speed Physical Downlink Shared Channel HS-PDSCH in WCDMA communications.

摘要

A method and system of allocating code resources for a high speed physical downlink shared channel are disclosed. The method includes: recording usage states for code resources of a system at a base station; allocating, by the base station, code resources with idle state to the HS-PDSCH when the code resources of the HS-PDSCH are not enough. The system includes a radio network controller and a base station; the radio network controller is configured to allocate code resources of a system to corresponding channels, and inform the usage states of the code resources to the base station. When there is a shortage of code resources for HS-PDSCHs, idle code resources in a same code tree may be temporarily allocated to the HS-PDSCHs. Thus, the shortage of code resources is moderated to some extent, and the efficiency of code resources in the overall system is raised.
