Title:
無線通信システムにおける直交符号動的割当装置および方法
Document Type and Number:
Japanese Patent JP4546545
Kind Code:
B2
Abstract:
An apparatus, method, and system for dynamically assigning orthogonal codes to different information signals communicated between a Node B and user equipment in a cellular radio communication system in which a fixed number of codes are allocated between dedicated transport channels (DCHs) and high speed downlink shared channels (HS-DSCHs). A radio controller (RNC) allocates a minimum number of codes for HS-DSCH physical channels (HS-PDSCH codes) to the Node B. The Node B determines HS-PDSCH codes that are not currently being utilized and allocates HS-PDSCH codes from the unused codes without having to communicate with the RNC. When the additional HS-PDSCH codes are needed for DCH codes, the Node B reallocates the codes for DCH purposes without reducing the number of HS-PDSCH codes below the allocated minimum.
