CODE CHANNEL RESOURCE ALLOCATION METHOD OF HIGH SPEED UPLINK PACKET ACCESS IN TD-SCDMA SYSTEM

摘要

A code channel resource allocation method of High Speed Uplink Packet Access in TD-SCDMA system involves the following steps: UE initiates an uploading authorization request to Node B through E-RUCCH or E-PUCH; after receiving the request, the Node B designates the spread spectrum code channel, code channel power and time slot for the UE using the scheduling algorithm according to the uploading information packet size, radio resource and UE service level condition in the message, and transmits to the UE through E-AGCH; the UE selects the appropriate modulation mode and transmitting packet size according to the spread spectrum code channel, time slot and code channel power transmitted through the E-AGCH; and the UE transmits the data to the Node B using the rate matching algorithm in the spread spectrum code channel and time slot allocated by the Node B. The present invention could realize the flexible resource allocation, the high availability and could avoid the disadvantageous influence to other UE uplink service because of false despreading.
