HIGH SPEED UPLINK PACKET ACCESS METHOD IN MULTI-CARRIER TD-SCDMA SYSTEM

摘要

A high speed uplink packet access method and system used for multi-carrier TD-SCDMA system are disclosed. The method comprises the following steps: carrier resources on which the scheduling enhanced physical uplink channels are configured are allocated to user equipment; the enhanced absolute grant channel and the enhanced HARQ acknowledgement indicator channel are configured on the allocated carrier resources; the data from the enhanced dedicated transport channel are mapped through media access control layer onto the enhanced dedicated channel and further mapped onto the scheduling enhanced physical uplink channel; the scheduling enhanced physical uplink channels are granted to the user equipment through the enhanced absolute grant channel, so as to transmit the data from the enhanced dedicated transport channel to the base station; the base station feeds back the status information about receiving the data from the enhanced dedicated transport channel to the user equipment through the enhanced HARQ acknowledgement indicator channel. With the present invention, the carrier resources in multi-carrier TD-SCDMA system are utilized sufficiently and thus the cell uplink transport throughput is improved.
