Abstract

An embodiment of the invention provides an uplink feedback method of a high speed dedicated physical control channel (HS-DPCCH), a terminal and a base station thereof. The method comprises the following steps: receiving uplink feedback triggering information; carrying out uplink sending according to the uplink feedback triggering information, wherein the uplink sending comprises that uplink HS-DPCCH feedback is performed according to a received uplink feedback resource. In the embodiment of the invention, the feedback of UE for downlink HS-DSCH (high speed downlink shared channel) data is realized and then a base station can determine whether to retransmit the sent data according to the feedback. A blind retransmission mode in the prior art is avoided. By using the method of the invention, a utilization rate of a downlink HS-DSCH resource is increased and a downlink throughput is increased too.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to an uplink feedback method, terminal and base station of a high speed dedicated physical control channel (HS-DPCCH). Background technique

[0002] In the R7 version of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) WCDMA (Wide-band Code Division Multiple Access, Wideband Code Division Multiple Access), in order to improve the UE's cell-forward access channel (CELL- The downlink data transmission rate in FACH: Forward AccessChannel) state and cell-paging channel (CELL-PCH: Paging channel) state introduces the new feature of enhanced CELL-FACH. With this feature, the UE can receive downlink data from a High Speed ​​Downlink Shared Channel (HS-DSCH: High Speed ​​Downlink Shared Channel) in the CELL-FACH and CELL-PCH states.

[0003] However, when the base station sends downlink data to the UE through the HS-DSCH channel, currently only b...
