Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the prior art has the following disadvantages: for the above method, since the RACH measurement results need to be decoded, processed and forwarded by the RNC, and need to be transmitted at the IUB port, not only the processing resources of the RNC and the IUB are wasted. Port transmission resources, and there is a large delay
At the same time, since the UE does not feed back the RACH measurement results during ...

Embodiment Construction

[0015] The embodiment of the present invention provides a method for reporting feedback information. Through the embodiment of the present invention, the UE carries the CQI feedback value reported to the base station through the MAC-i PDU or HS-DPCCH, realizing the rapid and direct reporting of the CQI feedback value to the base station. It saves RNC processing resources and IUB port transmission resources. At the same time, when the downlink data is frequent or lasts for a long time, the CQI feedback value can also be reported frequently, so that the base station can timely and accurately determine the downlink modulation according to the CQI feedback value. The encoding mode and transmission power are beneficial to improve the success rate of UE downlink receiving HS-DSCH transmission blocks, thereby reducing the number of retransmissions and improving the downlink HS-DSCH transmission efficiency. The base station in the embodiment of the present invention may be an entity su...

Abstract

The embodiment of the invention discloses a method of reporting feedback information, which comprises the following steps: user equipment UE reports channel quality indicator CQI feedback value to a base station, the CQI feedback value is carried by enhanced specialized transmission channel media access control protocol data unit MAC-i PDU or high speed downlink shared channel specialized physical control channel HS-DPCCH. By the embodiment of the invention and the CQI feedback value carried by MAC-i PDU or HS-DPCCH and reported to the base station by UE, the CQI feedback value can be rapidly and directly reach the base station, thereby saving the processing resources of RNC and transmission resources of IUB port and the base station can timely and accurately determine downlink modulation coding mode and transmitting power according to the CQI feedback value.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, and in particular to a method, system and device for reporting feedback information. Background technique [0002] In the 3GPP (3rd Generation Partnership Project, third generation mobile communication partnership project) WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) R7 version, in order to improve UE (User Equipment, user equipment) in Cell_FACH (Cell_ForwardAccess Channel , Cell Forward Access Channel) and the downlink data reception rate in the Cell_PCH (Paging Channel, paging channel) state, introducing the new feature of enhancing Cell_FACH. Through this feature, the UE can receive downlink data from the HS-DSCH (High Speed ​​Downlink Shared Channel, High Speed ​​Downlink Shared Channel) channel in the Cell_FACH and Cell_PCH states. [0003] In the ongoing 3GPP WCDMA R8 version, for UEs in Cell_FACH state and ...
