Method, system and apparatus for uploading feedback information

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 ...

AI Technical Summary

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 the process of receiving the downlink HS-DSCH data, if the wireless environment changes during the process of receiving the downlink HS-DSCH data, the NodeB will not be able to know the current channel characteristics in time, so that it cannot timely Determine the downlink modulation and coding method and transmit power

In addition, compared with CQI, the RACH measurement results are not conducive to the NodeB to more accurately determine the downlink modulation and coding method and transmit power
