Embodiment Construction

[0034] In the embodiment of the present invention, only the target UE is configured to report the aperiodic CQI report, and the time period for triggering the target UE to report the aperiodic CQI report is configured. That is to say, the aperiodic CQI reporting of the target UE is made periodic to obtain better frequency selective scheduling results, so as to fully exploit the advantages of frequency selective scheduling and improve the performance gain of system performance. At the same time, since aperiodic CQI reporting is only configured for target UEs, instead of configuring all UEs to use aperiodic CQI reporting, resource overhead caused by aperiodic CQI reporting can be reduced.

[0035] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] An embodiment of the present invention provides a method for configuring a CQI reporting mode, and its implementation i...

Abstract

The invention discloses a method and device for configuring a channel quality indication reporting mode. The method comprises the steps that whether user equipment is target user equipment or not is judged; if yes, the operation that an aperiodic channel quality indication report is reported by the user equipment is configured, and a time cycle that the user equipment is triggered to report the aperiodic channel quality indication report is configured; if not, the operation that the user equipment reports a periodical channel quality indication report is configured. According to the method and device for configuring the channel quality indication reporting mode, periodization of aperiodic channel quality indication reporting of the target user equipment is realized, as a result, a better frequency selectivity dispatching result can be obtained, the advantages of frequency selectivity dispatching can be fully explored, and performance gain of system performance is improved. Meanwhile, the aperiodic channel quality indication report is configured for only the target user equipment instead of all user equipment, and therefore the resource expenditure caused by aperiodic channel quality indication reporting can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for configuring channel quality indication reporting modes. Background technique [0002] Frequency selective scheduling means that the base station side scheduler selects the optimal physical resource block (PRB) within the entire system bandwidth according to the subband channel quality indicator (CQI, Channel Quality Indicator) reported by the user equipment (UE, User Equipment). , Physical Resource Block) resources are allocated to users. The base station can obtain the subband CQI by configuring the UE to report the periodic CQI and / or the aperiodic CQI. [0003] The Media Access Control (MAC, Media Access Control) layer at the base station side instructs the UE to report the aperiodic CQI by sending the PDCCH. The aperiodic CQI reporting is a request-response mode, and one request on the base station side corresponds to one aperiodic C...
