Embodiment approach

[0070] In the third embodiment, whether the uplink is carried in the PDCCH in the downlink resources at the non-start position of the DRX cycle

[0073] Optionally, whether to report the CQI is carried in the downlink physical control channel PDCCH sent to the UE using the downlink resources

[0074] In the PDCCH in the downlink resources before the DRX cycle, the indication information of whether to report the CQI is carried; or

[0075] The PDCCH in the downlink resources at the start position of the DRX cycle carries an indication of whether to report the CQI

[0076] The PDCCH in the downlink resources at the non-starting position of the DRX cycle carries an indication that the CQI is not to be reported

[0078] In the CQI reporting and the indicating method provided by the embodiment of the present invention, through PDCCH detection, in the current DRX Cycle

[0079] Based on the same inventive concept, the embodiments of the present invention also provide a CQI report and an ...

Abstract

The invention discloses a CQI reporting and indicating method, device and storage medium, which are used for reporting the CQI of the current DRX cycle in real time for the current DRX cycle and improving the utilization efficiency of wireless resources. The CQI reporting method includes: for any DRX cycle, receiving the PDCCH in the downlink resource sent by the network side, the PDCCH carrying There is indication information of whether to report channel quality indication CQI; detecting PDCCH in downlink resources; according to the indication information, determining whether to report CQI before PDSCH in On Duration of the DRX cycle.

Description

A kind of CQI report and its indication method, device and storage medium technical field The present invention relates to the technical field of wireless communication, in particular to a kind of CQI reporting and indicating method, device and storage thereof medium. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. here The description is not admitted to be prior art by inclusion in this section. [0003] CQI (Channel Quality Indicator, Channel Quality Indicator) is a measurement of the communication quality of a wireless channel standard. Use 0 to 15 to represent the channel quality of the PDSCH. 0 means the worst channel quality, 15 means the best channel quality. CQI is Using the recommended RI (rank indication, rank indication) and PMI (Precoding Matrix Indicator, precoding matrix indication), and PDSCH (Physical Downlink Shared Channel, Physical Dow...
