Embodiment Construction

[0045] As described above, in the prior art, the PUSCH resources indicated in the downlink control information are used to report aperiodic CSI. However, the processing time for reporting aperiodic CSI by using PUSCH resources is relatively long, so that the base station cannot obtain CSI quickly, which in turn leads to poor scheduling accuracy of the base station. In addition, the user equipment cannot know the priority of the aperiodic CSI, and cannot report the high-priority aperiodic CSI in time.

[0046] In the embodiment of the present invention, by configuring the priority corresponding to the aperiodic CSI and delivering the priority of the aperiodic CSI to the user equipment, the user equipment can be made aware of the priority of the aperiodic CSI, and then the user equipment can be given priority in the corresponding priority. Aperiodic CSI is reported on the PUCCH resource of the first level. The above solution enables the base station to quickly acquire the aperi...

Abstract

The present invention provides a method for indicating an aperiodic CSI priority, a CSI reporting method and device, and a medium, the method for indicating the aperiodic CSI priority comprising the steps of: configuring a priority corresponding to the aperiodic CSI, the priority corresponding to the aperiodic CSI being suitable for indicating a high priority PUCCH resource or a low priority PUCCH resource corresponding to the aperiodic CSI; and issuing the priority of the non-periodic CSI to the user equipment. According to the scheme, the base station can quickly obtain the aperiodic CSI reported by the PUCCH with the high priority, and then the timeliness and accuracy of base station scheduling are improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a method for indicating aperiodic CSI priority, a CSI reporting method and device, and a medium. Background technique [0002] In a wireless communication system, a base station can send an uplink grant (UL DCI) to a user equipment (UE), and the uplink grant is used to indicate the resources within which the UE can send data to the base station. In UL DCI, the base station can send a channel state information (CSI) trigger, and the UE can initiate an aperiodic CSI (aperiodic CSI, A-CSI) report after receiving the CSI trigger, and the aperiodic CSI report can provide communication between the UE and the base station CSI of the link. [0003] In the new air interface (NR) system, UL DCI triggering aperiodic CSI mainly includes the following steps: [0004] Step 1, high-layer signaling (RRC signaling) configures the aperiodic CSI triggering state table, ...
