Problems solved by technology

The existing 5G NR protocol assumes that the user equipment can only monitor one PDCCH related to the QCL-TypeD attribute; when the terminal supports monitoring multiple PDCCHs related to different QCL-TypeD attributes, there is no existing solution to support it

Abstract

The embodiment of the invention provides a PDCCH monitoring method and device, user equipment and a storage medium. The method comprises the following steps: enabling at least two search spaces to exist at the PDCCH monitoring moments of UE, wherein at least two search spaces are associated with at least two CORESETs, and if the UE is not configured with a CORESET index pool, or the UE is configured with a first CORESET set with a CORESET index pool value of 0 and a second CORESET set with a CORESET index pool value of 1; and enabling the UE to monitor the PDCCH in the first type of CORESET and the second type of CORESET, wherein the quasi co-location type D attributes of the first type of CORESET and the second type of CORESET are different. According to the embodiment of the invention, the PDCCH needing to be received can be monitored in the CORESETs of at least two different quasi-co-location type D attributes associated with at least two search spaces.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a PDCCH monitoring method, device, user equipment and storage medium. Background technique [0002] In the existing 5G new wireless (the 5 th In the generation new radio (5G NR) protocol, at a certain physical downlink control channel (physical downlink control channel, PDCCH) monitoring time, if multiple associated control resource sets (CORESET) have different quasi-co-location types D (Quasi co-location type D, QCL-Type D) property (property), the user equipment monitors the PDCCH according to a certain priority criterion. The existing 5G NR protocol assumes that the user equipment can only monitor one PDCCH related to the QCL-TypeD attribute; when the terminal supports monitoring multiple PDCCHs related to different QCL-TypeD attributes, there is no existing solution to support it. Contents of the invention [0003] The embodiments of the present app...
