Title:
DOWNLINK CONTROL INFORMATION RECEIVING METHOD AND DEVICE, AND DOWNLINK CONTROL INFORMATION SENDING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/164031
Kind Code:
A1
Abstract:
Provided in the present application are a downlink control information receiving method and device, and a downlink control information sending method and device, wherein same relate to the technical field of communications, and are used for realizing a diversity gain of PDCCH transmission. The method comprises: a user equipment receiving indication information of a CORESET, wherein the indication information is used to indicate a first QCL assumption and a second QCL assumption, and the CORESET is associated with a first PDCCH candidate, the first PDCCH candidate comprises a first CCE and a second CCE, both the first CCE and the second CCE comprise one or more CCEs, and serial numbers of the CCEs included in the first CCE and the second CCE are different, the first QCL assumption corresponds to the first CCE, and the second QCL assumption corresponds to the second CCE; and the user equipment respectively receiving downlink control information on the first CCE and the second CCE according to the first QCL assumption and the second QCL assumption.
