Title:
PHYSICAL DOWNLINK CONTROL CHANNEL TRANSMISSION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/212286
Kind Code:
A1
Abstract:
Disclosed are a physical downlink control channel transmission method and apparatus, and a storage medium, which belong to the technical field of wireless communications. The process of transmitting a physical downlink control channel involves: a base station determining a CORESET configured for a terminal; then numbering resource element groups (REGs) in the CORESET according to a numbering rule corresponding to the CORESET; next, combining the REGs into an REG packet according to an REG mapping rule corresponding to the CORESET, and performing resource mapping on a physical downlink control channel corresponding to the terminal to obtain a control channel element (CCE); and finally, the base station transmitting the physical downlink control channel to the terminal. When resource mapping is performed by means of the REG mapping rule, the capacity of the CORESET can be expanded to obtain a high degree of CCE aggregation, thereby improving the efficiency of the resource mapping.
