Abstract

The present application provides a PDCCH blind detection method, device and storage medium, wherein the method includes: extracting first indication information from MIB data, where the first indication information is used to indicate a time-frequency resource used for performing PDCCH blind detection configuration; according to the time-frequency resource configuration indicated by the first indication information, determine the aggregation degree level order of the PDCCH blind detection; according to the aggregation degree level order, perform PDCCH blind detection on the PDCCH candidate sets that need blind detection under each aggregation degree level, until the detection out DCI. The present application solves the problem of slow UE access to a cell caused by low PDCCH blind detection efficiency in the PDCCH blind detection method in the related art, improves the PDCCH blind detection efficiency, and speeds up the UE access to a cell.

Description

technical field [0001] The present application relates to the field of computers, and in particular, to a PDCCH blind detection method, device and storage medium. Background technique [0002] 5G technology (5th generation mobile technology, fifth-generation mobile communication technology) is a new generation of communication technology. The fifth-generation mobile communication system with mobile Internet and Internet of Things as the main driving force will penetrate into all fields of society and build a comprehensive network for users. A directional information ecosystem to cope with the future explosive growth of mobile data traffic, massive device connections and emerging new services. [0003] At present, for the 5G new air interface, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) defines two networking modes: SA (standalone, independent networking) and NSA (non-standalone, non-independent networking). SA 5G base stations and core netw...
