Description

This application relates to the field of mobile communications, and more particularly to resource determination methods, apparatus, devices, and storage media. In NR (New Radio) systems, to enable the transmission of the same PDCCH (Physical Downlink Control Channel) across multiple TRPs (Transmission/Receive Points), network devices configure multiple CORESETs (Control Resource Sets), each CORESET has a corresponding TCI (Transmission Configuration Indication) state, and furthermore, SS sets (Search Spaces) are associated with multiple CORESETs. Each set (search space set) can be configured, meaning that multiple SS sets are configured, each associated with a CORESET and the corresponding TCI state. However, since there are multiple CORESETs associated with SS sets corresponding to multiple PDCCH candidates, the urgent problem to be solved is how to determine the location of the PDCCH's physical resource blocks based on the CORESETs.
