FIELD: mobile communication.
SUBSTANCE: terminal determines based on downlink control information (DCI) transmitted by n sets of physical downlink control channel (PDCCH) candidates a virtual resource block corresponding to a physical downlink shared channel (PDSCH) indicated by the DCI. Position of a physical resource block (PRB) of the PDSCH is determined based on a virtual resource block and a PRB position of a target control resource set (CORESET). Target CORESET is one of m CORESETs, the m CORESETs comprising CORESETs associated with sets of SS search spaces corresponding to n PDCCH candidate sets, where n is an integer greater than 1 and m is an integer greater than 1.
EFFECT: determining the position of a physical resource block according to CORESET when there is multiple CORESET, and high accuracy of determining the physical resource block.
