Abstract:
A user equipment (UE) is configured to receive a synchronization signal block (SSB) transmission with a first subcarrier spacing (SCS) in an SSB burst window (SSBW), decode the SSB transmission to determine parameters for a control resource set 0 (CORESET #0) to be transmitted in the SSBW using a second SCS that is different from the first SCS, monitor physical downlink control channel (PDCCH) candidates in the determined CORESET #0 based on a mapping between the SSB transmission and the CORESET #0 and decode the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.
