Abstract: Apparatuses and methods for enhancement to standalone operation for higher frequency range in a wireless communication system. A method includes receiving a synchronization signals and physical broadcast channel (SS/PBCH) block and determining a set of configurations for a control resource set (CORESET #0) to receive a Type0 physical downlink control channel (Type0-PDCCH). The set of configurations includes a multiplexing pattern between the CORESET #0 and the SS/PBCH block; a number NRBCORESET #0 of resource blocks (RBs) for the CORESET #0; a number NsymbolCORESET #0 of symbols for the CORESET #0; and a frequency offset between the CORESET #0 and the SS/PBCH block. For a first multiplexing pattern between the CORESET #0 and the SS/PBCH block, the frequency offset between the CORESET #0 and the SS/PBCH block is determined as one of 0, NRBCORESET #0−NRBSSB, or (NRBCORESET #0−NRBSSB)/2. The method further includes receiving the Type0-PDCCH based on the set of configurations for the CORESET #0 over a downlink channel.

Abstract: A UE in a wireless communication system is provided. The UE comprises a transceiver configured to receive SS/PBCH block over downlink channels using a set of parameters based on an operation mode. The operation mode is configured for the SS/PBCH block as a first operation mode in which the SS/PBCH block is used on a LAA Scell or a second operation mode in which the SS/PBCH block is at least used on a Pcell. The set of parameters is configured as a first set of parameters for the SS/PBCH block when the operation mode of the SS/PBCH block is configured as the first operation mode or a second set of parameters for the SS/PBCH block when the operation mode of the SS/PBCH block is configured as the second operation mode.
