On-demand ss/pbch block

A method of a user equipment (UE) in a wireless communication system, the method comprising:

• determining a first set of parameters for a first set of synchronization signals and physical broadcast channel (SS/PBCH) blocks, wherein the first set of parameters includes a first cell identity (ID) and a first frequency location;
• determining a second set of parameters for a second set of SS/PBCH blocks, wherein the second set of parameters includes a second cell ID and a second frequency location and wherein:
• the first set of SS/PBCH blocks is periodic,
• the second set of SS/PBCH blocks is on-demand and indicated to be transmitted by a base station (BS),
• the first cell ID is different from the second cell ID, and
• the first frequency location is different from the second frequency location;
• receiving a first SS/PBCH block from the first set of SS/PBCH blocks;
• and
• receiving a second SS/PBCH block from the second set of SS/PBCH blocks.

A base station (BS) in a wireless communication system, the BS comprising:

• a processor configured to:
• determine a first set of parameters for a first set of synchronization signals and physical broadcast channel (SS/PBCH) blocks, wherein the first set of parameters includes a first cell identity (ID) and a first frequency location;
• and
• determine a second set of parameters for a second set of SS/PBCH blocks, wherein the second set of parameters includes a second cell ID and a second frequency location and wherein:
• the first set of SS/PBCH blocks is periodic,
• the second set of SS/PBCH blocks is on-demand,
• the first cell ID is different from the second cell ID, and
• the first frequency location is different from the second frequency location;
• and
• a transceiver operably coupled to the processor, the transceiver configured to transmit the first and second set of SS/PBCH blocks.
