Uplink transmissions based on synchronization signals and physical broadcast channel block receptions

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

• a transceiver;
• and
• a controller coupled with the transceiver, and configured to
• transmit, to a user equipment (UE), first information configuring a non-cell-defining synchronization signals and physical broadcast channel (SS/PBCH) block (NCD-SSB),
• transmit, to the UE, second information configuring a random access channel which is dedicated for UEs associated with the NCD-SSB, and
• transmit, to the UE, the NCD-SSB based on the first information,
• wherein the NCD-SSB is different from a cell-defining SS/PBCH block (CD-SSB) which is associated with remaining minimum system information (RMSI), and
• wherein a power related value of the NCD-SSB is same as a power related value of the CD-SSB.

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

• receiving, from a base station (BS), first information configuring a non-cell-defining synchronization signals and physical broadcast channel (SS/PBCH) block (NCD-SSB),
• receiving, from the BS, second information configuring a random access channel which is dedicated for UEs associated with the NCD-SSB;
• and
• receiving, from the BS, the NCD-SSB based on the first information,
• wherein the NCD-SSB is different from a cell-defining SS/PBCH block (CD-SSB) which is associated with remaining minimum system information (RMSI), and
• wherein a power related value of the NCD-SSB is same as a power related value of the CD-SSB.
