1. A method performed by a user equipment (UE), the method comprising:
receiving configuration information related to a dual active protocol stack based handover (DAPS HO) operation; and
performing the DAPS HO operation based on the configuration information,
wherein performing the DAPS HO operation comprises:
performing a transmission of a message A, which includes a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH), on a target cell included in a target master cell group (MCG) for the DAPS HO operation, and
wherein, based on i) the transmission of the message A on the target cell overlapping in time with an uplink transmission on a source cell included in a source MCG for the DAPS HO operation and ii) the source cell and the target cell being within different frequency bands, the method further comprises:
determining a transmission power for the transmission of the message A on target cell and a transmission power for the uplink transmission on the source cell based on preconfigured priorities within a maximum transmit power of the UE, and
wherein the PRACH included in the message A has a higher priority than a priority of the PUSCH included in the message A.
