1. A method performed by a user equipment (UE) for logical channel (LCH) configuration in small data transmission (SDT), the method comprising:
receiving, from a base station (BS), a radio resource control (RRC) release message;
determining whether the RRC release message includes a specific configuration, the specific configuration including an SDT configuration and an SDT-specific LCH configuration;
transitioning to an RRC_INACTIVE state after determining that the RRC release message includes the specific configuration;
initiating an SDT procedure based on the SDT configuration when the UE is in the RRC_INACTIVE state; and
applying at least one LCH restriction parameter included in the SDT-specific LCH configuration for performing a Logical Channel Prioritization (LCP) procedure during the SDT procedure, wherein:
the SDT-specific LCH configuration is included in a configured grant (CG)-SDT-specific configuration, and
the CG-SDT-specific configuration is included in the SDT configuration.
