The method includes initiating an SDT procedure while the UE is in a Radio Resource Control (RRC) Inactive (RRC_INACTIVE) state; initiating a random access (RA) procedure before the SDT procedure is terminated; and determining whether to include a Cell-Radio Network Temporary Identifier (C-RNTI) Medium Access Control (MAC) Control Element (CE) in an uplink (UL) message during the RA procedure based on at least one condition. The at least one condition includes whether the SDT procedure corresponds to a Configured Grant (CG)-SDT procedure. The UL message is a message 3 (Msg3) in a case that the RA procedure is a 4-step RA procedure. The UL message is a message A (MsgA) in a case that the RA procedure is a 2-step RA procedure.
