In one embodiment, a method performed by a wireless communication node (e.g., a base station) includes determining an indication (e.g., Tx profile or transmission format) of a version of a sidelink transmission format. The method further includes configuring, according to the indication, a sidelink resource and at least one transmission configuration parameter for a sidelink transmission of a wireless communication device (e.g., a UE). In another embodiment, a method performed by a wireless communication device includes transitioning from a first radio resource control (RRC) state during which a first sidelink transmission is initiated, to a second RRC state. The method further includes using a mapping of a PC5 quality of service (QoS) flow to a sidelink radio bearer (SLRB), in a SLRB configuration of the second RRC state, to continue with the first sidelink transmission. In another embodiment, a method performed by a wireless communication device (e.g., a UE) includes receiving a radio resource control (RRC) reconfiguration message including a sidelink radio bearer configuration from a wireless communication node (e.g., a base station).
