Abstract: A method and apparatus are disclosed. The first UE establishes a first sidelink Signaling Radio Bearer (SRB) for PC5-S message transmission if a unicast link or a PC5-Radio Resource Control (PC5-RRC) connection establishment is initiated, wherein the first sidelink SRB is associated with a default Destination Layer-2 Identity (ID). Also, the first UE transmits a first PC5-S message for the unicast link or the PC5-RRC connection establishment on the first sidelink SRB with a Source Layer-2 ID derived from a Layer-2 ID of the first UE and a Destination Layer-2 ID derived from the default Destination Layer-2 ID. Furthermore, the first UE receives a second PC5-S message from a second UE, wherein the second PC5-S message is transmitted with a Source Layer-2 ID derived from a Layer-2 ID of the second UE and a Destination Layer-2 ID derived from the Layer-2 ID of the first UE. In addition, the first UE establishes a second sidelink SRB for PC5-S message reception and/or transmission, wherein the second sidelink SRB is associated with the Layer-2 ID of the second UE. Furthermore, the first UE establishes a third sidelink SRB for PC5-RRC message transmission if the unicast link or the PC5-RRC connection establishment has been successfully completed, wherein the third sidelink SRB is associated with the Layer-2 ID of the second UE.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), if sidelink packet duplication is configured or enabled for a Sidelink Radio Bearer (SLRB), a first Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), corresponding to a first PDCP Service Data Unit (SDU), and a duplicate of the first PDCP PDU, are transmitted. A first PDCP Sequence Number (SN) of the first PDCP PDU is set based upon one or more state variables used for sidelink transmission on the SLRB. If the sidelink packet duplication is de-configured or disabled for the SLRB, a second PDCP PDU, corresponding to a second PDCP SDU, is transmitted. Noduplicate of the second PDCP PDU is transmitted. A second PDCP SN of the second PDCP PDU is set based upon the one or more state variables used for sidelink transmission on the SLRB.

Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment) for applying header compression and decompression on a Sidelink Radio Bearer (SLRB). In one embodiment, the method includes the UE obtaining at least one Packet Data Convergence Protocol (PDCP) parameter for the SLRB from a network node. The method also includes determining whether the header compression and decompression is used for transmitting (Vehicle-to-Everything) V2X messages on the SLRB according to whether (Internet Protocol) IP based or non-IP based V2X messages are to be transmitted on the SLRB, wherein the header compression and decompression is used if IP based V2X messages are to be transmitted on the SLRB, and the header compression and decompression is not used if non-IP based V2X messages are to be transmitted on the SLRB.

Abstract: A method and apparatus are disclosed from the perspective of a first UE (User Equipment) to indicate a network node for releasing SLRB (Sidelink Radio Bearer) or SL-DRB (Sidelink-Data Radio Bearer). In one embodiment, the method includes transmitting a first RRC (Radio Resource Control) message to a network node for requesting sidelink resource, wherein the first RRC message includes a PFI (PC5 QoS Flow Identifier) of a PC5 QoS (Quality of Service) flow in a first list of PC5 QoS flows. The method also includes receiving a second RRC message from the network node, wherein the second RRC message configures a SLRB and maps the PC5 QoS flow to the SLRB. The method further includes transmitting a third RRC message to the network node if the PC5 QoS flow is deactivated or released, wherein the PFI of the PC5 QoS flow is removed from a second list of PC5 QoS flows included in the third RRC message.

Abstract: Methods and apparatuses for improving initialization of sidelink duplication reception in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) receives a first Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU) on a logical channel associated with a sidelink radio bearer (SLRB). The UE initializes a first state variable based on a partial Reordering_Window and a PDCP Sequence Number (SN) of the first received PDCP PDU, wherein the first state variable indicates the PDCP SN of a last PDCP Service Data Unit (SDU) delivered to the upper layers by a PDCP entity created for the SLRB, and the partial Reordering_Window is less than a Reordering_Window. The UE performs a re-ordering procedure for the first PDCP PDU using the initialized first state variable.
