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 device are disclosed for PC5 Signaling (PC5-S) message reception from the perspective of a UE-to-UE relay. The UE-to-UE relay receives a first PC5-S message on a first sidelink Signal Radio Bearer (SRB) from a first UE, wherein the first PC5-S message is used to establish a first sidelink security between the UE-to-UE relay and the first UE, to update link identifier(s) associated with a first link between the first UE and the UE-to-UE relay, or to modify the first link between the first UE and the UE-to-UE relay. The UE-to-UE relay also delivers the first PC5-S message to an upper layer of the UE-to-UE relay.

Abstract: A method and apparatus are disclosed. A first sidelink Signaling Radio Bearer (SRB) for PC5-S message transmission is established. The first sidelink SRB is associated with a default Destination Layer-2 Identity (ID). A first PC5-S message is transmitted 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. A second PC5-S message is received from a second UE. 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. A second sidelink SRB for PC5-S message reception and/or transmission is established. The second sidelink SRB is associated with the Layer-2 ID of the second UE.

Abstract: A method and device are disclosed for radio bearer configuration to support User Equipment-to-Network (UE-to-Network) relaying from the perspective of a relay UE. In one embodiment, the relay UE establishes a PC5-Radio Resource Control (PC5-RRC) connection with a remote UE. The relay UE also transmits a RRC message to a network node to request a radio bearer configuration to support UE-to-Network relaying. Furthermore, the relay UE receives a RRC Reconfiguration message from the network node, wherein the RRC Reconfiguration message includes a Uu configuration for a Uu Radio Link Control (RLC) bearer associated with a signalling radio bearer (SRB). In addition, the relay UE receives a RRC Reconfiguration Complete message from the remote UE. The relay UE also transmits the RRC Reconfiguration Complete message on the Uu RLC bearer to the network node.

Abstract: A method and apparatus are disclosed from the perspective of a first UE (User Equipment) to support multiple services on a one-to-one sidelink communication link between the first UE and a second UE. In one embodiment, the first UE initiates a first service. The first UE also establishes the one-to-one sidelink communication link for the first service. Furthermore, the first UE negotiates a security configuration with the second UE for encrypting or decrypting data from the first service. In addition, the first UE initiates a second service. The first UE also encrypts or decrypts data from the second service with the security configuration used by the first service.

Abstract: A method and apparatus are disclosed from the perspective of a first User Equipment (UE) to request dedicated sidelink configuration. In one embodiment, the method includes the first UE transmitting a first Radio Resource Control (RRC) message to a network node, wherein the first RRC message includes a sidelink Quality of Service (QoS) information, and wherein a presence of an identity of a sidelink QoS flow in the sidelink QoS information is mandatory and a presence of a QoS profile of the sidelink QoS flow in the sidelink QoS information is optional. The method also includes the first UE receiving a second RRC message from the network node, wherein the second RRC message includes a dedicated sidelink configuration and the identity of the sidelink QoS flow associated with the dedicated sidelink configuration.
