    Abstract: A method and device are disclosed from the perspective of a remote UE. In one embodiment, the remote UE establishes a Radio Resource Control (RRC) connection with a network node. The remote UE also transmits a Layer 2 Identity (L2ID) of the remote UE to the network node. The remote UE further receives a first RRC Reconfiguration message from the network node for path switching from direct to indirect communication, wherein the first RRC Reconfiguration message indicates a relay UE for the path switching. In addition, the remote UE establishes a PC5 connection with the relay UE. Furthermore, the remote UE transmits a first RRC Reconfiguration Complete message corresponding to the first RRC Reconfiguration message to the network node via the relay UE.

    Abstract: A method and apparatus are disclosed from the perspective of a network node. In one embodiment, the method includes the network node transmitting a first message with a DRB (Data Radio Bearer) configuration to a UE (User Equipment) for establishing a default DRB for a PDU (Packet Data Unit) session, wherein the DRB configuration includes a QFI (QoS Flow Id) configuration used to indicate whether a QFI field is present or not in uplink for the default DRB and the QFI configuration is always set to a value indicating the QFI field is present in uplink for the default DRB. The method further includes the network node establishing the default DRB with a presence of the QFI field in uplink. The method also includes the network node receiving a SDAP (Service Data Adaptation Protocol) PDU with the QFI field via the default DRB from the UE.

    Abstract: A method and device are disclosed for Uu radio bearer to Sidelink (SL) Radio Link Control (RLC) mapping. In one embodiment, the method includes a network node transmitting a Radio Resource Control (RRC) message to a relay User Equipment (UE), wherein the RRC message includes a first information indicating a mapping which represents an association between a Uu radio bearer and a SL RLC bearer and wherein the RRC message also includes a second information identifying a remote UE associated with the mapping. The method further includes the network node transmitting an adaptation layer Protocol Data Unit (PDU) to the relay UE, wherein a header of the adaptation layer PDU includes an identity of the Uu radio bearer and a local UE identifier of the remote UE.

    Abstract: A method and device are disclosed from the perspective of a second User Equipment (UE) to report sidelink capability information. In one embodiment, the method includes the second UE receiving, from a UE-to-UE Relay, a first sidelink UE capability information of a first UE and a second sidelink UE capability information of the UE-to-UE Relay or receives, from the UE-to-UE Relay, a combined sidelink UE capability information, wherein the combined sidelink UE capability information is derived from the first sidelink UE capability information and the second sidelink UE capability information. The method further includes the second UE transmits the first sidelink UE capability information and the second sidelink UE capability information to a network node or transmits the combined sidelink UE capability information to the network node.
