    Abstract: A method and device are disclosed for a remote User Equipment (UE) to support UE-to-Network relay communication. The remote UE establishes a PC5 connection with a first relay UE for a relay communication with a first network node. The remote UE also performs a Radio Resource Control (RRC) connection establishment procedure with the first network node via the first relay UE. Furthermore, the remote UE transmits a first RRC message to a second network node via a second relay UE for requesting RRC connection re-establishment, wherein the first RRC message includes a first Cell Radio Network Temporary Identifier (C-RNTI) of the remote UE. Also, the remote UE receives a second RRC message from the second network node via the second relay UE for re-establishing a RRC connection between the second network node and the remote UE, wherein the second RRC message includes a second C-RNTI of the remote UE.

    Abstract: A method and device are disclosed for a remote User Equipment (UE) to receive system information. In one embodiment, the method includes the remote UE receiving a system information from a network node via a relay UE, wherein a sidelink transmission of the system information is sent with a common Layer-2 Identity (ID) as Destination Layer-2 ID and a Layer-2 ID of the relay UE as Source Layer-2 ID, and wherein the common Layer-2 ID is associated with a purpose of delivering or forwarding the system information from the network node.

    Abstract: A method and device are disclosed from the perspective of a second UE. The second UE initiates a first procedure of establishing the one-to-one connection with the first UE for a unicast communication between the first UE and the second UE or for a UE-to-UE communication between the first UE and a third UE via the second UE or a second procedure of establishing the one-to-one connection with the first UE for a UE-to-Network communication between the first UE and a network node via the second UE. The second UE transmits a first PC5-S message to the first UE for completing the first procedure of establishing the one-to-one connection with the first UE for the unicast communication or the UE-to-UE communication if the first procedure is initiated, wherein the first PC5-S message includes QoS information for the unicast communication or the UE-to-UE communication.

    Abstract: A method and apparatus are disclosed from the perspective of a network node. The method includes the network node configuring a UE (User Equipment) with a first DRB (Data Radio Bearer), such that the first DRB is configured with a presence of SDAP (Service Data Adaptation Protocol) header and the network node is not allowed to reconfigure the first DRB for changing the presence of SDAP header to an absence of SDAP header after the first DRB is established. The method further includes the network node configuring the UE to serve a first QoS (Quality of Service) flow and a second QoS flow by the first DRB. The method also includes re-configuring the UE to serve the first QoS flow by a second DRB, which was originally served by the first DRB, when the second QoS flow is released or removed from the first DRB, such that the second DRB is configured with an absence of SDAP header.

    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.
