    摘要: A method and device are disclosed for a User Equipment, UE, to sidelink discontinuous reception, DRX, for sidelink groupcast communication associated with a group. In one embodiment, the method includes the UE assuming or considering a sidelink DRX configuration applied for the sidelink groupcast communication associated with the group, wherein the sidelink DRX configuration comprises at least one of an on-duration timer length used for determining an on-duration at the beginning of each sidelink DRX cycle and/or a cycle length used for determining a length of each sidelink DRX cycle (2805). The method also includes the UE deriving or determining a time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle based on at least an identifier associated with the group (2810). The method further includes the UE transmitting a sidelink control information associated with the group on a sidelink control channel in a period, wherein the period is determined based on the SL DRX configuration and the time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle (2815).

    摘要: Methods and a device are disclosed from the perspective of a second User Equipment (300), UE, to establish one-to-one connection between a first UE and the second UE. In one embodiment, the method includes the second UE initiating 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 (2905). The method also includes the second UE transmitting 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 Quality of Service, QoS, information for the unicast communication or the UE-to-UE communication (2910). The method further includes the second UE transmitting a second PC5-S message to the first UE for completing the second procedure of establishing the one-to-one connection with the first UE for the UE-to-Network communication if the second procedure is initiated, wherein the second PC5-S message does not include any QoS information for the UE-to-Network communication (2915).

    摘要: 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 (1205). 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 (1210).
