    Abstract: A method and apparatus are disclosed from the perspective of a transmitting device. In one embodiment, the method includes being configured or allocated with an identity, wherein the identity comprises a first part of the identity and a second part of the identity. The method also includes the transmitting device generating a data packet for sidelink transmission, wherein the data packet includes the second part of the identity. Furthermore, the method includes transmitting device generating a control information associated with the data packet, wherein the control information includes the first part of the identity. The method further includes the transmitting device transmits the control information and the data packet.

    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. In an example, a first device receives first information and second information from a base station. The first device is configured with a configured grant for sidelink communication via the first information. The configured grant is indicative of first resources for sidelink communication. The second information is indicative of one or more timing offsets and an identity for second resources. The first device transmits sidelink data to a second device via a first resource of the first resources. The first device receives and/or detects a first signal, from the second device, indicative of a reception result associated with the sidelink data. The first device determines a second time and a frequency location based on the second information. The first device transmits a second signal to the base station via a second resource associated with the second time and the frequency location.
