    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: In an example, a UE receives, from a network, a configuration of a sidelink resource pool. Physical Sidelink Feedback Channel (PSFCH) resources of the sidelink resource pool are configured, periodically with a period of N slots, in slots of the sidelink resource pool. The UE receives, from the network, a configuration with a set of time offsets for determining an association set. The UE determines one or more slots. Each slot of the one or more slots is in the association set and contains a PSFCH resource of the sidelink resource pool. The UE generates a sidelink Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook based upon one or more occasions associated with one or more PSFCH resources of the sidelink resource pool. The one or more occasions is determined or derived based upon the one or more slots and the period of N slots.

    Abstract: A method and apparatus are disclosed from the perspective of a first device for performing sidelink communication. In one embodiment, the first device includes a MAC CE in a MAC PDU, wherein if the MAC PDU comprises the MAC CE without data, SL HARQ feedback is disabled for the MAC PDU. The first device further includes sidelink data associated with a first sidelink logical channel in the MAC PDU, wherein the first sidelink logical channel is configured to enable sidelink HARQ feedback. The first device also sets or indicates enable SL HARQ feedback for the MAC PDU in a SCI, wherein the SCI schedules a sidelink transmission delivering the MAC PDU. Furthermore, the first device transmits the SCI and performs the sidelink transmission to a second device.

    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.
