Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE) configured with bundled transmission, the UE initializes a configured uplink grant. The UE performs a plurality of transmissions within a bundle of a Medium Access Control Protocol Data Unit (MAC PDU) using the configured uplink grant. The UE stops a Discontinuous Reception (DRX) timer in response to a first transmission of the plurality of transmissions, wherein the DRX timer is not stopped in response to one or more second transmissions of the plurality of transmissions. When the DRX timer is running, the UE monitors a downlink control channel for an uplink grant for retransmission.

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.
