Abstract: Methods and apparatuses for handling device-to-device feedback transmission in a wireless communication system are disclosed herein. In one method, a first device receives a configuration for operating in a network scheduling mode for acquiring sidelink resources. The first device receives a sidelink control information with a report request from a second device. The first device triggers or is triggered to transmit a report to the second device in response to the report request. If the first device has no available sidelink resource for transmitting the report, the first device triggers a scheduling request. The first device transmits a signaling of the scheduling request to the network. The first device receives a sidelink grant from the network. The first device utilizes sidelink resource(s) indicated by the sidelink grant to transmit the report to the second device.

Abstract: A method and apparatus are disclosed from the perspective of a device to perform sidelink communication. In one embodiment, the method includes the device receiving a sidelink grant from a network node, wherein the sidelink grant schedules or assigns multiple sidelink resources. The method further includes the device generating a data packet comprising or multiplexing sidelink data from Sidelink (SL) logical channel(s) with SL Hybrid Automatic Request (HARD) feedback enabled. The method further includes the device performing two sidelink transmissions for the data packet on two adjacent, neighbor, or consecutive sidelink resources among the multiple sidelink resources if a time gap of the two adjacent, neighbor, or consecutive sidelink resources is larger than or equal to a minimum time gap.

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 from the perspective of a UE, wherein the UE is allocated with multiple SR configurations by a network node. In one embodiment, the method includes the UE triggering a MAC control element if a timer expires. The method also includes the UE triggering a SR for the MAC control element. The method also includes the UE transmitting the SR based on a first SR configuration of the multiple SR configurations, wherein the first SR configuration is associated with a highest priority logical channel having data available for transmission when the MAC control element is triggered.
