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 first device to perform sidelink communication. In one embodiment, the first device sends or reports a resource set to a second device, wherein the resource set comprises one or more sidelink resources in one or more slots in a carrier or cell. Furthermore, when the first device performs sidelink resource (re-)selection procedure for selecting a first sidelink resource in the carrier or cell, the first device prevents or precludes from selecting or determining (any) sidelink resources in the one or more slot in the carrier or cell for selecting the first sidelink resource.

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, a User Equipment (UE) is configured with one or more cells including a second cell. The UE is configured to monitor one or more first UE-specific Physical Downlink Control Channels (PDCCHs) on the second cell. The one or more first UE-specific PDCCHs schedule data transmission on a first cell. The UE receives a Downlink Control Information (DCI) indicative of dormancy information associated with the one or more cells. The DCI indicates dormant status of the second cell. In response to the DCI indicating the dormant status of the second cell, the UE switches a scheduling cell of the first cell from the second cell to the first cell, and the UE monitors one or more second UE-specific PDCCHs on the first cell. The one or more second UE-specific PDCCHs schedule data transmission on the first cell.

Abstract: A method and apparatus are disclosed from the perspective of a first device for performing sidelink transmission in a sidelink resource pool. In one embodiment, the first device has a configuration of the sidelink resource pool, wherein the sidelink resource pool is enabled with resource reservation for different Transport Blocks (TBs). The first device also has a configuration of a list of reserved periods. Furthermore, the first device selects or determines a first reserved period from the list of reserved periods, wherein the first selected or determined reserved period is within a first set of reserved periods. In addition, the first device randomly selects a first integer in a first interval, wherein the first interval is based on a scaling factor and a second interval, and the scaling factor is derived based on a largest reserved period in the first set of reserved periods, and wherein the first integer indicates a number of transmission opportunities of different TBs with the first reserved period. The first device further performs sidelink transmission of one TB on one transmission opportunity from the number of transmission opportunities.
