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: In an example, a User Equipment (UE) is configured with one or more first Physical Uplink Control Channel (PUCCH) resources on a primary cell (PCell) and configured with one or more second PUCCH resources on a secondary cell (SCell). The PCell and the SCell are associated with a PUCCH group. Before a first slot, the UE changes an active uplink (UL) bandwidth part (BWP) of a cell. The cell associated with the changing the active UL BWP is the PCell or the SCell. A first occasion of the PCell is before the changing the active UL BWP. A second occasion of the SCell is before the changing the active UL BWP. The first occasion and the second occasion are associated with the first slot. The UE determines whether or not to include Hybrid Automatic Repeat request (HARQ) information, associated with the second occasion, in a HARQ codebook based on whether or not the SCell, associated with transmitting the HARQ codebook, is the same as the cell associated with the changing the active UL BWP. The UE transmits, in the first slot and on the SCell, a PUCCH including the HARQ codebook.

Abstract: A method and apparatus such as a device to perform sidelink communication including receiving a sidelink grant from a network node, wherein the sidelink grant schedules or assigns multiple sidelink resources, generating a data packet comprising or multiplexing sidelink data from Sidelink (SL) logical channel(s) with SL Hybrid Automatic Request (HARQ) feedback enabled, 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, and the device being allowed to drop, skip, or cancel a sidelink transmission on one sidelink resource of the two adjacent, neighbor, or consecutive sidelink resources among the multiple sidelink resources if the time gap of the two adjacent, neighbor, or consecutive sidelink resources is less than a minimum time gap.

Abstract: In an example, a User Equipment (UE) operates with shared spectrum channel access on a carrier and/or a cell. The UE receives a configuration for configuring configured grants for uplink transmission in a bandwidth part (BWP). The configured grants include a first configured grant and a second configured grant. The UE configures a first minimum Downlink Feedback Indication (DFI) time delay for the first configured grant according to the configuration. The first minimum DFI time delay is for validation of Hybrid Automatic Repeat Request (HARQ) information in response to one or more first uplink transmissions. The UE configures a second minimum DFI time delay for the second configured grant according to the configuration. The second minimum DFI time delay is for validation of HARQ information in response to one or more second uplink transmissions. The UE does not expect the second minimum DFI time delay to have a different value than the first minimum DFI time delay.
