    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.

    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.

    Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE performing transmission and/or reception in a serving cell, wherein the serving cell is in unlicensed spectrum. The method further includes the UE being configured to receive slot format indication (SFI) on periodic SFI monitoring occasion(s), wherein periodic SFI monitoring occasion(s) is (pre-)configured by a network. The method also includes the UE, in response to receiving and/or detecting a channel indicator, monitoring and/or detecting a first SFI-related signal on a first occasion, wherein the first occasion is not one of (pre-)configured periodic SFI monitoring occasion(s).

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE being configured with a control resource set (CORESET). The method further includes the UE receiving a Downlink Control Information (DCI) on the CORESET, wherein an index is included in the DCI and the index indicates a time domain resource allocation pattern. The method also includes the UE receiving data in Orthogonal Frequency Division Multiplexing (OFDM) symbols determined according to the time domain resource allocation pattern, wherein a range of the time domain resource allocation pattern starts from the first OFDM symbol of the CORESET or after an offset from the first OFDM symbol of the CORESET, and the range of the time domain resource allocation pattern may end across a slot boundary.

    Abstract: A method and apparatus are disclosed. In an example, a first device receives a configuration and/or an information, wherein the configuration and/or the information is indicative of a DRX pattern, of the second device, associated with monitoring the sidelink resource pool. The first device transmits a signal to at least the second device on a first opportunity of a plurality of opportunities, wherein the signal indicates the second device to perform monitoring and/or sensing for a first duration. The first device selects a first candidate resource in the sidelink resource pool, wherein the first candidate resource is in a sleep time of the DRX pattern of the second device. The first device transmits a first sidelink transmission, including a sidelink data and/or a sidelink traffic, on the first candidate resource to the second device.

    Abstract: A method and apparatus are disclosed from the perspective of a first device. In one embodiment, the method includes the first device receiving a configuration, from a network node, of a first sidelink resource pool without any Physical Sidelink Feedback Channel (PSFCH) resource. The method further includes the first device receiving a first sidelink grant transmitted, configured, or scheduled by the network node, wherein the first sidelink grant schedules or indicates at least a first sidelink resource in the first sidelink resource pool. Furthermore, the method includes the first device expecting or considering that the first sidelink grant provides no Physical Uplink Control Channel (PUCCH) resource for reporting Sidelink (SL) Hybrid Automatic Repeat Request (HARD) feedback.
