    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.

    Abstract: In an example, a UE receives, from a network, a configuration of a sidelink resource pool. Physical Sidelink Feedback Channel (PSFCH) resources of the sidelink resource pool are configured, periodically with a period of N slots, in slots of the sidelink resource pool. The UE receives, from the network, a configuration with a set of time offsets for determining an association set. The UE determines one or more slots. Each slot of the one or more slots is in the association set and contains a PSFCH resource of the sidelink resource pool. The UE generates a sidelink Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook based upon one or more occasions associated with one or more PSFCH resources of the sidelink resource pool. The one or more occasions is determined or derived based upon the one or more slots and the period of N slots.
