    Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE being configured with a first DL (Downlink) BWP (Bandwidth Part) and a second DL BWP. The method also includes the UE receiving and/or monitoring a DCI (Downlink Control Information) in a scheduling CORESET (Control Resource Set) in the first DL BWP, and for determining size of the DCI for decoding, the UE determines whether a TCI (Transmission Configuration Indication) field is present in the DCI or not based on a parameter of the scheduling CORESET before the UE decodes the DCI successfully. The method further includes the UE truncates or pads zero-bits to at least one field (other than the TCI field) in the DCI based on configuration of the second DL BWP after the UE decodes successfully the DCI, wherein a BWP indicator field in the DCI indicates the second DL BWP different from the first DL BWP. In addition, the method includes the UE determines whether the TCI field is present in the DCI or not based on the parameter of the scheduling CORESET in the first DL BWP after the UE decodes successfully the DCI, wherein a BWP indicator field in the DCI indicates the second DL BWP different from the first DL BWP.

    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 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).
