    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 receiving a first MAC-CE (Medium Access Control-Control Element) including or indicating a plurality of TCI (Transmission Configuration Indication) state IDs (Identities) to be activated for receiving PDSCH (Physical Downlink Shared Channel), wherein format of the first MAC-CE depends on amount of the plurality of TCI state IDs. The method further includes the UE activating a plurality of TCI states associated with the plurality of TCI state IDs included or indicated in the first MAC-CE for receiving the PDSCH in response to reception of the first MAC-CE.

    Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE is configured with a first serving cell, and is indicated to activate the first serving cell and an active UL BWP, wherein the first serving cell or the active UL BWP is not configured with Physical Uplink Control Channel (PUCCH) resource(s). The method further includes the UE does not expect to be indicated to transmit a first Physical Uplink Shared Channel (PUSCH) in the first serving cell or the active UL BWP in Radio Resource Control (RRC) connected mode, wherein the first PUSCH is scheduled by a Downlink Control Information (DCI) format without spatial relation field.

    Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE being served and/or configured with a first cell and a second cell. The method also includes the UE transmitting a beam failure recovery request via a PRACH (Physical Random Access Channel) in the second cell in response to the UE detecting that all links associated with monitored control resource set(s) in the second cell have failed. Furthermore, the method includes the UE transmitting a first report via a PUCCH (Physical Uplink Control Channel) in the second cell in response to the UE detecting that all links associated with monitored control resource set(s) in the first cell have failed.
