    Abstract: Methods and apparatuses are provided for ensuring, for a unified TCI framework, a MAC CE format for associating code-point of a TCI field, and a TCI state for DL/UL beam indications. A UE can receive a MAC CE for associating at least one TCI state with at least one code-point of a TCI field in a DCI, wherein the MAC CE comprises at least a first octet including a first TCI state ID field associated with a first TCI state and a first field indicating DL or UL for the first TCI state, a second octet including a second TCI state ID field associated with a second TCI state and a second field indicating DL or UL for the second TCI state, and a third octet including a third field for the UE to determine whether the first TCI state and the second TCI state are associated with a same code-point or different code-points of the TCI field.

    Abstract: Methods and apparatuses for providing control resource set configuration in a wireless communication system are disclosed herein. In one method, a network node transmits a signal indicating at least a first duration and a bit map, wherein the first duration is time duration of a control resource set (CORESET) and the bit map indicates first symbol(s) of monitoring occasion(s) of the CORESET within a slot, and wherein a set of bit position indicates value one in the bit map. The network node is not allowed to transmit the signal such that an interval between two bit positions in the set in the bit map is smaller than a second duration.

    Abstract: A method and apparatus are disclosed. In an example, a first user equipment (UE) may be configured with a first number of carriers corresponding to a maximum number of carriers that the first UE is able to use concurrently and/or transmit on concurrently. The first UE may receive a plurality of sidelink transmissions on a plurality of carriers. The first UE may derive a plurality of slots for transmitting Physical Sidelink Feedback Channels (PSFCHs) based upon resources associated with the plurality of sidelink transmissions. Responsive to determining that a number of carriers of a second plurality of carriers associated with derived transmissions of the PSFCHs exceeds the first number of carriers, the first UE may prioritize one or more PSFCHs of the PSFCHs based upon a rule. The plurality of slots for transmitting the PSFCHs may be at least partially overlapped in the time domain.

    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 first User Equipment (UE). In one embodiment, the method includes the first UE being configured or pre-configured with a sidelink resource pool for sidelink transmission. The method also includes the first UE being triggered to select resources for a TB (Transport Block). The method further includes the first UE selecting a first resource for transmission of the TB. In addition, the method includes the first UE selecting a second resource for HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement) based retransmission of the TB, wherein the second resource is later than the first resource, and a time gap between the first resource and the second resource is larger than or equal to a first time duration. Furthermore, the method includes the first UE transmitting a SCI (Sidelink Control Information) and the TB on the first resource in a slot to a second UE, wherein the SCI indicates the first resource and the second resource.

    Abstract: A method and apparatus are disclosed from the perspective of a network. In one embodiment, the method includes the network configuring a UE (User Equipment) with a plurality of DL (Downlink) BWPs (Bandwidth Parts) of a serving cell, wherein the plurality of DL BWPs comprises a first DL BWP with a first SCS (Sub-Carrier Spacing) and a second DL BWP with a second SCS, wherein the second SCS is different from the first SCS. The method further includes the network configuring the UE with a first monitoring occasion for indicating slot format indication (SFI) in the first DL BWP by indicating a first slot offset and a first slot periodicity. The method also includes the network configuring the UE with a second monitoring occasion for indicating slot format indication (SFI) in the second DL BWP by indicating a second slot offset, and a second slot periodicity, wherein the network is not allowed to indicate the second slot offset and the second slot periodicity such that a time period containing a number of consecutive slots associated with a slot format in the combination of slot formats indicated by a SFI index in the second monitoring occasion does not align slot boundary of a slot with the first SCS, and wherein the number is the ratio of the second SCS to the first SCS.
