    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.

    Abstract: A method and apparatus are disclosed. In an example, a first device receives first information and second information from a base station. The first device is configured with a configured grant for sidelink communication via the first information. The configured grant is indicative of first resources for sidelink communication. The second information is indicative of one or more timing offsets and an identity for second resources. The first device transmits sidelink data to a second device via a first resource of the first resources. The first device receives and/or detects a first signal, from the second device, indicative of a reception result associated with the sidelink data. The first device determines a second time and a frequency location based on the second information. The first device transmits a second signal to the base station via a second resource associated with the second time and the frequency location.

    Abstract: A method and apparatus are disclosed from the perspective of a first device for performing sidelink transmission to a second device. In one embodiment, the method includes the first device being configured with a first resource pool for sidelink transmission. The method includes the first device being configured with only a first number of consecutive symbols in each slot for sidelink such that each slot in the first resource pool comprises only one subset of consecutive symbols for sidelink and the subset of each slot comprises the same first number of consecutive symbols, wherein the first number of consecutive symbols in each slot for sidelink is less than all OFDM (Orthogonal Frequency Division Multiplexing) symbols in each slot. The method further includes the first device performing resource selection among a plurality of slots in the first resource pool. In addition, the method includes the first device selecting a first resource in a first slot and a second resource in a third slot. Furthermore, the method includes the first device performing sidelink transmission of a TB (Transport Block) on the first resource and performs sidelink transmission of the TB on the second resource.

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment) and/or a base station. In one embodiment, the method includes the base station configuring the UE with a first serving cell and a second serving cell. The method also includes the base station configuring the UE with a periodicity for monitoring a downlink control signal in the first serving cell, wherein the base station is not allowed to configure the UE such that the periodicity includes a non-integer number of symbol(s) of the second serving cell, and wherein the downlink control signal includes a pre-emption indication (PI) for the second serving cell.

    Abstract: A method and apparatus are disclosed. The method includes the UE (User Equipment) being configured with a first CORESET (Control Resource Set). The method also includes the UE being configured with a second CORESET. The method further includes the UE transmitting a preamble for beam failure recovery in response to the UE detecting that beam failure occurs. And the method includes the UE monitoring and/or receiving a DCI scrambled by C-RNTI in the second CORESET in the second slot in response to transmitting the preamble for beam failure recovery. Furthermore, the method includes the UE prioritizing to receive and/or demodulate the DCI scrambled by C-RNTI in the second CORESET in the second slot, if the first number plus the third number exceeds the first maximum number or the second number plus the fourth number exceeds the second maximum number in the second slot.
