Abstract: A method and apparatus are disclosed. In an example from the perspective of a first device, the first device is configured with a second set of slot offsets by a network. The first device receives, from the network, a second Downlink Control Information (DCI) scheduling a sidelink resource. The first device performs sidelink transmission, to a second device, on the sidelink resource. The first device monitors and/or receives a sidelink hybrid automatic repeat request-acknowledgement (SL HARQ-ACK) feedback from the second device in a fourth slot. The SL HARQ-ACK feedback is associated with the sidelink transmission. The first device derives, based on the fourth slot and a second slot offset value indicated by the second DCI, a third slot for transmitting a SL HARQ-ACK to the network. The second set of slot offsets includes the second slot offset value. The SL HARQ-ACK is set/derived/determined based on the received SL HARQ-ACK feedback.

The method further includes the second UE generating a MAC PDU (Protocol Data Unit) comprising the MAC CE and sidelink data from one or more sidelink logical channels, wherein the sidelink data is available for transmitting to the first UE. Furthermore, the method includes the second UE setting a priority field in a first SCI to a fixed or (pre-defined) priority value of the MAC CE. In addition, the method includes the second UE transmitting the first SCI to the first UE, wherein the first SCI schedules a first sidelink transmission for transmitting the MAC PDU.

Abstract: In an example, a second UE receives a first SCI and a second SCI from a first UE in a first slot. A groupcast sidelink transmission is scheduled by the first SCI and the second SCI. The second SCI indicates a location indication, associated with a location of the first UE, and a communication range. A PSFCH resource is determined based upon the first SCI. The second UE doesn't transmit a NACK indication on the PSFCH resource if location information of the second UE is available, the groupcast sidelink transmission isn't successfully decoded, and the second UE is outside the communication range. The second UE transmits the NACK indication on the PSFCH resource if the location information isn't available and the groupcast sidelink transmission isn't successfully decoded, or if the location information is available, the groupcast sidelink transmission isn't successfully decoded, and the second UE is within the communication range.

Abstract: Methods and apparatuses for improving HARQ feedback in shortened TTI in a wireless communication system are disclosed herein. In one method, a user equipment is configured with a processing interval between receiving a downlink data and transmitting a corresponding acknowledgement (ACK)/negative acknowledgement (NACK) response. The UE receives downlink data with 1 millisecond TTI at a downlink subframe. The UE transmits the ACK/NACK response of the downlink data on a resource at an uplink subframe, wherein the resource is based on an offset value if the processing interval is shorter than 4 milliseconds.

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: Methods and apparatuses for QCL association indication for discontinuous transmission indication are disclosed herein. In one method, the UE receives a first configuration of a plurality of reference signals or a configuration of a plurality of reference signal sets in a cell, wherein a reference signal serves as a quasi-co-location reference. The UE receives a second configuration of an association between a pre-emption indication (PI) and one reference signal from the plurality of reference signals or one reference signal set from the plurality of reference signal sets. The UE receives data based on a reference signal from a first reference signal set.

Abstract: In an example, a User Equipment (UE) receives a message associated with Physical Downlink Shared Channel (PDSCH) parameter configuration. The message includes a first parameter indicating a first list of entries associated with time resource allocation for multiple PDSCHs, a second parameter indicating reception of multiple repetitions for a single PDSCH, and a third parameter indicating a second list of entries associated with time resource allocation. Each entry in the second list indicates a single time resource allocation. If the UE receives a Downlink Control Information (DCI) indicative of a first entry in the first list, the UE receives a plurality of PDSCHs based on a plurality of time resource allocations indicated by the first entry. A first repetition number for the plurality of PDSCHs is determined to be one. If the UE receives a DCI indicative of a second entry in the second list, the UE receives one or more PDSCHs with repetition based on a single time resource allocation indicated by the second entry. A second repetition number for the one or more PDSCHs is determined based on the second parameter.
