Abstract: Methods and apparatuses for handling discontinuous reception and partial sensing for sidelink communication to reduce potential latency due to additional sensing, and to improve resource utilization efficiency. A first device can perform sidelink communication to at least a second device, or a second device in a sidelink resource pool, and trigger to perform resource selection for a sidelink data at a timing. The first device can perform sensing for a first contiguous sensing duration before a sidelink on-duration active time of the second device, determine or select a first sidelink resource from a set of sidelink resources, derive or determine the set of sidelink resources based on at least a sensing result in the first contiguous sensing duration, and perform a first sidelink transmission on the first sidelink resource for transmitting the sidelink data to the second device.

Abstract: Control structures and techniques for transmission time interval (TTI) shortening in wireless communication systems are provided. Exemplary techniques can comprise establishing a UE device connection to a base station having a first TTI, wherein the UE device is configured to employ TTI shortening and has a second TTI different from the first TTI and monitoring a first short physical downlink control channel (PDCCH) region for a scheduled downlink (DL) transmission via the second TTI, wherein a time distribution associated with multiple second TTIs within the first TTI is determined based on a control format indicator (CFI) value indicated via the first TTI. Exemplary techniques can further comprise receiving a DL transmission via the second TTI and transmitting a hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) feedback on an associated UL channel for HARQ-ACK feedback, wherein for a number of DL transmissions via the second TTI within one of the first TTI on the associated DL, a number of associated UL channels for HARQ-ACK feedback occur within the same one of the first TTI on the associated UL. Further control structures and techniques for TTI shortening for wireless communication systems are described.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a first User Equipment (UE), the first UE generates a message requesting inter-UE coordination information, wherein the message includes information associated with a first priority value. The first UE generates a Medium Access Control (MAC) Protocol Data Unit (PDU) including the message. The first UE sets a value of a priority field in a first sidelink control information (SCI) based on a second priority value of the message, wherein the second priority value of the message is a configured value and/or a lowest priority value among a defined set of priority values. The first UE transmits the first SCI to one or more UEs including a second UE, wherein the first SCI schedules a first Physical Sidelink Shared Channel (PSSCH) transmission for transmitting the MAC PDU.

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.
