    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 device, the first device determines a second sidelink resource in a first sidelink slot in a carrier and/or a cell, wherein the first device has a configuration of a first sidelink resource pool in the carrier and/or the cell. The first device performs a procedure to select a first sidelink resource in the first sidelink resource pool, wherein the first sidelink resource is selected from among candidate sidelink resources, of the first sidelink resource pool, that are not in the first sidelink slot. The first device performs a first sidelink transmission on the first sidelink resource.

    Abstract: A method and apparatus are disclosed from the perspective of an User Equipment (UE). In one embodiment, the method includes the UE deriving a first pathloss value from a first pathloss reference of a serving cell, wherein the first pathloss value is used for deriving a power headroom value included in a first power headroom report. The method also includes the UE deriving a second pathloss value from a second pathloss reference of the serving cell after deriving the first pathloss value, wherein the second pathloss reference is used for power control for a first Physical Uplink Shared Channel (PUSCH) transmission on the serving cell. The method further includes the UE deriving the pathloss change based on the first pathloss value and the second pathloss value. In addition, the method includes the UE determining whether a second power headroom report is triggered based on whether the pathloss change is more than a threshold.

    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: A method and apparatus are disclosed for latency reduction of device-to-device message in a wireless communication system. In one embodiment, the method includes the UE receiving a grant on a first interface wherein the grant indicates resource for transmitting scheduling information and resources for data transmission on a second interface. The method also includes the UE transmitting a first scheduling information on the second interface in a first specific timing interval and transmits a second scheduling information on the second interface in a second specific timing interval, wherein the timing difference between the second specific timing and the first specific timing is indicated by the grant, and wherein the first scheduling information indicates a first timing offset between the first scheduling information transmission and the data transmission, and the second scheduling information indicates a second timing offset between the second scheduling information transmission and the data transmission, and the first timing offset is different from the second timing offset.
