    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 User Equipment (UE) receives a message including a first parameter indicative of a list of entries associated with time resource allocation for multiple PUSCHs. The list does not include a third parameter for configuring a number of repetitions. The UE does not expect the message to include a second parameter that configures and/or indicates an aggregation factor. The UE receives a Downlink Control Information (DCI) indicative of a first entry in the list. The UE performs one or more transmissions on one or more time occasions. A number of time occasions of the one or more time occasions is based on a number of time resource allocations of the first entry.

    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.

    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.
