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: 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.
