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: Uplink transmission in shorted transmission time intervals is provided herein. A method can comprise receiving, by a device comprising a processor, a first downlink control information related to scheduling a first uplink data transmission via a first transmission time interval. The method can also comprise receiving, by the device, a second downlink control information related to scheduling a second uplink data transmission via a second transmission time interval, wherein the second uplink data transmission overlaps at least a symbol with the first uplink data transmission. The method can also transmitting, by the device, the first uplink data transmission or the second uplink data transmission based on prioritization determined based on a first length of the first transmission time interval and a second length of the second transmission time interval.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a base station, the base station transmits a configuration of a bandwidth part to a User Equipment (UE). The base station determines a subset of frequency resources within the bandwidth part. The base station transmits, to the UE, an indication of one or more allocated resources, within the subset of frequency resources, for a transmission. The base station does not enable interleaved mapping for the transmission.

Abstract: Methods and apparatuses are provided for channel access switching in a wireless communication system, with or without Listen-Before-Talk (LBT), and/or with different types of efficiently operated LBT. A device, including a User Equipment (UE) or a base station, can determine whether and/or how to perform LBT for a transmission based on a property of the transmission. The property could be a resource allocation for the transmission. The property could be a way to allocate resources for the transmission. The property could be a length or size of resource allocated for the transmission. The property could be an amount of resources allocated for the transmission. The resource allocation could be a time domain resource allocation and/or a frequency domain resource allocation.
