Abstract: Methods and apparatus are provided for shortened Transmission Time Interval (sTTI) configurations for low latency communications. A User Equipment (UE) receives at least one transmission in a first TTI of a first duration configured for the UE, the first TTI assigned within a second TTI of a second duration, wherein the first TTI is configured for Ultra-Reliable and Low-Latency Communications (URLLC) and uses, at least in part, a configuration for communicating using the second TTI.

Abstract: The present methods and apparatus enable transmission of an interlaced reference signal for two UEs using a comb structure. In some aspects, the present methods and apparatus may allocate resources and indicate whether a first UE and a second UE are to transmit DM-RS with a comb structure in a single slot based on the allocation. Further, in some aspects, the present methods and apparatus may allocate resources and transmit information indicating whether a first UE is to transmit DM-RS in a first slot or in both a first slot and a second slot within a subframe.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to synchronization for standalone long term evolution (LTE) broadcast. In one aspect, a method is provided which may be performed by a wireless device such as a base station (BS). The method generally includes providing unicast coverage to one or more user equipments (UEs) in a unicast coverage area within a larger coverage area, transmitting unicast data in one or more subframes, and transmitting synchronization signals within one or more of the broadcast subframes, wherein the broadcast signals are transmitted as single frequency network (SFN) transmissions synchronized with transmissions from one or more other base stations providing unicast coverage within the larger coverage area.

Abstract: Certain aspects of the present disclosure provide techniques that may be used for low latency communications. For example, aspects allow a single group acknowledgement to be used to acknowledge a plurality of low latency transmissions. An exemplary method generally includes receiving, from a base station, a plurality of downlink channel transmissions, wherein each of the downlink channel transmissions is sent using a first transmission time interval (TTI) that is reduced relative to a legacy TTI and providing, in a single uplink channel transmission sent using a second TTI that is larger than the first TTI, a group acknowledgement indicating whether or not the downlink channel transmissions were successfully received by a UE.

Abstract: Various aspects described herein are related to communicating feedback communications received over multiple component carriers (CCs) in wireless communications. The communications can be received from a serving node over the multiple CCs configured in carrier aggregation or multiple connectivity. One or more of the multiple CCs can be determined for transmitting feedback regarding the communications received over at least one CC of the multiple CCs, wherein the one or more of the multiple CCs are selected for transmitting the feedback based at least in part on a transmission time interval (TTI) duration for the at least one CC. Feedback related to receiving the communications from the serving node over the at least one CC can be transmitted over the one or more of the multiple CCs.

Abstract: Various aspects described herein relate to communicating using a configurable bandwidth. A user equipment (UE) can receive a control channel from a serving evolved Node B (eNB), where the control channel includes a resource grant for an uplink shared data channel including a number of resource block groups starting from a starting resource block group in an allocation space, and where the allocation space includes a plurality of resource block groups in a frequency domain over a plurality of symbols in a time domain. The UE can transmit data in the uplink shared data channel starting from the starting resource block group in the allocation space and continuing through the number of resource block groups in the allocation space over the frequency domain first and over the time domain second.
