Abstract: Various aspects of the present disclosure generally relate to neural network based channel state information (CSI) feedback. In some aspects, a device may obtain a CSI instance for a channel, determine a neural network model including a CSI encoder and a CSI decoder, and train the neural network model based at least in part on encoding the CSI instance into encoded CSI, decoding the encoded CSI into decoded CSI, and computing and minimizing a loss function by comparing the CSI instance and the decoded CSI. The device may obtain one or more encoder weights and one or more decoder weights based at least in part on training the neural network model. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may perform a listen before talk (LBT) procedure on a channel bandwidth using an energy detection (ED) threshold. The ED threshold being associated with a transmission bandwidth that is narrower than the channel bandwidth. The wireless device may also, responsive to a successful LBT procedure, transmit on the transmission bandwidth according to a frequency hopping pattern during a first channel occupancy time (COT). The frequency hopping pattern comprises a first resource allocation and a second resource allocation different from the first resource allocation.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some implementations, a base station (BS) may transmit downlink (DL) data using a sequence of DL hopping frames on a corresponding sequence of unique hopping channels associated with a DL frequency hopping pattern. In some implementations, each user equipment (UE) of one or more UEs may transmit uplink (UL) data using a sequence of UL hopping frames on a corresponding sequence of unique hopping channels associated with a different UL frequency hopping pattern.

Abstract: Various aspects described herein relate to receiving a first communication over a first set of resources based on a first transmission time interval (TTI), receiving a second communication over a second set of resources based on a second TTI, where the second TTI is smaller than the first TTI, and where the second set of resources overlap the first set of resources defining a common set of resources, and determining whether to prioritize decoding of the first communication over the second communication.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). Additionally, certain aspects of the present disclosure provide techniques for managing communications in a wireless communication system, for example, by using enhanced downlink control channels.

Abstract: Scheduling around frame based equipment (FBE) idle periods reduces the flexibility of scheduling and partitioning. This leads to a latency caused by waiting for the next downlink scheduling opportunity and skipping over unused uplink scheduling slots. According to certain aspects, to reduce overhead caused by idle time and ensure full downlink scheduling, a base station (BS) alternates between idle periods and channel occupancy time every fixed frame period with one or more other synchronized BSs, between components carriers of the BS, or both. Thus, a BS can always schedule downlink on a carrier during an idle period scheduled for a different BS and/or a different carrier.

Abstract: The disclosure relates to drone user equipment (UE) indications that may be conveyed to a wireless network. In particular, a UE that has flight capabilities (i.e., capabilities to operate as an unmanned aircraft system) and optional further capabilities to report a current height level may indicate such capabilities to the wireless network. As such, the wireless network may differentiate the drone UE from other UEs that only operate on the ground. Furthermore, the optional current height level may enable the wireless network to differentiate among drone UEs operating at different heights and/or from other UEs that are operating on the ground. The wireless network may further use the information indicating the flight capabilities either alone or in combination with the optional height information to configure power control parameters, manage interference, provide mobility management functions, generate neighbor lists, control beamforming, or implement a radio resource configuration or management procedure.

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.
