Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a reserved resource allocation, wherein the reserved resource allocation is associated with a reserved resource; receive information identifying another resource allocation, wherein the other resource allocation overlaps with the reserved resource allocation at an overlapped portion; and selectively perform a communication using the overlapped portion for the reserved resource allocation or the other resource allocation based at least in part on at least one of: respective traffic types of the reserved resource allocation and the other resource allocation, or respective priority levels associated with the reserved resource allocation and the other resource allocation. Numerous other aspects are provided.

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: Methods and apparatus related to interference management for a spectrum (e.g., unlicensed band) shared among multiple wireless communication devices (e.g., user equipment or base stations). A first wireless communication device may generate and transmit to a second wireless communication device an indication that facilitates interference management (e.g., interference estimation, suppression, and/or mitigation). For example, an interfering device may indicate its transmission characteristics to an interfered device to facilitate receiver-side interference suppression, or an interfered device may indicate its reception characteristics to an interfering device to facilitate transmitter-side interference mitigation.

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: Certain aspects of the present disclosure provide procedures for managing secondary eNB (SeNB) radio link failure (S-RLF) in dual connectivity scenarios. A user equipment (UE) may establish communication with a Master Evolved Node B (MeNB) and a Secondary eNB (SeNB). The UE may detect a Radio Link Failure (RLF) of a connection with the SeNB and may transmit an indication of the RLF to the MeNB, in response to the detection. The MeNB may take at least one action to manage the RLF, in response to receiving the indication of the RLF, for example, including transmitting a reconfiguration command to the UE. The SeNB may also detect the RLF and transmit an indication of the RLF to the MeNB over a backhaul connection, in response to the detection.

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 relate to communicating using dynamic uplink and downlink transmission time interval (TTI) switching in a wireless network. A notification can be received from a network entity of switching a configurable TTI from downlink communications to uplink communications. The configurable TTI can be one of a plurality of TTIs in a frame structure that allows dynamic switching of configurable TTIs between downlink and uplink communications within a frame. Additionally, uplink communications can be transmitted to the network entity during the configurable TTI based at least in part on the notification.
