Abstract: A user equipment (UE) may transmit a power headroom report in response to changing beamforming parameters. The UE may autonomously change beamforming parameters from a preconfigured set of beams or receive a command to change beamforming parameters for transmissions on a new beam. The UE may determine a power headroom applicable to a transmission from the UE on the new beam. The UE may transmit, in response to the command, a power headroom report based on the power headroom using resources configured for the power headroom report. For example, the power headroom report may be multiplexed with an uplink transmission from the UE using the new beam. In an aspect, the UE may select a scheduled transmission during a time period after the command is implemented as the uplink transmission. For example, the power headroom report may be transmitted as a physical layer transmission or as a MAC-CE transmission.

Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink grant that does not include a downlink assignment index (DAI); determine a pre-defined bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the pre-defined bundle window. In some aspects, a UE may receive a downlink grant that does not include a DAI; determine a bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI, wherein the bundle window is not pre-defined; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the bundle window. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink power control. Certain aspects provide a method for performing uplink power control at a base station (BS). The method includes determining a first configuration of one or more parameters for uplink power control at a user equipment (UE) based on a first spatial beam selected, from a plurality of spatial beams, for uplink communication of the UE. The method further includes transmitting a first indication of the first configuration to the UE.

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: Wireless communications systems and methods related to autonomous uplink transmission in a shared spectrum are provided. A first wireless communication device identifies a transmission opportunity (TXOP) in a shared spectrum shared by the plurality of network operating entities. The first wireless communication device is associated with a first network operating entity of the plurality of network operating entities. The first wireless communication device identifies a resource in the TXOP designated for autonomous communication. The first wireless communication device communicates autonomous data with a second wireless communication device associated with the first network operating entity during the TXOP using the resource.

Abstract: Techniques for reporting channel state information (CSI) for multiple cells (e.g., carriers) using multiple control channel formats are disclosed. A user equipment (UE) may be configured for operation on a plurality of cells. The UE may be configured to periodically report CSI for the plurality of cells and may also report CSI whenever requested. The UE may be configured with a plurality of control channel formats for sending CSI and possibly other control information in different subframes. The plurality of control channel formats may be associated with at least two different capacities. The UE may report CSI for the plurality of cells in the plurality of subframes based on the plurality of control channel formats.

Abstract: The present disclosure provides an example method and an apparatus for transmitting synchronization signals from an eNB with a different subcarrier spacing from rest of transmissions. That is, a primary synchronization signal (PSS), a secondary synchronization signal (SSS) may be transmitted using a first subcarrier spacing, a physical broadcast channel (PBCH), and/or a reference signal (RS) may be transmitted with a second subcarrier spacing, and other transmissions may be made using a third subcarrier spacing that is different from at least one of the first or second subcarrier spacing. Further, the order of symbols mapped to the synchronization signals may be reversed or otherwise modified within a transmission subframe.

Abstract: Methods and apparatuses for wireless communications are described. The aspects relate to a frame structure for new radio shared spectrum. For instance, the frame structure may provide shared medium access by multiple operators in a new radio shared spectrum system. Specifically, the present aspects provide for utilizing reservation preambles associated with a distinct operator for announcing to other operators a reservation of at least one transmission opportunity of a given frame in the new radio shared spectrum.
