Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

Abstract: Apparatus, methods, and computer-readable media for applying different power control commands for particular transmissions on a same channel are disclosed. An example method of wireless communication at a User Equipment includes determining a first transmission power for a first transmission using first transmission power control parameters, and transmitting the first transmission using the first transmission power. The example method also includes determining a second transmission power for a re-transmission using second transmission power control parameters. The example method further includes transmitting the re-transmission using the second transmission power.

Abstract: A method of wireless communication includes configuring a small cell with activation parameters. The activation parameters include a new carrier type having a reduced periodicity. The method also includes configuring a UE with time restricted measurements. The time restricted measurements correspond to the new carrier type and the reduced periodicity. The method further includes receiving small cell signal measurements from the UE and initiating an activation sequence in response to the small cell signal measurements.

Abstract: The disclosure provides a method and system for requesting access to resources for uplink communications in unlicensed spectrum. In particular, a user equipment (UE) may detect one or more of a first type of data or a second type of data to be transmitted to a base station (BS). The UE may then determine if a first type of physical random access channel (PRACH) resource is available for transmitting one or more of the first type of data or the second type of data to the BS. If the first type of PRACH resource is available, then the UE may transmit one or more of the first type of data or the second type of data using the first type of PRACH resource. If the first type of PRACH resource is not available, then the UE may transmit the second type of data using a second type of PRACH resource.

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 communication systems and methods related to spectrum use negotiations are provided. A first wireless communication device transmits, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum for a time period. The first wireless communication device receives, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from a first priority to a second priority for accessing the spectrum during the time period. The first wireless communication device communicates with a second wireless communication device in the spectrum during the time period based on the second priority, where at least the first wireless communication device or the second wireless communication device is associated with the local operator.

Abstract: Methods and apparatus for supporting adaptive resource negotiation between evolved node Bs (eNBs) for enhanced inter-cell interference coordination (eICIC) are provided. This resource negotiation may occur via a network backhaul between the eNBs or, in some cases, using over-the-air messages (OAMs). For certain aspects, a first eNB may propose its adaptive resource partitioning information (ARPI) to a second eNB, where the second eNB may accept or reject the proposed resource partitioning. If the second eNB accepts the proposed partitioning, the second eNB may schedule resources, such as subframes, based on the accepted partitioning.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A base station transmits a provisional grant uplink assignment to a set of UEs. When a UE receives the provisional grant uplink assignment, the UE performs a clear channel assessment (CCA) operation on a secondary component carrier (SCC) based on the provisional grant UL assignment, the SCC being a contention-based carrier. Then, the UE transmits a schedule request (SR) on the SCC when the CCA operation succeeds. The base station transmits grant confirmation(s) on the SCC in response to the detected SR(s). Once the UE receives a grant confirmation on the SCC in response to the SR, the UE transmits data on the SCC.

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.
