Abstract: Wireless communications systems and methods related to providing frequency diversity for communications in an unlicensed spectrum are provided. A first wireless communication device communicates, with a second wireless communication device, an opportunistic frequency-switching configuration for a first frequency band and a second frequency band. The first frequency band and the second frequency band are shared by a first network operating entity and a second network operating entity. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device switches from the first frequency band to a second frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device communicates, with the second wireless communication device after the switching, a second communication signal in the second frequency band based on the opportunistic frequency-switching configuration.

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: Techniques are described for wireless communication. A first method includes transmitting a first signal to indicate accessing a first channel in a radio frequency spectrum band, and transmitting information with the first signal in the radio frequency spectrum band. A second method includes winning contention to access a radio frequency spectrum band, and after the winning contention to access the radio frequency spectrum band, transmitting a first signal to align a starting point of a second signal with a reference boundary associated with the radio frequency spectrum band. A third method includes winning contention to access a radio frequency spectrum band during a first frame period, the first frame selected from a plurality of different frame periods, and transmitting a signal at a periodicity during one or more subframes of the first frame period for each of the plurality of different frame periods.

Abstract: A base station may configure a set of autonomous uplink (AUL) resources for a specific base station receive beam, or the AUL resources may be configured for specific user equipment (UEs) or user groups. Additionally, the AUL resources may be configured to include a sensing portion, a data portion, or both. As an example, a UE may receive an AUL configuration that includes an indication of a set of AUL resources that are specific to a base station receive beam. The UE may then determine that the set of AUL resources is available and perform an AUL transmission of uplink data using the set of beam-specific AUL resources. Additionally or alternatively, the UE may perform the AUL transmission with respective portions that include a sensing signal and the uplink data. The base station may use the sensing signal to determine a receive beam on which to receive the uplink data.

Abstract: Techniques are described for wireless communication. A first method includes winning a contention for access to an unlicensed radio frequency spectrum band, and transmitting at least a portion of a channel usage beacon signal (CUBS) over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted in a number of frequency interlaces of the unlicensed radio frequency spectrum band. A second method includes winning a contention for access to an unlicensed radio frequency spectrum band; determining whether the contention is won within a threshold time before a next symbol period boundary; and transmitting at least a portion of a CUBS over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted during a preamble including a fractional period of a first symbol period. The at least portion of the CUBS may be based at least in part on the determining.

Abstract: Certain aspects relate to methods and apparatus for discovering whether one or more enhanced capabilities are supported by devices (e.g., user equipment (UE), base station (BS), etc.) in a network. The enhanced capabilities may include, for example, the ability to support certain low latency procedures, enhanced component carrier (eCC) capability, and the like. The devices in the network may perform one or more handover-related procedures (e.g., cell selection/reselection, make-before-break handover, etc.) and/or other procedures (e.g., QoS negotiation, etc.) based, at least in part, on support for the one or more enhanced capabilities.

Abstract: Technology neutral coexistence and high priority traffic is disclosed for use in unlicensed frequency bands. Synchronization boundaries are defined in which synchronous contention windows across all radio access technologies attempting access to a shared communication channel occur periodically. Between the synchronous contention windows, the nodes may return to asynchronous access procedures. Such synchronous access procedures may be applicable to certain power classes or deployment type nodes. Additionally, various priority schemes for the synchronous contention window may be used to ensure protection of higher priority nodes or traffic, such as ultra-reliable low latency communication (URLLC) traffic. According to certain aspects, the deployment of such synchronous access methodology may be triggered via signaling from initiating devices. Additional aspects may provide for a technology neutral receiver protection mechanism by defining resources for protection signaling during receiver protection intervals between successive synchronous contention windows.

Abstract: A method, apparatus, and computer-readable medium that enable and disable autonomous downlink transmission (ADT) capability at a user equipment (UE) or a gNB are disclosed. The ADT capability is enabled when a triggering event occurs. The ADT capability is realized in part via initiating a listen before talk (LBT) procedure of a first LBT type to obtain an uplink (UL) transmission opportunity (TxOP) after determining that the UE does not have any UL data to transmit, transmitting uplink control information (UCI) with a limited amount of data to request for a resource grant of the TxOP for pending DL data; and receiving the pending DL data, wherein resources for receiving the pending DL data is dynamically configured via the UCI or semi-statically configured through a radio resource control (RRC) protocol message.

Abstract: The disclosure provides for control plane measurements in a wireless device. The wireless device may measure, across multiple sub-frames received over an unlicensed spectrum, received cell-specific reference signals (CRS) from a cell to obtain CRS measurements. The wireless device may identify one or both of a first subset of the CRS measurements associated with a first subset of the sub-frames including opportunistic transmissions and a second subset of the CRS measurements associated with a second subset of the sub-frames including guaranteed transmissions. The wireless device may compute one or both of a first signal to interference plus noise ratio (SINR) value for the first subset of the CRS measurements and a second SINR value for the second subset of the CRS measurements. The wireless device may monitor a radio link condition of the wireless device based at least in part on the first SINR value or the second SINR value.
