CONSTRAINTS ON A SOURCE REFERENCE SIGNAL FOR QUASI-COLLOCATION TIMING REFERENCE OF A POSITIONING REFERENCE SIGNAL
Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.
Fingerprinting enhancement with multi-band AoA measurements
A method and a radio access device for performing the method for positioning of a target station (STA) by a radio access device. The method receives sounding feedback, from a target station (STA), for each of a plurality of subbands in response to sending a sounding signal, the sounding feedback comprising channel quality information for each subband of the plurality of subbands. The method calculates an angle-of-arrival (AoA) characteristic from the sounding feedback for at least a subset of the plurality of subbands and maps the AoA characteristics of the at least the subset of the plurality of subbands to a fingerprint in a fingerprint reference map. The method then determines the location of the target STA based on at least the fingerprint.

DRONE ESCORT SYSTEM
The present disclosure describes systems and methods for escorting small unmanned aircraft (herein drones). An escorting drone approaches the escorted drone and transmits to it an escort signal. In an embodiment, the escort signal is a GNSS signal fashioned to be the same as the GNSS signal that would be received by the escorted drone, other than being slightly stronger in signal strength and having slightly altered component delays. In another embodiment, the escort signal is a radio frequency control channel signal. Escorting may be utilized to guide a drone from a preprogrammed point to a docking zone in a droneport; to guide a drone though an urban canyon or inside a building where GNSS signals are not reliably received; to retrieve a drone with which communications has been lost; or to escort a drone to safety out of a no-flight zone such as around an airport.
METHOD OF WIRELESS GEOLOCATED INFORMATION COMMUNICATION IN SELF-VERIFYING ARRAYS
Methods and apparatus for transmitting information associated with verified positions of Nodes based upon wireless communications between Nodes included in an array. Values for variables derived from multiple wireless transmissions between Nodes are aggregated, and a position of a particular Node may be determined based upon multiple data sets generated by multiple communications between disparate Nodes. Information is geolocated based upon the respective positions of the disparate Nodes. A user interface may provide a pictorial view of positions of all or some Nodes in an array, as well as associated information.
Passive entry/passive start systems and methods for vehicles
Systems and methods for vehicle passive entry/passive start (PEPS) are provided. A communication gateway in a vehicle establishes a Bluetooth low energy (BLE) or an impulse radio ultra-wide band (IR UWB) communication connection with a portable device that includes a wireless charging apparatus. A low-frequency transmitter transmits a ping request to the wireless charging apparatus. The portable device transmits a response to the ping request over the communication connection to the communication gateway. The communication gateway authenticates the portable device based on information included in the received response. A passive entry/passive start (PEPS) system performs a vehicle function in response to the portable device being authenticated, including unlocking a door of the vehicle, unlocking a trunk of the vehicle, allowing a wireless charging station of the vehicle to charge the portable device, or allowing the vehicle to be started.

Autonomous airborne vehicle controlled by millimeter wave radar
Systems and methods are provided for autonomous airborne vehicle control using a millimeter-wave (MMW) radar. Embodiments of the present disclosure enable a MMW radar system to support an unmanned aerial vehicle (UAV) in accomplishing missions involving interacting with peers. In an embodiment, a MMW radar module of a UAV in accordance with an embodiment of the present disclosure enables the UAV to take a measurement (e.g., regarding the location of another UAV) using the MMW radar, classify a return (e.g., a MMW radar return), determine whether the detected object is a peer, and update the vehicle velocity accordingly.

Localization and passive entry/passive start systems and methods for vehicles
Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway establishes a wireless communication link with a portable device. Sensors receive connection information about the wireless communication link that includes a channel map, a next channel for communication, a next channel time for communication, a parameter for calculating a subsequent channel, and (v) a channel hop interval indicating a time interval for communication. Each sensor receives communication packets sent from the portable device based on the connection information and measures signal information. A localization module determines a location of the portable device based on the signal information. A PEPS system performs a vehicle function including at least one of unlocking a door of the vehicle, unlocking a trunk of the vehicle, and allowing the vehicle to be started based on the location of the portable device.
