Abstract: A ranging method includes: receiving, at a first UE from a first entity, encryption input information; communicating, by the first UE with a second entity that is a second UE, to establish a ranging session with the second UE; using the encryption input information to produce an en-crypted ranging signal; and using the encrypted ranging signal in the ranging session for ranging between the first UE and the second UE.

Abstract: In some implementations, an ultra-wideband (UWB) management server may send a first message to a UWB anchor, wherein: the first message is indicative of a first threshold to use in a UWB positioning session, the first threshold specifying at least one trigger condition for making available one or more reserved time slots in a Contention Access Period (CAP) of the UWB positioning session. The UWB management server may determine a second threshold for identifying a UWB responder having a respective reserved time slot in the CAP. The UWB management server may send a second message to the UWB anchor, wherein the second message causes the UWB anchor to either: (i) move the respective reserved time slot in the CAP for the UWB responder to a respective one or more time slots in a Contention Free Period (CFP), or (ii) terminate the UWB positioning session with the UWB responder.

Abstract: Aspects presented herein may improve the efficiency and accuracy of ranging operations, such as ranging operations based on ultra-wideband or sidelink. In one aspect, a first wireless device receives a response message from at least one second wireless device, the response message including a clock accuracy value of the at least one second wireless device, a location confidence value of the at least one second wireless device, or a combination thereof. The first wireless device establishes a ranging session with the at least one second wireless device based on the clock accuracy value of the at least one second wireless device exceeding a clock accuracy threshold, or the location confidence value of the at least one second wireless device exceeding a location confidence threshold, or both.

Abstract: Various methods and apparatus for supporting positioning of a user equipment (UE) in a wireless network are disclosed. In some embodiments, a wireless network node may be configured to define one or more groups of antennas associated with a wireless network node, each of the one or more groups of antennas grouped according to at least a phase-based parameter correlated with an electromagnetic characteristic of a plurality of antennas; send, to a network entity, data identifying the defined one or more groups of antennas; receive configuration data from the network entity, the configuration data identifying at least one of the one or more groups of antennas; and based on the configuration data, send or receive reference signals with the wireless network node using the identified at least one of the one or more groups of antennas, the reference signals configured to be used in the positioning of the UE.

Abstract: In some implementations, a current synchronization reference anchor for the group of RF positioning anchors may obtain metric information from each radio frequency (RF) positioning anchor of the group of RF positioning anchors. The current synchronization reference anchor may select the new synchronization reference anchor from the group of RF positioning anchors based at least in part on the metric information.

Abstract: A first user equipment (UE) may transmit a first ranging message. A second UE may receive the first ranging message. The second UE may calculate a carrier frequency offset (CFO) based on the ranging message. The second UE may transmit a response message comprising control information to modify a transmission protocol. The transmission of the response message may be in response to the calculated CFO being greater than or equal to a threshold value. The calculated CFO may indicate a possible security vulnerability between the first UE and the second UE. The first UE may receive the response message including control information to modify the transmission protocol after the transmission of the first ranging message. The first UE may then transmit a second ranging message based on the control information. The second ranging message may prevent, or mitigate, the detected possible security vulnerability.

Abstract: A system for radio frequency (RF) residual sideband (RSB) calibration includes a complex (in phase/quadrature (I/Q)) signal receiver, a signal generator configured to generate a transmit (Tx) signal, a first phase shifter operably coupled to the real signal transmitter, a first signal combiner configured to combine a receive (Rx) signal with the transmit (Tx) signal to generate a first combined signal, a second phase shifter configured to provide a selected phase shift to the first combined signal, and a complex downconverter configured to generate an in phase Rx signal and a quadrature Rx signal alternatively using an in phase LO signal and a quadrature LO signal to generate one or more signals indicative of relative Tx-Rx LO phase (θ), amplitude (A), Tx LO I/Q phase mismatch (ε), Rx I/Q amplitude mismatch (α), and Rx I/Q phase mismatch (φ) at the output of the complex receiver.

Abstract: An example signal transfer method includes: determining, at a first apparatus, whether to transmit an ultra-wideband physical-layer signal with a first configuration or a second configuration based on an application for transfer of the ultra-wideband physical-layer signal, the first configuration being different from the second configuration; and transmitting, from the first apparatus to a second apparatus, the ultra-wideband physical-layer signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an initiating device may transmit a signal that includes multiple packets. The initiating device may receive, from a responding device, a channel impulse response (CIR) report for each packet of the multiple packets. The initiating device may align, using one or more taps in the CIR report for each packet, the CIR reports across the multiple packets to identify a target object, a location of the target object, or a movement of the target object. The initiating device may perform an action based at least in part on the target object, the location of the target object, or the movement of the target object. Numerous other aspects are described.
