Abstract: The user equipment (UE) of an antenna orientation detection system may receive a first set of beacon signals via an antenna at the UE. Each of the first set of beacon signals may be associated with a corresponding indication of an expected beacon location. The UE may calculate an orientation of the antenna based on the first set of beacon signals. The UE may change at least one of a position, the orientation, or a direction of the antenna and receive a second set of beacon signals. The UE may calculate at least one of a set of interfering condition parameters, a set of spoofing condition parameters, or a set of non-line-of-sight (NLOS) condition parameters based on the first set of beacon signals and the second set of beacon signals.

Abstract: Differing operations of a wireless communication device benefit from different antenna configurations, such as for positioning, where closely spaced antennas are desirable, and data communication, where antenna diversity is desirable. A device is configured to receive a request for receive a request for determining a position of a user equipment (UE), select one of a first plurality of antennas or a second plurality of antennas for determining the position of the UE, receive wireless signals using the selected first plurality of antennas or the second plurality of antennas, and determine the position of the UE based at least in part on the received wireless signals.

Abstract: A method for inhibiting jammed signal use includes: receiving a desired signal wirelessly at a receiver; receiving an undesired signal wirelessly at the receiver, the undesired signal varying in strength over time; and inhibiting measurement of the desired signal, or use of a measurement of the desired signal, based on a determination that the undesired signal is a jamming signal based on a variation of the undesired signal being indicative of jamming.

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: A method for locating a target object includes: determining a plurality of position-orientation-distance-angle values, each including: a position of a user equipment (UE) relative to a reference position; an orientation of the UE relative to a reference orientation; a distance corresponding to the position of the UE, the distance being between the position of the UE and the target object based on wireless ranging signal(s) between the UE and the target object; and an angle corresponding to the position and orientation of the UE, the angle being an AoA of the wireless ranging signal(s) at a first and second antenna of the UE, where a combination of the position and orientation of the UE in each of the position-orientation-distance-angle values is different; and calculating a position of the target object using the plurality of position-orientation-distance-angle values, where the position of the target object is relative to the reference position.

Abstract: Certain aspects of the present disclosure provide techniques reducing wireless interference in wireless communications networks by, for example, enabling a coexistence period during which transmission over a first wireless communication band is deprioritized and reception over a second wireless communication band, different from the first wireless communication band, is prioritized; and receiving positioning data from a positioning system via the second wireless communication band during the coexistence period.

Abstract: Techniques are provided for improving ranging accuracy of ultrawideband (UWB) devices. An example method for obtaining a distance measurement with a wireless node includes obtaining a first distance measurement using a first radio link, determining a status of a second radio link in response to the first distance measurement being less than a threshold distance, configuring one or more transceiver parameters associated with the second radio link in response to determining the second radio link is utilizing a non-line of sight path, and obtaining a second distance measurement using the second radio link and the one or more transceiver parameters.

Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a first user equipment (UE) can receive positioning data corresponding to a second UE. In some cases, the first UE can determine a relative position between the first UE and the second UE. In some aspects, the first UE can determine a first location estimate of the first UE based on the positioning data corresponding to the second UE and the relative position between the first UE and the second UE.
