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: 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.
