Abstract: A wireless device may receive a first set of beacon messages from a first set of proximity devices. The wireless device may measure the first set of beacon messages. The wireless device may calculate a first position estimate of the wireless device based on the measured first set of beacon messages and a first set of locations associated with the first set of proximity devices. The wireless device may transmit the first position estimate. The wireless device may receive a second set of beacon messages from a subset of a second set of proximity devices based on the first position estimate. The wireless device may measure the second set of beacon messages. The wireless device may calculate a second position estimate based on the measured second set of beacon messages and a second set of locations associated with the subset of the second set of proximity devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmission device may receive sensing information. The transmission device may transmit a radio frequency (RF) signal configured to power an RF energy harvesting device based at least in part on the sensing information satisfying a condition associated with a presence of an object. Numerous other aspects are described.

Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity obtains a set of error distributions associated with a set of locations associated with an environment, wherein each error distribution of the set of error distributions indicates an expected error distribution of positioning measurements associated with a corresponding location of the set of locations, obtains one or more positioning measurements obtained by a user equipment (UE) located within the environment; and determines a location estimate of the UE within the environment based on a comparison of uncertainty values associated with the one or more positioning measurements to the set of error distributions.

Abstract: Various embodiments may provide systems and methods for determining a distance to a short in a two-conductor wire. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a phase difference between a phase of an injected tone and a phase of a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on both a phase difference and an amplitude difference between an injected tone and a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a measured peak voltage of a combined pulse.
