Abstract: A wireless power transmitter system includes: a power delivery structure comprising power transmitting elements (power transmitting elements), each of which is configured to induce a field, and configured to adapt to an exterior shape of an entity that contains a receiver; a power circuit configured to provide power to the power transmitting elements selectively; and a controller configured to: determine an electrical characteristic, other than power transfer to the receiver, associated with actuating at least one of the power transmitting elements; determine at least one power transmitting element subset, based on the electrical characteristic, containing less than all, and at least one, of the power transmitting elements; select, based on power transferred to the receiver, one or more charging power transmitting elements to use to charge the receiver wirelessly; and cause the power circuit to provide power to the one or more charging power transmitting elements.

Abstract: Disclosed are techniques for determining locations of reference nodes. In an aspect, an apparatus transmits a request to a first reference node to perform a first round-trip-time (RTT) procedure with a second reference node, determines a first distance between the first reference node and the second reference node based on the RTT procedure, determines relative locations of the first and second reference nodes with respect to each other, and determines absolute locations of the first and second reference nodes from their relative locations based on at least one of the first and second reference nodes having a known absolute location and at least one known angle-of-arrival (AoA) or angle-of-departure (AoD) of at least one reference signal.

Abstract: Techniques are provided for time-domain processing of DL-PRS signals under certain conditions in which time-domain processing has a computational advantage over frequency-domain processing. Because of this, embodiments can provide positioning at a lower computational cost than positioning provided by traditional techniques utilizing only frequency-domain processing. This reduced computational cost can improve the battery life of mobile devices, ultimately resulting in a better user experience.

Abstract: Disclosed are techniques for determining a line-of-sight (LOS) path between a transmitter and a wireless device in a wireless communications network. In an aspect, a wireless device receives, from the transmitter, a first reference signal transmitted on a first antenna port and a second reference signal transmitted on a second antenna port, the first reference signal having a first polarization and the second reference signal having a second polarization with known difference (e.g., perpendicular) to the first polarization, compares multi-path channels estimated from reception of the first reference signal and the second reference signal to multi-path channels expected from the first reference signal and the second reference signal when transmitted along the LOS path between the transmitter and the wireless device, and determines which path (if any) of the multi-path channels corresponds to the LOS path between the transmitter and the wireless device.
