摘要： Systems, methods, and devices for sidelink positioning determination and communication can employ techniques including obtaining, at a first sidelink-enabled device, data from one or more data sources indicative of one or more criteria for using either round-trip time (RTT)-based positioning of a target node or single-sided (SS)-based positioning of the target node. The techniques also include selecting, with the first sidelink-enabled device, a positioning type from the group may comprise of RTT-based positioning and SS-based positioning, based on the data. The techniques also include sending a message from the first sidelink-enabled device to a second sidelink-enabled device, where the message includes information indicative of the selected positioning type.

摘要： Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) sends, to a first entity, first information indicating a maximum number of positioning signal transmissions or a maximum power for positioning signal transmissions that the UE can support. The UE receives, from the first entity, configuration information for changing a positioning mode of the UE to a positioning mode selected from a first positioning mode and a second positioning mode. The UE performs a positioning operation according to the selected positioning mode. In some aspects, the first positioning mode is a normal positioning mode in which the UE sends UL positioning reference signals to a plurality of TRPS, and the second positioning mode is a UL power-limited mode in which the UE sends UL positioning reference signals to only one or a small number of TRPs.

摘要： Embodiments include methods for a network node or function (NNF) configured to facilitate positioning of a user equipment (UE) based on measurements of cellular radio access technology (RAT) signals and of non-cellular ranging (e.g., UWB) signals. Such methods include sending the following information to the UE: first assistance data that identifies one or more non-cellular ranging devices associated with a wireless network, and second assistance data that identifies one or more cellular RAT transmitters of the wireless network. Such methods include receiving the following information from the UE: first measurements of non-cellular ranging signals transmitted by the one or more non-cellular ranging devices identified by the first assistance data, and second measurements of cellular signals transmitted by the one or more cellular RAT transmitters identified by the second assistance data. Other embodiments include complementary methods for a UE and for a non-cellular ranging device.Figure 19 is selected for publication.

摘要： A system for accessing or providing operational control of a vehicle includes initiator and sniffer devices. The initiator device includes: polarized antennas; a transmitter transmitting a first tone signal via the polarized antennas from the vehicle to a responder/portable access device; and receiver receiving a second tone signal from the responder device in response to the first tone signal. The sniffer device includes: second polarized antennas; and a second receiver receiving, via the second polarized antennas, the first tone signal from the transmitter and the second tone signal from the responder device. The sniffer device determines states of the first and second tone signals including respective phase delays. The initiator or sniffer device estimates a first distance from the vehicle to the responder device or a second distance from the responder device to the sniffer device based on the states including respective phase delays.

摘要： Monostatic radar (314) with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal (350) for a first duration (302) and receives a first reflection (324) of the first signal from a first object (316) during a second duration (304). The system transmits a second signal (352) for a third duration (306) longer than the first duration and receives a second reflection (328,330) of the second signal from a second object (318) during a fourth duration (308). The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects (316) within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects (318) between the first distance and a second distance from the system.
