Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs a plurality of positioning measurements of a plurality of positioning reference signals (PRS) transmitted by at least one network node, transmits a first physical layer message having a fixed payload size, wherein the first physical layer message includes at least an indication of a type, a number, or both of a first set of positioning measurements of the plurality of positioning measurements to be included in a second physical layer message having a variable payload size, and transmits the second physical layer message having the variable payload size, wherein the second physical layer message includes at least the first set of positioning measurements, and wherein the variable payload size of the second physical layer message is based at least on the type, the number, or both of the first set of positioning measurements.

A global resource locator (GRL) device can be used to track a physical asset. The GRL device can a semiconductor chip with a processor and a timing device. The semiconductor chip can generate a timing signal. The GRL device can include a blockchain, a communication device, and a memory in logical communication with the processor. The memory can store an identifier, a public key, a private key, and a hash. The communication device can communicate wirelessly with an authenticated radio source, the micro sized timing device, and the blockchain. Each authenticated radio source can be located at a respective reference location. The communication device can receive wireless timing signals from at least three authenticated radio sources. The GRL device can be affixed to a product.

In an aspect, a UE (e.g., PUE or VUE) performs one or more sidelink positioning measurements on a first sidelink positioning signal between PUE and a VUE. The UE transmits measurement data based on the one or more sidelink positioning measurements to a RSU. The RSU receives the measurement data and determines a positioning estimate for the PUE. The RSU transmits the positioning estimate to the PUE, at least one VUE, or a combination thereof.

For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.

A method for operating an access node includes receiving motion information from a user equipment (UE) in accordance with a communications beam, determining a predicted area of the UE in accordance with the motion information, configuring multiple tracking beams in accordance with the predicted area of the UE, and sending the multiple tracking beams.

The present disclosure relates to positioning methods, systems, and apparatuses. One example method includes receiving, by a server, a first message from a first terminal device, where the first message includes first location information determined by the first terminal device, determining, by the server, a first reference object based on the first location information, and sending, by the server, a second message to the first terminal device, where the second message includes identification information of the first reference object, and the identification information of the first reference object is used by the first terminal device to update the first location information.

Mobile equipment including a geo-localization device arranged to determine a current position for the mobile equipment in a space to be mapped; a communication device arranged to communicate with access points of a local network implemented in the space to be mapped; a control component arranged: to control each access point selectively and in independent manner via the communication device so as to cause said access point to transmit a reference signal; to use the reference signals received by the communication device to evaluate respective qualities for the connections between each of the access points and the mobile equipment in the current position.

A computer-implemented method for establishing and controlling a mobile perimeter and for determining a geographic location of an RF emitting source at or within the mobile perimeter includes receiving from RF sensors in a network, processed RF emissions from the source collected at RF sensors. The RF emissions follow a wireless protocol and include frames encoding RF emitting source identification information. The method further includes extracting RF emitting source identification information from the frames, processing the source identification information to identify the RF emitting source, and classifying the RF emitting source by one or more of UAS type, UAS capabilities, and UAS model. The method also includes receiving from the RF sensors, a geographic location of each RF sensor and a time of arrival (TOA) of the RF emissions at the RF sensor; and executing a multilateration process to estimate a geographic location of the RF emitting source.

A first client station receives from an access point an indication of whether angular information is to be included in feedback information in a range measurement session. The first client station transmits a null data packet (NDP) as part of an uplink multi-user (MU) PHY transmission that also includes simultaneous transmissions by one or more second client stations of one or more other respective NDPs to the access point as part of the range measurement session. The first client station receives a downlink physical layer (PHY) data unit from the access point that includes respective downlink feedback frames for the first client station and the one or more second client stations. When angular information is to be included in the feedback, a downlink feedback frame for the first client station includes angular information.
