Presented herein are techniques for GPS attack prevention in association with wireless communication devices. In at least one embodiment, a method may include receiving, at a mobile device from a first access point (AP), first location information and one or more of a first token or first neighbor information relating to neighboring APs. The mobile device may receive from a second AP, second location information and one or more of a second token or second neighbor information relating to neighboring APs. The first token may be compared to the second token to determine whether the first and second tokens are consistent, and/or the first neighbor information may be compared to the second neighbor information to determine whether the first and second neighbor information are consistent. It may be determined whether the first location information provided by the first AP and the second location information provided by the second AP are valid based on the comparison(s).

A method of operating a wireless device in a wireless communication network includes receiving a first reference signal at a first reception time from a first network node, receiving a second reference signal at a second reception time from a second network node, receiving a first indication of a first reference time, receiving a second indication of a second reference time, and transmitting a report to a serving network node. The indications of the first and second reference times indicate timings of frame structures of the first and second network nodes, respectively. The report is based on a first representation of a difference between the first reception time and the second reception time. The first representation is further based on the indications of the first and second reference times. Also provided are related devices and methods.

A method, performed by a network node, is disclosed for handling positioning of a User Equipment, wireless device. The network node obtains a first approximate position of the wireless device, based on a first positioning procedure for the wireless device in a first frequency allocation. The network node determines, based on the first approximate position of the wireless device, a set of resources to be used for a second positioning procedure in a second frequency allocation. The network node initiates the second positioning procedure in the second frequency allocation using the determined set of resources. The network node obtains an updated position of the wireless device based on the second positioning procedure.

The present disclosure relates to a sidelink positioning method in a vehicle equipped with a distributed antenna, and a device therefor. A sidelink positioning method in a user equipment (UE) of a positioning vehicle equipped with a distributed antenna according to one aspect may comprise the steps of: performing a preliminary operation for sidelink positioning to select a nearby vehicle which is to participate in the positioning; exchanging, with the selected nearby vehicle, sidelink control information for the positioning; reselecting an antenna group, which is to participate in the positioning, on the basis of a signal received from the selected nearby vehicle; and performing the positioning using the reselected antenna group. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station (BS) or a network.

This application provides example positioning methods and example apparatuses. One example method includes sending, by a positioning management network element, a positioning measurement request to a positioning measurement network element. The positioning measurement request is used to request the positioning measurement network element to feed back channel state information of a terminal device. Then, the positioning management network element receives a positioning measurement response from the positioning measurement network element. The positioning measurement response includes the channel state information of the terminal device. Then, the positioning management network element determines a location of the terminal device based on the channel state information of the terminal device.

Certain aspects of the present disclosure provide techniques for sensing window configuration for sidelink based ranging and positioning. For example, during sidelink-based ranging or sensing, a user equipment (UE) may determine the relative distance or position with other UEs. This may be realized by a UE broadcasting a wideband position reference signal (PRS) on an unlicensed band and measuring the round-trip time associated with a peer UE's PRS. The measurement accounts for a PRS transmission time transmitted by each UE. The UE may apply a sensing window to determine whether a neighboring UE has reserved PRS transmission times. The present disclosure provides methods and techniques for a network entity to configure a sensing window in a UE so that the UE may determine, during the sensing window, whether neighboring UEs have reserved a PRS transmission time.
