A system and method for positioning for line-of-sight and non-line-of sight environments. In some embodiments, the method includes: receiving, by a User Equipment (UE), from a first Transmission and Reception Point (TRP) of a network, a Positioning Reference Signal (PRS); and sending, by the UE, a response to the network. The sending may include sending an indicator, the indicator indicating whether the UE has performed a measurement based on the Positioning Reference Signal, received via a line-of-sight path; or the sending may include identifying a first detected path and sending a plurality of measurements to the network, the plurality of measurements including, for each of a first plurality of paths, the arrival time difference relative to the arrival time of the first detected path, the first plurality of paths not including the first detected path, and the first plurality of paths including two paths.

Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a requesting entity, a request for information relating to a channel condition of the UE. The requesting entity may comprise a base station or a location server, for example. The UE may determine information relating to the channel condition of the UE. The UE may send, to the requesting entity, the information relating to the channel condition of the UE. In some aspects, the UE may receive location assistance data from the requesting entity along with a request to perform a location measurement; the UE may perform the location measurement and send location information to the requesting entity. The location information may comprise a location measurement result, the UE's estimate of its own location, or both.

Disclosed are Methods and apparatuses for estimating one or more characteristics of the communications channel. The method comprises receiving a first wireless signal transmitted by a transmitter at a first set of frequencies in a first time slot; and receiving a second wireless signal transmitted by the transmitter at a second set of frequencies in a second time slot. The second set of frequencies partially overlaps with the first set of frequencies and the second time slot is different from the first time slot. The method further comprises jointly processing the first wireless signal and the second wireless signal to estimate the one or more characteristics of the communications channel. Corresponding apparatuses are configured to implement the methods.

A vehicle with an automatic report function includes a transmitter configured to transmit, to a server apparatus for requesting emergency dispatch, emergency information of the vehicle when a collision of the vehicle is detected or forecasted, a global navigation satellite system (GNSS) receiver configured to receive signal waves and generate a location of the vehicle, a storage configured to store the location generated by the GNSS receiver, and a controller configured to collect information from the vehicle and cause the transmitter to transmit the information as the emergency information when the collision of the vehicle is detected or forecasted. When the collision of the vehicle is detected or forecasted, the controller determines whether the location is acquirable from the GNSS receiver and, when the location is not acquirable, collects a previously generated location and causes the transmitter to transmit the previously generated location to the server apparatus.

A method for operating a plurality of antennas of a vehicle is disclosed, in which the vehicle communicates wirelessly with an external radio station while traveling through a radio cell of the external radio station by means of a radio signal emitted by the plurality of antennas. The vehicle includes a plurality of antennas and a controller operatively connected to the antennas.

A wireless device (12A) is configured to determine, for each of one or more links (14), one or more characteristics associated with wireless device positioning performance on the link. In some embodiments, the one or more characteristics include one or more of: geometric dilution of precision, GDOP, characteristics associated with the link; or line-of-sight, LOS, characteristics or non-LOS characteristics of the link. Regardless, the wireless device (12A) may also be configured to transmit control signaling (22) indicating the one or more characteristics determined for each of the one or more links (14). Based on this control signaling (22), a network node (16) may adapt positioning reference signal, PRS, configuration on at least one of the one or more links (14).

Systems and methods are described for classification of interference for GNSS receivers. One or more neural networks are utilized to classify RF signal data received by a GNSS receiver.
