CPC Class H04W

The present disclosure relates to an electronic device and a method for performing ranging through a UWB communication including receiving state information of each of moving nodes occupying channels provided by anchor nodes in a UWB communication area to perform ranging on the anchor nodes, setting priorities of the moving nodes based on the state information, and recovering one of the channels occupied by the moving nodes based on each of the priority.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a reflection of a first radar waveform transmitted by the first UE. The UE may receive a second radar waveform from a second UE, wherein the second radar waveform is a direct transmission from the second UE or a reflection of the direct transmission. The UE may perform target detection based at least in part on the reflection of the first radar waveform and on the second radar waveform. Numerous other aspects are described.

An assistance system modifies an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication. A method includes receiving, by a remote vehicle, a request message inquiring what additional identifying information of an ego vehicle the remote vehicle requests so that the remote vehicle has a capacity to identify the ego vehicle as a transmitter of a V2X message. The method includes transmitting a response message including response data that describes the additional identifying information of the ego vehicle that provides the remote vehicle with the capacity to identify the ego vehicle as the transmitter of the V2X message when the ego vehicle is among a plurality of vehicles. The method includes receiving the V2X message that includes assistance data describing the additional identifying information. The method includes modifying the operation of the vehicle component of the remote vehicle based on the assistance data.

A location information server includes: an acquisition unit configured to acquire received signal strengths of radio signals transmitted from a transmitter and received at a receiver; an estimation unit configured to estimate a location of the transmitter or receiver, using at least the top three received signal strengths among the acquired received signal strengths; and a reliability calculation unit configured to calculate a reliability of the location estimation based on the received signal strengths that have been used.
