Tools and methods for UE environment mapping

Abstract

A wireless communication device, WCD, transmits one or more uplink transmissions, obtains backscattering measurements for the one or more uplink transmissions, and reports the backscattering measurements to a wireless communication network. A network node in the wireless communication network receives the backscattering measurements, and estimates an environment of the WCD based on the backscattering measurements. The one or more uplink transmissions may for example include a sounding reference signal, SRS. The network node may for example schedule a transmission, select beamforming, or adapt a positioning reference signal configuration based on the estimated environment of the WCD. The network node may for example receive positioning measurements and estimate a position of the WCD based on the positioning measurements. The estimation of a position of the WCD and the estimation of an environment of the WCD may for example be performed jointly via simultaneous localization and mapping, SLAM.
