Methods and apparatus for sensing-assisted doppler compensation

Aspects of the present application relate to sensing-based, mobility-aware waveform adaptation. A transmitting device may estimate a velocity vector for a mobile device. The velocity vector estimate may be based on measurements made at the mobile device and fed back to the transmitting device or based on measurements made at other devices in the environment and provided to the transmitting device. The transmitting device may, based on the estimate of the velocity vector, obtain a Doppler variable estimate for a signal path between the transmitting device and the mobile device. The transmitting device may then adapt a to-be-transmitted waveform based on the Doppler variable estimate for the signal path and then transmit the adapted waveform. Occasionally, the transmitting device may obtain updates to parameters that describe the location and mobility of the mobile device. On the basis of the updates, the transmitting device may update the waveform adaptation.
