Methods and apparatus for sensing-assisted doppler compensation

An apparatus comprising:

• at least one processor;
• and
• a non-transitory memory including instructions that, when executed by the at least one processor, cause the apparatus to:
• obtain an estimate of a velocity vector for a mobile device;
• obtain, based on the estimate of the velocity vector, an estimate of a Doppler variable for a signal path between the apparatus and the mobile device;
• obtain, based on the estimate of the Doppler variable for the signal path, an adapted waveform;
• and
• transmit a signal according to the adapted waveform.

A method, comprising:

• receiving, at a mobile device, a sensing reference signal;
• processing, at the mobile device, the sensing reference signal, to obtain an estimate of a velocity vector for the mobile device;
• transmitting, from the mobile device to a first device, feedback, the feedback including an indication of the estimate of the velocity vector, thereby allowing the first device to:
• obtain, based on the estimate of the velocity vector, an estimate of a Doppler variable for a signal path between the first device and the mobile device;
• and
• obtain, based on the estimate of the Doppler variable for the signal path, an adapted waveform;
• and
• receiving, at the mobile device, a signal according to the adapted waveform.
