Determine a doppler shift and report it to L2. Compensate channel estimates and data symbols with the doppler shift. Equalize and demodulate the PUCCH. Perform a first level of phase correction on the PUSCH by correcting the phase on output samples of an IDFT from the doppler shift received from L2. Measure a phase deviation on the output of the first level of phase correction, accumulate the measured phase deviation and the doppler shift received from L2, to derive an accumulated phase correction, and report the accumulated phase correction to L2. Demodulate the PUSCH.
