Claim 11:
12. The apparatus of claim 11, wherein at least one of:
the channel sounding is performed on consecutive OFDM symbols,
the channel sounding is performed using an estimation algorithm with parameters that are optimized beforehand using a machine learning algorithm and possibly on the measurement beams,
the Nr phase shifters are circularly symmetric complex Gaussian vectors,
a receive measurement codebook used for beam selection and channel estimation is based on weighted pseudo random beamforming with adaptive weight updates, the weight updates provided by the base station and adaptive to channel conditions of the sub-carrier group of the base station, or
at least one of a beamforming cookbook or the receive measurement codebook is deterministic, designed offline and is loaded when a predetermined condition is met.
