Abstract
An apparatus reports feedback messages for channel state information estimation with respect to a channel between a first antenna of a first device and a second antenna of a second device. The apparatus is configured to determine a frequency response across a predetermined bandwidth of the channel between the first antenna and the second antenna, sample a phase of the determined frequency response in order to obtain a number of samples of the phase of the determined frequency response, and send to a further apparatus at least a first feedback message including information of at least a subset of the obtained samples.
