Abstract
A method and apparatus may include measuring a space frequency downlink channel matrix. The space frequency downlink channel matrix reflects a channel response observed by the apparatus. The apparatus receives transmissions from an array of antennas of a network node. The method can also include determining a spatial channel vector. The method can also include determining scalar phase terms. The method can also include determining a Signal-to-Interference-Plus-Noise-Ratio scalar factor of the channel response observed by the apparatus. The method can also include transmitting an encoded form of the spatial channel vector. The method can also include transmitting an encoded form of the Signal-to-Interference-Plus-Noise-Ratio scalar factor. The method can also include transmitting an encoded form of the scalar phase terms.
