Techniques for a non-unitary precoding scheme for wireless communications are described. An apparatus may comprise a mobile device for a mobile broadband communications system utilizing an orthogonal frequency-division multiple access technique. The mobile device may have a channel state information module operative to generate channel state information for a fixed device using a non-unitary precoding scheme for a closed loop multi-user multiple-input and multiple-output scheme. The channel state information may comprise channel quality information and a codeword index. Other embodiments are described and claimed.
