Patent ID: 8824587

Claim:
A method for providing feedback channel state information, the method comprising: receiving, at a receiving device, a beam transmitted by a transmitting device; computing, at the receiving device, a channel state matrix H of the transmission channel based on the received beam; performing, at the receiving device, a singular value decomposition procedure, using the channel state matrix H, that produces: a set of angles (θ V , φ) for defining a steering matrix V; a third angle θ U ; a rotation of an R matrix, wherein the R matrix is generated based on a decomposition of the channel state matrix H; and singular values of the channel state matrix H based on the angle θ V , the third angle θ U , and the R matrix; and transmitting, by the receiving device, the set of angles (θ V , φ) to the transmitting device, wherein the steering matrix V is computable by the transmitting device based on the set of angles (θ V , φ) transmitted to the transmitting device.
