Abstract:
1. A method comprising: determining, by a receiver, at least part of a maximum ratio combining (MRC) vector based on stored channel data and at least part of a first maximum ratio transmission (MRT) vector based on stored channel data; receiving, by the receiver, a first sounding vector based on the at least part of the first MRT vector and a second sounding vector utilizing the MRC vector, wherein the MRC vector is determined based on the at least part of the MRC vector and measurement of the first sounding vector; determining, by the receiver, a parameter of the second sounding vector; transmitting, by the receiver, the parameter back to a source; and receiving, by the receiver, a directional transmission based on the parameter and the first MRT vector, wherein beamforming is terminated when a predetermined condition is met.
