Abstract
One example discloses a method for beamforming feedback reduction in a WLAN (wireless local area network), including: generating a per-tone beamforming feedback matrix by vectorizing a set of steering vectors using vectorization based dimension reduction (DR-Vec); performing lossy compression on the vectors; reducing the per-tone beamforming feedback matrix to one vector; and generating per-tone beamforming angle information using only the one vector.
