...Given all the beamforming vectors, the combining vector w1 is defined as w1 = 〈 M1H[R,1]v[2,1] 〉 , (32) where 〈x〉 = x|x| denotes the normalization operation on vector x and M1 = I − G1(GH1 G1)−1GH1 , (33) G1 = [ H[R,2]v[3,2],H[R,3]v[1,3] ] ....

...Therefore, with a proper normalization/scaling, we can take the first n elements of q7 to obtain u1, the next m elements for v[2,1] and the last m elements for v[1,2]....
[...]
...Therefore, u1, v[2,1] and v[1,2] are uniquely determined during the MA stage....
