Illustration of BS coupling, and introducing local copies to decouple a problem. BS 2 and BS 3 are coupled with BS 1 due to coupling variables z2l and z3l, respectively. To distribute the problem, local copy x1, 2l of z2l at BS 1 and local copy x2, 2l of z2l at BS 2 are introduced. Similarly, local copy x1, 3l of z3l at BS 1 and local copy x3, 3l of z3l at BS 3 are introduced.
