By the way: This overwrites G in each iteration by a growing matrix:

for t= 1:length(N_UE)
  for r = 1:length(N_SC)
    G = rand(t,r)
  end
end

Replace this by:

G = rand(length(N_UE), length(N_SC));

Please post the complete error message. It contains a clear description of the problem. I guess, that the number of elements of S and C do not match. But without further explanations, it is not clear, which one is wanted.
