Network before optimization (default operation). (a) Example 1: users are concentrated and fewer than BS. (b) Example 2: users are distributed and fewer than BS. (c) Example 3: more users than BS. Performance measure: i) system throughput, and ii) power efficiency. There are two orthogonal channels represented by solid-magenta and dashed-black lines.
