Energy-Spectral Efficiency Trade-Offs in Full-Duplex MU-MIMO Cloud-RANs with SWIPT

Algorithm 1

The iterative algorithm for the sum-SE maximization (or sum-power consumption minimization) problem.

Initialization: Setting the small error tolerance , the maximum number of iteration . Generating an initial set by solving max-min problem (58a) and (58b);

Set ;

 Find optimal set by solving convex problem (50a) and (50b) [or (51a) and (51b)],

 Update and ;

until reaches with [or ];

Output: The optimum point .
