EE-eICIC: Energy-Efficient Optimization of Joint User Association and ABS for eICIC in Heterogeneous Cellular Networks

Algorithm 1

Iterative algorithm for EE-eICIC.

() Choose the error tolerance and the maximum iteration number

() Set the EE and iteration index .

() while  Convergence == false and   do

() Solve the problem OP2 for a given and obtain the EE-eICIC subframes allocation policy

() if    then

() Convergence = true;

() return the optimal EE-eICIC subframes allocation policy and maximal

() else

() set and ;

() Convergence = false.
