Uplink Resource Allocation for Interference Mitigation in Two-Tier Femtocell Networks

Algorithm 1

Macro BS operation in the heuristic scheme.

(1)	Parameter initialization(i) : slot index(ii), , : resource allocator
(2)	Compute scheduled macro MS set(i)
(3)	Choose a macro MS (i)
(4)	Time slot allocation for the macro MS (i)
(5)	Parameter update(i) and
(6)	If , go to step (7); otherwise, go back to step (4)
(7)	Update the macro MS scheduling set(i)
(8)	If , stop; otherwise, go back to step (3)
