Resource Scheduling and Energy Cooperation in HetNet with Cross-Layer Interference Constraints

Algorithm 1

Resource scheduling and energy cooperation algorithm for HetNets with cross-layer interference constraints.

	Require: at time slot , get the queue states , , and the channel gain
	Output: transmission power allocation and subcarrier assignment, energy scheduling and energy cooperation
	Stage 1: resource allocation
	Initialize Lagrange multipliers , and, set
	Repeat
	For each SBS
	For each SUE
	For each subcarrier
	According to (31), calculate
	According to (35), calculate
	According to (37), calculate
	End For
	End For
	End For
	According to (32) update
	According to (33) update
	According to (38) update
	Until and or the convergence of the multipliers.
	Stage 2: Energy Scheduling and Energy Cooperation
	Solve P5 using linear programming tools, get
	Based on (41), calculate
	Update all queues
