摘　　要：This paper explores the non-uniform distribution property of interference from the perspective of green communications. An interference migration strategy with concurrent transmission is proposed to transfer the interference among different interference regions. In particular, an interference intensity index is used to depict the non-uniform interference distribution. Then we derive the threshold for executing interference migration and the optimal transmission splitting probabilities for energy efficiency（EE） maximization. The results demonstrate that our strategy significantly improves the EE.This paper explores the non-uniform distribution property of interference from the perspective of green communications.
