Abstract: | Referring to research on the Heterogeneous Network (Het-Net) application scenario and technique characters in IMT-Advanced (The 4th Generation Mobile Communications) cellular system , this paper provides further analysis on main technique aspects of Heterogeneous Networking, discussion on interference issue due to multi-layer building by access points and their corresponding solutions from standardization and engineering implementation. The proposed solution can effectively solve the interference problem in IMT-advanced Het-Net, and also improve the networking performance dramatically for future mobile communication systems. |
