| Abstract: |
| Ultra-dense small cell networks(SCNs) play an important role in satisfying people's demand of higher quality wireless communications services. This paper summarizes the development vision and corresponding key technologies in the fifth-generation mobile communications(5G),analyzes the important role and challenges of small cell networks in future wireless communications systems and gives corresponding solutions,and proposes solutions for solving problems exiting in uplink/downlink communications when the small cell networks coexist with macro networks. The related contents and suggestions can provide clear reference for the further development of small cell networks. |
