Hyper-dense small cell networks have been recognized as one of the most effective ways to enhance spectrum and energy efficiency. However, performance enhancement can be significantly degraded due to inter-cell interference and traffic loading imbalance. Optimal cooperation has been widely used to tackle these problems by exploring and exploiting cooperative gains. Various potential cooperation opportunities...
Extensive deployment of heterogeneous small cells over existing macrocell cellular networks forms the Ultra-dense Small cell Network (USN). USN has emerged as a key networking architecture in 5G wireless networks. It can improve network coverage and boost system capacity. However, the dense overlapped deployment of small cells leads to a complex interference problem. In this paper, we jointly implement...
