With the continuous increase of mobile Internet traffic, the user-centric ultra-dense network (UUDN) is proposed as one of the promising solutions to provide very high area throughput density and flexible access service for users. The limited radio resources cause serious competition among numerous APs. Thus, Non-orthogonal multiple access (NOMA), which supports multiple signals transmission on the...
Ultra Dense network (UDN) is considered as one of the promising and efficient communication solution for high throughput and large connection numbers scenarios. Due to the densification of the users perspective and massive-access opportunities, how to optimize the multiple users access in UDN is an important and complicated problem. The traditional multi-user access schemes may be no longer suitable...
Device-to-device (D2D) communication has been regarded as a major technology to improve spectrum utilization and to offload the traffic from cellular base station. D2D peer discovery, as a critical procedure, attracts a lot of attentions. Furthermore, combination with the mobile social network (MSN) is an efficient solution to improve the establishment of D2D pairs. However, limited work has been...
