Sub-channel and Power Allocation for Non-orthogonal Multiple Access Relay Networks with Amplify-and-Forward Protocol
Shuhang Zhang, Boya Di, Lingyang Song +1
In this paper, we study the resource allocation problem for a single-cell non-orthogonal multiple access (NOMA) relay network where an OFDM amplify-and-forward (AF) relay allocates…
Resource Allocation in Wireless Powered Relay Networks: A Bargaining Game Approach
Zijie Zheng, Lingyang Song, Dusit Niyato +1
Simultaneously information and power transfer in mobile relay networks have recently emerged, where the relay can harvest the radio frequency (RF) energy and then use this energy f…
Cost Efficiency for Economical Mobile Data Traffic Management from Users' Perspective
Jinghuan Ma, Lingyang Song, Yonghui Li
Explosive demand for wireless internet services has posed critical challenges for wireless network due to its limited capacity. To tackle this hurdle, wireless Internet service pro…
Resource Management in Non-orthogonal Multiple Access Networks for 5G and Beyond
Lingyang Song, Yonghui Li, Zhiguo Ding +1
Non-orthogonal multiple access (NOMA) schemes have been proposed for the next generation of mobile communication systems to improve the access efficiency by allowing multiple users…
D2D-U: Device-to-Device Communications in Unlicensed Bands for 5G and Beyond
Hongliang Zhang, Yun Liao, Lingyang Song
Device-to-Device (D2D) communication, which enables direct communication between nearby mobile devices, is an attractive add-on component to improve spectrum efficiency and user ex…
Sub-channel Assignment, Power Allocation and User Scheduling for Non-Orthogonal Multiple Access Networks
Boya Di, Lingyang Song, Yonghui Li
In this paper, we study the resource allocation and user scheduling problem for a downlink nonorthogonal multiple access network where the base station allocates spectrum and power…
Collaborative Smartphone Sensing using Overlapping Coalition Formation Games
Boya Di, Tianyu Wang, Lingyang Song +1
With the rapid growth of sensor technology, smartphone sensing has become an effective approach to improve the quality of smartphone applications. However, due to time-varying wire…
Caching as a Service: Small-cell Caching Mechanism Design for Service Providers
Zhiwen Hu, Zijie Zheng, Tao Wang +2
Wireless network virtualization has been well recognized as a way to improve the flexibility of wireless networks by decoupling the functionality of the system and implementing inf…
Radio Resource Allocation for Device-to-Device Underlay Communication Using Hypergraph Theory
Hongliang Zhang, Lingyang Song, Zhu Han
Device-to-Device (D2D) communication has been recognized as a promising technique to offload the traffic for the evolved Node B (eNB). However, the D2D transmission as an underlay…
Listen-and-Talk: Protocol Design and Analysis for Full-duplex Cognitive Radio Networks
Yun Liao, Tianyu Wang, Lingyang Song +1
In traditional cognitive radio networks, secondary users (SUs) typically access the spectrum of primary users (PUs) by a two-stage "listen-before-talk" (LBT) protocol, i.e., SUs se…
Source and Physical-Layer Network Coding for Correlated Two-Way Relaying
Qiang Huo, Lingyang Song, Yonghui Li +1
In this paper, we study a half-duplex two-way relay channel (TWRC) with correlated sources exchanging bidirectional information. In the case, when both sources have the knowledge o…
