Energy Efficient Reconfigurable Intelligent Surface Enabled Mobile Edge Computing Networks with NOMA
Zhiyang Li, Ming Chen, Zhaohui Yang +4
Reconfigurable intelligent surface (RIS) has emerged as a promising technology for achieving high spectrum and energy efficiency in future wireless communication networks. In this…
Effective Capacity and Power Allocation for Machine-Type Communication
Mohammad Shehab, Hirley Alves, Matti Latva-aho
Effective capacity (EC) determines the maximum communication rate subject to a particular delay constraint. In this work, we analyze the EC of ultra reliable Machine Type Communica…
Improving Wireless Physical Layer Security via D2D Communication
Hao Xu, Cunhua Pan, Wei Xu +3
This paper investigates the physical layer security issue of a device-to-device (D2D) underlaid cellular system with a multi-antenna base station (BS) and a multi-antenna eavesdrop…
Performance Analysis of User-centric Virtual Cell Dense Networks over mmWave Channels
Jianfeng Shi, Yinlu Wang, Hao Xu +2
This paper analyzes the ergodic capacity of a user-centric virtual cell (VC) dense network, where multiple access points (APs) form a VC for each user equipment (UE) and transmit d…
Robust Beamforming with Pilot Reuse Scheduling in a Heterogeneous Cloud Radio Access Network
Hao Xu, Cunhua Pan, Wei Xu +3
This paper considers a downlink ultra-dense heterogeneous cloud radio access network (H-CRAN) which guarantees seamless coverage and can provide high date rates. In order to reduce…
Robust Transmission Design for Multi-Cell D2D Underlaid Cellular Networks
Hao Xu, Gordon L. Stüber, Wei Xu +4
This paper investigates the robust transmission design (RTD) of a multi-cell device-to-device (D2D) underlaid cellular network with imperfect channel state information (CSI). The b…
Association and Load Optimization with User Priorities in Load-Coupled Heterogeneous Networks
Zhaohui Yang, Wei Xu, Jianfeng Shi +2
In this paper, we consider the network utility maximization problem with various user priorities via jointly optimizing user association, load distribution and power control in a l…
Pilot Reuse Among D2D Users in D2D Underlaid Massive MIMO Systems
Hao Xu, Wei Xu, Zhaohui Yang +2
In a device-to-device (D2D) underlaid massive MIMO system, D2D transmitters reuse the uplink spectrum of cellular users (CUs), leading to cochannel interference. To decrease pilot…
