In federated learning (FL) over the 5G system (5GS), a group of user equipments (UEs) that are FL participants with diverse local datasets can accelerate the model training and enhance the model generalization. It is impractical to blindly select a large number of FL participants in order to derive a well-trained model. Instead, it would be more beneficial to select a small number of FL participan...Show More
Mobile edge computing (MEC) is considered a more effective technological solution for developing the Internet of Things (IoT) by providing cloud-like capabilities for mobile users. This article combines wireless powered communication (WPC) technology with an MEC network, where a base station (BS) can transfer wireless energy to edge users (EUs) and execute computation-intensive tasks through task ...Show More
Without any radiation control measures, a large-scale mmWave antenna array at close range may lead to a large amount of electromagnetic exposure of human. In this paper, with the aid of pose detection in computer vision, a beamforming scheme using a novel exposure avoidance method is proposed in outdoor line of sight scenarios. Instead of reducing transmitted power, the proposed method can protect...Show More
Fog radio access networks (F-RANs) can effectively alleviate fronthaul loads and reduce content transmission delay by migrating cloud services to the network edge. This paper addresses a cooperative caching scenario in F-RAN, where each mobile user can acquire the requested contents from any one of its associated fog-computing-based access points (F-APs). However, caching disparate contents in dif...Show More
In the fifth generation (5G) network, the Cloud Radio Access Network (C-RAN) architecture is considered as a promising technology. In the typical C-RAN network, the base station is decoupled into Baseband Unit (BBU) and Remote Radio Head (RRH). In order to achieve higher flexibility and better resource utilization ratio, the BBU is further split into Centralized Unit (CU) and Distributed Unit (DU)...Show More
A novel location-aware beamforming scheme for millimeter wave communication is proposed for line of sight (LOS) and low mobility scenarios, in which computer vision is introduced to derive the required position or spatial angular information from the image or video captured by camera(s) colocated with mmWave antenna array at base stations. A wireless coverage model is built to investigate the cove...Show More
Cloud-Radio Access Network (C-RAN) architecture has been considered widely in wireless network research. Software Defined Radio (SDR) and Network Function Virtualization (NFV) technologies realize flexible deployments of C-RAN. In our paper, a testbed based on SDR and NFV is built for splitting C-RAN into several independent units: Centralized Unit Control Plane (CU-CP), Centralized Unit User Plan...Show More
By offloading storage and computing resources to the edge of networks, mobile edge computing (MEC) is emerged as a promising architecture to reduce the transmission delay and bandwidth waste for mobile multimedia services. This paper focuses on a multi-service scenario in the MEC systems, where the MEC server can provide three multimedia services including live streaming, buffered streaming and lo...Show More
Cloud Radio Access Network (C-RAN) is widely considered a significant part of fifth generation (5G) networks. This paper offers flexible Software Defined Radio (SDR) testbed for C-RAN researchers and developers to verify network function and evaluate system performance. In 5G C-RAN architecture, a Baseband Unit (BBU) of C-RAN is split into a Centralized Unit (CU) and a Distributed Unit (DU). As a ...Show More
Cloud radio access network (C-RAN) plays a more and more important role in next generation network researches. According to the C-RAN architecture, Base Band Units (BBUs) are centralized in a BBU pool and connected with the Remote Radio Heads (RRHs) through optical front-haul links. User Equipments (UEs) get access through the radio connection with RRHs. Much work has been done about the RRH-UE op...Show More
