Over-the-Air Computation for Distributed Systems: Something Old and Something New
Zheng Chen, Erik G. Larsson, Carlo Fischione +2
Facing the upcoming era of Internet-of-Things and connected intelligence, efficient information processing, computation, and communication design becomes a key challenge in large-s…
Robust Beamforming Design for IRS-Aided URLLC in D2D Networks
Jing Cheng, Chao Shen, Zheng Chen +1
Intelligent reflecting surface (IRS) and device-to-device (D2D) communication are two promising technologies for improving transmission reliability between transceivers in communic…
Treating Interference as Noise in Cell-Free Massive MIMO Networks
Shuaifei Chen, Jiayi Zhang, Zheng Chen +1
How to manage the interference introduced by the enormous wireless devices is a crucial issue to address in the prospective sixth-generation (6G) communications. The treating inter…
RIS-aided D2D Communication Design for URLLC Packet Delivery
Jing Cheng, Chao Shen, Zheng Chen +1
In this paper, we consider a smart factory scenario where a set of actuators receive critical control signals from an access point (AP) with reliability and low latency requirement…
Throughput and Age of Information in a Cellular-based IoT Network
Praful D. Mankar, Zheng Chen, Mohamed A. Abd-Elmagid +2
This paper studies the interplay between device-to-device (D2D) communications and real-time monitoring systems in a cellular-based Internet of Things (IoT) network. In particular,…
Dynamic Resource Allocation in Co-Located and Cell-Free Massive MIMO
Zheng Chen, Emil Björnson, Erik G. Larsson
In this paper, we study joint power control and scheduling in uplink massive multiple-input multiple-output (MIMO) systems with randomly arriving data traffic. We consider both co-…
Age of Information in a Multiple Access Channel with Heterogeneous Traffic and an Energy Harvesting Node
Zheng Chen, Nikolaos Pappas, Emil Björnson +1
Age of Information (AoI) is a newly appeared concept and metric to characterize the freshness of data. In this work, we study the delay and AoI in a multiple access channel (MAC) w…
When Is the Achievable Rate Region Convex in Two-User Massive MIMO Systems?
Zheng Chen, Emil Björnson, Erik G. Larsson
This letter investigates the achievable rate region in Massive multiple-input-multiple-output (MIMO) systems with two users, with focus on the i.i.d.~Rayleigh fading and line-of-si…
Channel Hardening and Favorable Propagation in Cell-Free Massive MIMO with Stochastic Geometry
Zheng Chen, Emil Björnson
Cell-Free (CF) Massive MIMO is an alternative topology for future wireless networks, where a large number of single-antenna access points (APs) are distributed over the coverage ar…
Throughput and Delay Analysis of Wireless Caching Helper Systems with Random Availability
Nikolaos Pappas, Zheng Chen, Ioannis Dimitriou
In this paper, we investigate the effect of bursty traffic and random availability of caching helpers in a wireless caching system. More explicitly, we consider a general system co…
Decentralized Opportunistic Access for D2D Underlaid Cellular Networks
Zheng Chen, Marios Kountouris
We propose a decentralized access control scheme for interference management in D2D (device-to-device) underlaid cellular networks. Our method combines SIR-aware link activation wi…
