Reliability-Oriented Design Framework in NOMA-Assisted Mobile Edge Computing

IEEE Access, 2022
In this paper, we consider mission-critical task offloading in the non-orthogonal multiple access (NOMA)-assisted mobile edge computing (MEC) networks, where local information collected from multiple local devices are processed at the MEC node.

A Constrained Deep Reinforcement Learning Framework for Beamforming Optimization With QoS Guarantees in RIS‐Assisted Symbiotic Radio Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
To address the complex constrained optimization in time‐varying reconfigurable intelligent surface–assisted symbiotic radio networks, this paper proposes a novel deep reinforcement learning (DRL) approach integrating Lagrange dual optimization into deep deterministic policy gradient framework.

Transition‐Aware Q‐Learning for Robust Tracking in Networked Control Systems with Fading Channels: Application to Leader−Follower Vehicle Control

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
Maintaining reliable tracking control in networked control systems over fading wireless channels is difficult due to the stochastic and time‐correlated nature of wireless links. This work proposes a transition‐aware Q‐learning (TA‐QL) method that learns robust control policies directly from networked data without requiring explicit models, while ...

Block Error Rate Minimization of Downlink MIMO‐NOMA With Finite Blocklength

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper investigates the downlink multiple‐input multiple‐output (MIMO)‐non‐orthogonal multiple access (NOMA) transmission with finite blocklength (FBL). Our aim is to achieve the minimum average block error rate (BLER) by proposing an efficient power, rate, and blocklength allocation scheme.

Finite-blocklength Fluid Antenna Systems

CoRR
This paper investigates fluid antenna systems (FASs) subject to finite-blocklength (FBL) constraints, motivated by the strict reliability-latency and ultra-massive connectivity requirements of future wireless networks. While FAS performance has been widely studied in the asymptotic regime, its behavior under FBL remains largely unexplored.

Energy‐Efficient UAV‐Assisted Covert Communication in WSN With Finite Blocklength

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper proposes a jointly optimizing UAV trajectory and wake‐up scheduling method (JOUTWUSM) for finite blocklength covert communication in wireless sensor networks. By optimizing the UAV's trajectory and sensor node wake‐up scheduling, the method effectively balances energy efficiency and communication reliability under finite blocklength ...

SWIPT‐Enabled Full‐Duplex Short Packet Communications With Nonlinear Energy Harvesting

International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
In this work, we examine a simultaneous wireless information and power transfer (SWIPT)–enabled full‐duplex (FD) short packet communication system in which both users are equipped with a pair of transmitter–receiver antennas and can transmit and receive simultaneously.

Block-fading channels with delayed CSIT at finite blocklength [PDF]

2014 IEEE International Symposium on Information Theory, 2014
In many wireless systems, the channel state information at the transmitter (CSIT) can not be learned until after a transmission has taken place and is thereby outdated. In this paper, we study the benefits of delayed CSIT on a block-fading channel at finite blocklength.
