Read moreLearning-Based Multiuser Scheduling in MIMO-OFDM Systems with Hybrid Beamforming
We investigate the multiuser scheduling problem in multiple-input multiple-output (MIMO) systems using orthogonal frequency division multiplexing (OFDM) and hybrid beamforming in which a base station (BS) communicates with multiple users…
Read moreOptimizing Effectiveness-Aware Information Exchange for Goal-Oriented Semantic Communication
The traditional maximalist approach to designing communication systems is increasingly misaligned with today's evolving connectivity demands. Cyber-physical systems require a shift toward real-time multimodal communication, autonomous decision-making, and efficient distributed…
Read morePull-Based Query Scheduling for Goal-Oriented Semantic Communication
This paper addresses query scheduling for goal-oriented semantic communication in pull-based status update systems. We consider a system where multiple sensing agents (SAs) observe a source characterized by various attributes…
Read moreIntegrated Push-and-Pull Update Model for Goal-Oriented Effective Communication
This paper studies decision-making for goal-oriented effective communication. We consider an end-to-end status update system where a sensing agent (SA) observes a source, generates and transmits updates to an actuation…
Read moreGoal-Oriented Multiple Access Connectivity for Networked Intelligent Systems
We design a self-decision goal-oriented multiple access scheme, where sensing agents observe a common event and individually decide to communicate the event’s attributes as updates to the monitoring agents, to…
Read moreEffective Communication: When to Pull Updates?
We study a pull-based communication system where a sensing agent updates an actuation agent using a query control policy, which is adjusted in the evolution of an observed information source…
Read moreSemantic Filtering and Source Coding in Distributed Wireless Monitoring Systems
The problem of goal-oriented semantic filtering and timely source coding in multiuser communication systems is considered here. We study a distributed monitoring system in which multiple information sources, each observing…
Read moreSemantic Source Coding for Two Users with Heterogeneous Goals
We study a multiuser system in which an information source provides status updates to two monitors with heterogeneous goals. Semantic filtering is first performed to select the most useful realizations…
Read moreHigh-Speed Trains Access Connectivity Through RIS-Assisted FSO Communications
Free-space optic (FSO) is a promising solution to provide broadband Internet access for high-speed trains (HSTs). Besides, reconfigurable intelligent surfaces (RIS) are considered as hardware technology to improve the performance…
