Accelerating Heterogeneous Agent Collaboration in Dynamic Edge Networks
Tianji He, Yulin Shao, Fen Hou
Deploying large language models (LLMs) at the network edge is hindered by their enormous cost, yet the reasoning quality they provide remains indispensable. Heterogeneous collabora…
Delay-Doppler Domain Channel Estimation: What if Sparsity is Unknown?
Zijian Yang, Yulin Shao, Fen Hou +1
Sparsity in the delay-Doppler (DD) domain enables efficient channel estimation, but the realization-wise sparsity level is rarely known in advance, and it fluctuates. What if we co…
Multi-Mode Pinching-Antenna Systems: Polarization-Aware Full-Wave Modeling and Optimization
Dengke Wei, Runxin Zhang, Yulin Shao +2
Millimeter-wave and terahertz communications face a fundamental challenge: overcoming severe path loss without sacrificing spectral efficiency. Pinching antenna systems (PASS) addr…
Joint Beamforming Design and Resource Allocation for IRS-Assisted Full-Duplex Terahertz Systems
Chi Qiu, Wen Chen, Qingqing Wu +4
Intelligent reflecting surface (IRS)-assisted full-duplex (FD) terahertz (THz) communication systems have emerged as a promising paradigm to satisfy the escalating demand for ultra…
Beamforming Design for Intelligent Reffecting Surface Aided Near-Field THz Communications
Chi Qiu, Qingqing Wu, Wen Chen +4
Intelligent reflecting surface (IRS) operating in the terahertz (THz) band has recently gained considerable interest due to its high spectrum bandwidth. Due to the exploitation of…
Cost Optimization for Serverless Edge Computing with Budget Constraints using Deep Reinforcement Learning
Chen Chen, Peiyuan Guan, Ziru Chen +3
Serverless computing adopts a pay-as-you-go billing model where applications are executed in stateless and shortlived containers triggered by events, resulting in a reduction of mo…
