To Reflect or Not To Reflect: On-Off Control and Number Configuration for Reflecting Elements in RIS-Aided Wireless Systems
Hao Xie, Dong Li
Reconfigurable intelligent surface (RIS) has been regarded as a promising technique due to its high array gain and low power. However, the traditional passive RIS suffers from the…
Exploring Hybrid Active-Passive RIS-Aided MEC Systems: From the Mode-Switching Perspective
Hao Xie, Dong Li, Bowen Gu
Mobile edge computing (MEC) has been regarded as a promising technique to support latencysensitivity and computation-intensive serves. However, the low offloading rate caused by th…
Convolutional Autoencoder-Based Phase Shift Feedback Compression for Intelligent Reflecting Surface-Assisted Wireless Systems
Xianhua Yu, Dong Li, Yongjun Xu +1
In recent years, intelligent reflecting surface (IRS) has emerged as a promising technology for 6G due to its potential/ability to significantly enhance energy- and spectrum-effici…
On Hybrid Pilot for Channel Estimation in Massive MIMO Uplink
Jiaming Li, Chau Yuen, Dong Li +2
This paper introduces a hybrid pilot-aided channel estimation technique for mitigating the effect of pilot contamination for the uplink of multi-cell multiuser massive MIMO systems…
