Achieving Energy-Efficient Uplink URLLC with MIMO-Aided Grant-Free Access
Linlin Zhao, Shaoshi Yang, Xuefen Chi +2
The optimal design of the energy-efficient multiple-input multiple-output (MIMO) aided uplink ultra-reliable low-latency communications (URLLC) system is an important but unsolved…
Secure Visible Light Communications via Intelligent Reflecting Surfaces
Lei Qian, Xuefen Chi, Linlin Zhao +1
Intelligent reflecting surfaces (IRS) can improve the physical layer security (PLS) by providing a controllable wireless environment. In this paper, we propose a novel PLS techniqu…
User-Centric Secure Cell Formation for Visible Light Networks with Statistical Delay Guarantees
Lei Qian, Xuefen Chi, Linlin Zhao +2
In next-generation wireless networks, providing secure transmission and delay guarantees are two critical goals. However, either of them requires a concession on the transmission r…
Optimal ALOHA-like Random Access with Heterogeneous QoS Guarantees for Multi-Packet Reception Aided Visible Light Communications
Linlin Zhao, Xuefen Chi, Shaoshi Yang
There is a paucity of random access protocols designed for alleviating collisions in visible light communication (VLC) systems, where carrier sensing is hard to be achieved due to…
