Multi-Agent DRL Approach for Energy-Efficient Resource Allocation in URLLC-Enabled Grant-Free NOMA Systems

Autor: Duc-Dung Tran, Shree Krishna Sharma, Vu Nguyen Ha, Symeon Chatzinotas, Isaac Woungang

Publikováno v: IEEE Open Journal of the Communications Society, Vol 4, Pp 1470-1486 (2023)

Grant-free non-orthogonal multiple access (GF-NOMA) has emerged as a promising access technology for the fifth generation and beyond wireless networks that enable ultra-reliable and low-latency communications (URLLC) to ensure low access latency and

End-to-End Network Slicing in Virtualized OFDMA-Based Cloud Radio Access Networks

Autor: Vu Nguyen Ha, Long Bao Le

Publikováno v: IEEE Access, Vol 5, Pp 18675-18691 (2017)

We consider the resource allocation for the virtualized OFDMA uplink cloud radio access network (C-RAN), where multiple wireless operators (OPs) share the C-RAN infrastructure and resources owned by an infrastructure provider (InP). The resource allo

Resource Allocation Optimization in Multi-User Multi-Cell Massive MIMO Networks Considering Pilot Contamination

Autor: Tri Minh Nguyen, Vu Nguyen Ha, Long Bao Le

Publikováno v: IEEE Access, Vol 3, Pp 1272-1287 (2015)

In this paper, we study the joint pilot assignment and resource allocation for system energy efficiency (SEE) maximization in the multi-user and multi-cell massive multi-input multi-output network. We explicitly consider the pilot contamination effec
