A Hybrid Optimization and Deep RL Approach for Resource Allocation in Semi-GF NOMA Networks
Duc-Dung Tran, Vu Nguyen Ha, Symeon Chatzinotas +1
Semi-grant-free non-orthogonal multiple access (semi-GF NOMA) has emerged as a promising technology for the fifth-generation new radio (5G-NR) networks supporting the coexistence o…
Two-tier User Association and Resource Allocation Design for Integrated Satellite-Terrestrial Networks
Hung Nguyen-Kha, Vu Nguyen Ha, Eva Lagunas +2
This paper presents a study of an integrated satellite-terrestrial network, where Low-Earth-Orbit (LEO) satellites are used to provide the backhaul link between base stations (BSs)…
Large-Scale Beam Placement and Resource Allocation Design for MEO-Constellation SATCOM
Vu Nguyen Ha, Eva Lagunas, Tedros Salih Abdu +3
This paper presents a centralized framework for optimizing the joint design of beam placement, power, and bandwidth allocation in an MEO satellite constellation to fulfill the hete…
LEO-to-User Assignment and Resource Allocation for Uplink Transmit Power Minimization
Hung Nguyen-Kha, Vu Nguyen Ha, Eva Lagunas +2
This paper aims to develop satellite-user association and resource allocation mechanisms to minimize the total transmit power for integrated terrestrial and non-terrestrial network…
GEO Payload Power Minimization: Joint Precoding and Beam Hopping Design
Vu Nguyen Ha, Ti Ti Nguyen, Eva Lagunas +2
This paper aims to jointly determine linear precoding (LP) vectors, beam hopping (BH), and discrete DVB-S2X transmission rates for the GEO satellite communication systems to minimi…
