Impact of Terrestrial Blockage on the Coverage of Integrated Satellite-Terrestrial Networks
Joon-Young Park, Byungju Lim, Young-Chai Ko
The integration of non-terrestrial networks (NTNs) with terrestrial networks (TNs) is an important step toward ubiquitous connectivity in sixth-generation (6G). Despite growing int…
Multi-Agent Q-Learning for Real-Time Load Balancing User Association and Handover in Mobile Networks
Alireza Alizadeh, Byungju Lim, Mai Vu
As next generation cellular networks become denser, associating users with the optimal base stations at each time while ensuring no base station is overloaded becomes critical for…
Joint Pilot Design and Channel Estimation using Deep Residual Learning for Multi-Cell Massive MIMO under Hardware Impairments
Byungju Lim, Won Joon Yun, Joongheon Kim +1
In multi-cell massive MIMO systems, channel estimation is deteriorated by pilot contamination and the effects of pilot contamination become more severe due to hardware impairments.…
Joint Association and Resource Allocation for Multi-Hop Integrated Access and Backhaul (IAB) Network
Byungju Lim, Ju-Hyung Lee, Jae-Hong Kwon +1
Integrated access and backhaul (IAB) network is envisioned as a novel network architecture for increasing the network capacity and coverage. To facilitate the IAB network, the appr…
Attention-based Reinforcement Learning for Real-Time UAV Semantic Communication
Won Joon Yun, Byungju Lim, Soyi Jung +4
In this article, we study the problem of air-to-ground ultra-reliable and low-latency communication (URLLC) for a moving ground user. This is done by controlling multiple unmanned…
Ultrareliable and Low-Latency Communication Techniques for Tactile Internet Services
Kwang Soon Kim, Dong Ku Kim, Chan-Byoung Chae +9
This paper presents novel ultrareliable and low-latency communication (URLLC) techniques for URLLC services, such as Tactile Internet services. Among typical use-cases of URLLC ser…
