Joint communications and sensing design for multi-carrier MIMO systems

Nguyen, Thanh Nhan; Shlezinger, Nir; Ngo, Khac Hoang; Nguyen, Van Dinh; Juntti, Markku (2023)

In conventional joint communications and sensing (JCAS) designs for multi-carrier multiple-input multiple-output (MIMO) systems, the dual-functional waveforms are often optimized for the whole frequency band, resulting in ...
Network-Aided Intelligent Traffic Steering in 6G O-RAN: A Multi-Layer Optimization Framework

Nguyen, Van-Dinh; Vu, Thang X.; Nguyen, Nhan Thanh; Luong, Nguyen Cong; Hoang, Dinh Thai; Nguyen, Dinh C.; Juntti, Markku; Nguyen, Diep N.; Chatzinotas, Symeon (2018)

To enable an intelligent, programmable and multi-vendor radio access network (RAN) for 6G networks, considerable efforts have been made in standardization and development of open RAN (O-RAN). So far, however, the applicability ...
