This paper presents an integrated framework for beam scheduling optimization and initial access evaluation in 5G new radio (NR) non-terrestrial networks (NTN). A mixed integer linear program (MILP) is formulated to minimize the synchronization signal block (SSB) sweep period while enforcing full cell coverage, hardware...

Radio Resource Management (RRM) is a fundamental challenge in 6G wireless networks, particularly under dynamic user demands, inter-cell interference, and heterogeneous QoS constraints. Centralized optimization solutions are often infeasible in practice due to the lack of system-wide state information, dynamic condition...

Open radio access network (Open RAN) disaggregation across the distributed unit (DU), centralized unit (CU), and near-real-time radio intelligent controller (near-RT RIC) enables programmable, hierarchical radio access control. This architectural split allows independent optimization of short-term resource management a...

Distributed Radio Resource Management (RRM) is a fundamental challenge in 6G wireless networks, particularly under dynamic user demands, multilayer inter-cell interference, and heterogeneous QoS constraints. Centralized optimization solutions are often infeasible in practice due to signaling delay and the lack of syste...

Very low Earth orbit (VLEO) satellite constellations are a promising platform for uplink-dominated narrowband internet of things (NB-IoT) services. However, rapid topology variations and short satellite-gateway and satellite-user contact durations introduce significant routing challenges. This paper proposes a predicti...

A selective handover strategy is proposed where the path recomputation and VNF remapping are done only if there is a change in the previous routing path, which ensures that only critical handovers are carried out while discouraging unnecessary reconfigurations, which result in service discontinuity.
