Enhancing SDVN Performance via Policy-Driven Lightweight Control-Plane Resizing Strategies

Software-defined vehicular networks (SDVNs) under high mobility and fluctuating traffic demand offer programmable, centralized control for latency-sensitive intelligent transportation systems. However, data-plane Quality of Service (QoS) is often degraded by control-plane overload due to frequent handovers and dense ve...

Outage Analysis of RSMA-Enabled Terrestrial Users Under Co-Channel Interference from HAPS

The coexistence of terrestrial networks (TNs) with high-altitude platform station (HAPS)-based non-terrestrial networks (NTNs) is a promising approach for extending 6G connectivity, but the resulting cross-network interference can significantly affect TN reliability. This paper investigates an rate-splitting multiple a...

Performance Analysis of HAPS-Assisted Downlink RSMA under Orthogonal and Full Frequency Reuse

Numerical results show that the optimal common stream power allocation depends on the transmit power, while inter-beam interference under frequency reuse introduces an outage floor absent under orthogonal allocation, providing practical design insights for HAPS-RSMA systems.
