Intent-Driven Communication (IDC) is emerging as a key paradigm for autonomous 6G networks, where AI and Large Language Models (LLMs) translate high-level user intents into actionable network policies. Meanwhile, Reconfigurable Intelligent Surfaces (RIS) and dynamic spectrum leasing are becoming essential for improving coverage and capacity in resource-constrained environments. This paper extends the IDC framework by integrating RIS and spectrum leasing into AIassisted intent translation, policy mapping, and orchestration. A leasing-aware architecture is presented, and a Lyapunov-based Decision Support Framework is implemented as an illustrative mechanism for intelligent resource acquisition under timevarying prices and availability. Simulation results validate that the DSF achieves cost-efficient, delay-aware orchestration while exhibiting the expected Lyapunov stability properties. These findings highlight the feasibility of combining IDC with intelligent resource leasing in future 6G systems.
