Background & Motivation
Dynamic spectrum allocation in mobile networks, especially HetNets, faces growing complexity. Traditional methods (fixed assignments, centralized optimization) are limited. Auction-based mechanisms emerge as promising solutions to efficiently allocate limited spectrum by incentivizing users to reveal preferences. Most prior works focus on one-shot auctions or static bidder behavior, overlooking the dynamic nature of real-world wireless networks and the need for repeated auctions. Distributed settings require UEs to make two-stage decisions: BS selection and bid determination, introducing complex strategic considerations.
LLMs in Wireless Networks
Large Language Models (LLMs) offer remarkable abilities in context understanding, probabilistic reasoning, and strategy formulation. These capabilities make them promising for integration into UE decision-making, particularly in dynamic wireless environments with budget constraints and competitive bidding. Agentic-AI frameworks enable LLMs to act as autonomous agents for negotiation and strategic competition. Prior work has shown LLMs successfully participating in first-price auctions. This research extends LLM application to complex, realistic settings: repeated multi-channel spectrum auctions in HetNets where resources and budget dynamics evolve over time.
Proposed Framework
This work introduces a distributed, repeated multi-channel auction framework for HetNets. Each Base Station (BS) independently allocates spectrum, and User Equipments (UEs) autonomously decide association and bid values under budget constraints. This decentralized setup models realistic congestion where user demand exceeds available channels, making resource allocation a long-term economic decision. The framework investigates LLM-driven UEs that reason over past outcomes and adapt bidding strategies to maximize long-term utility within a heterogeneous HetNet environment. Contributions include a novel framework for LLM-guided bidding and association decisions in distributed HetNets, analysis of UE bidding strategies (myopic, greedy, LLM-based) on long-term utility and channel allocation, and extensive simulations demonstrating LLM-enabled UEs' adaptive, utility-enhancing behaviors.
Bidding Strategy Comparison
A comparative overview of different UE bidding strategies and their characteristics in repeated HetNet auctions.
| Feature | Myopic Truthful | Greedy Bayesian | LLM-based Strategic |
|---|---|---|---|
| Decision Scope | Single BS, current round | Multiple BSs, current round, expected utility | Multiple BSs, long-term utility, budget, competition |
| Bid Logic | True valuation | Calculates win probability and expected payment | Reasons over history, anticipates competition, adapts strategy |
| Budget Awareness | None | Implicit via utility calculation | Explicit (budget allocation across future rounds) |
| Adaptability | Low | Moderate (empirical CDF) | High (reasoning, learning, foresight) |
| Complexity | Low | Moderate | High (requires LLM) |

Higher Bid Precision for LLM UEs
LLM-enabled UEs achieved up to 50% higher bid precision, meaning more successful bids and fewer wasted resources. This precision stems from the LLM's ability to bid selectively, focusing on high-probability winning opportunities.

LLM vs. Myopic & Greedy Populations
Scenario: In a scenario with a myopic majority, a single LLM UE significantly outperformed both myopic and greedy UEs in average utility, especially over longer auction horizons. The LLM's strategic budget allocation across future rounds, unlike aggressive bidding without foresight, enabled it to exploit reduced bidding intensity in later rounds.
Results: LLM UEs consistently achieved higher channel access frequency and improved budget efficiency. This highlights the LLM's ability to adaptively manage budget and participation, translating into tangible resource advantages in repeated auction settings.
20%
Increased Channel Access Frequency
LLM-empowered UEs demonstrated 20% greater channel access frequency, especially in short-horizon simulations or under high-traffic conditions. This advantage comes from selective participation and conserved budget.
LLM Against a Greedy Population
Scenario: When competing against a majority of greedy UEs, the LLM's performance converged toward the top-performing greedy UEs, with utility margins reduced due to more volatile and competitive clearing prices. However, the LLM still maintained an advantage in channel access frequency.
Results: Even with reduced utility, the LLM-based UE secured significantly more sub-channel allocations in short-horizon simulations, thanks to its bid precision and reasoning. It conserves budget and avoids unnecessary entrance costs, maintaining ~10% improvement in spectrum access efficiency over longer horizons.
