Persistent Latent Memory for Multi-Hop LLM Agents: How a 6G Handover Paper Closes the Agent Cold-Start

Multi-hop LLM agent pipelines suffer from inefficiency because context is passed between agents as a simple text string, forcing the receiving agent to rebuild its state from scratch. This "cold start" problem can be solved using a method called Inductive Latent Context Persistence (ILCP), originally developed for 6G network handovers. The proposed architecture uses a β-variational autoencoder (β-VAE) to compress the sending agent's hidden state into a small latent payload. This payload is then transported and projected into the receiving agent's state space by a gated MLP, serving as a soft-prompt prefix to preserve context and avoid redundant computation.
