CityDeploy-Bench: Benchmarking Physics-Grounded Spatial Set Planning for Multi-Transmitter Network Deployment

Read the original on arXiv Machine Learning →

CityDeploy-Bench is a new benchmark that frames multi‑transmitter wireless network deployment as a physics‑grounded spatial set planning problem, verified by a unified ray‑tracing engine. It decouples utility representation from planning dynamics, allowing systematic comparison of direct scalar rewards, relational models, and higher‑order interaction structures across different planners. Experiments show that as physical coupling increases, deployment quality hinges on capturing collective transmitter interactions; stronger search alone cannot compensate for missing relational structure, highlighting the coordination nature of the problem.

Generalizable Multi-Task Learning for Wireless Networks Using Prompt Decision Transformers

arXiv:2606. 04328v1 Announce Type: cross Abstract: Future wireless networks demand rapid adaptation to highly heterogeneous environments and dynamic task configurations, necessitating a shift from conventional rule-based and optimization-driven radio resource management (RRM) toward artificial intelligence (AI)-driven RRM.

Multi-Modal Environment-Aware Beam Management for Massive MIMO: A Geometry-Driven Virtual Base Station Framework

The paper presents a geometry-driven framework for beam management in high-frequency massive MIMO systems. It constructs an offline virtual base station database using 3D LiDAR point clouds and location data to model dominant reflection paths, enabling a coarse channel reconstruction. A VBS-assisted orthogonal-pilot scheme and a dual-agent dueling double deep Q-network are then employed to refine beam estimates and perform coordinated beam selection, yielding improved training efficiency and performance over existing baselines.

MAPF-World: Action World Model for Multi-Agent Path Finding

MAPF-World introduces an autoregressive action world model for multi‑agent path finding that predicts short‑horizon local observations and neighboring agents’ action intentions, enabling decisions beyond immediate local views. The model incorporates a spatio‑agent positional encoding within Transformer architectures to enhance spatial awareness and agent semantics, fostering coordinated behaviors. Experiments on diverse maps, including a new automated map generator based on real‑world urban layouts, show that MAPF‑World outperforms existing learned solvers, achieving strong performance, robust zero‑shot generalization, and high success rates even at high agent densities.
