摘要

本文研究了不完全波束对准引导波束宽度调整的传感辅助毫米波网络的覆盖性能。提出了一种基于传感估计动态调整发射波束宽度的传感辅助自适应波束形成（SABF）方案，以实现波束形成增益与波束失调概率之间的良好平衡。为了指导网络部署中的波束宽度优化，考虑不完全感知估计导致的波束不对准，推导了基于随机几何的网络覆盖概率表达式。数值结果验证了解析表达式的准确性，证明了SABF方案在网络总体覆盖最大化方面的优越性。

Coverage Analysis and Beamwidth Adjustment for Sensing-Assisted mmWave Networks With Beam Misalignment

This letter studies the coverage performance of the sensing-assisted millimeter wave networks with imperfect beam alignment to guide beamwidth adjustment. A sensing-assisted adaptive beamforming (SABF) scheme is proposed where the transmitted beamwidth is dynamically adjusted based on sensing estimation to achieve a favorable tradeoff between beamforming gain and beam misalignment probability. To guide beamwidth optimization in network deployment, the stochastic geometry-based expressions for network coverage probability are derived, considering the beam misalignment caused by imperfect sensing estimation. Numerical results validate the accuracy of the analytical expressions, demonstrating the superiority of the SABF scheme that maximizes overall network coverage.
