摘要：
本文研究使用模块化线性阵列（MLA）的协同波束赋形，该阵列由一对物理分离的均匀线性阵列（ULA）组成，并被视为子阵列。我们关注此类设置如何在无需大量天线的情况下，在6G网络中产生近场效应。与传统远场波束赋形不同，近场波束赋形能够在同一角度方向上为处于不同距离的多个用户同时提供数据服务，从而带来显著的复用增益。我们给出了详细分析，包括MLA的波束宽度和波束深度的解析表达式。研究结果表明，采用MLA方法，可以在去除ULA中约36%的天线的同时，实现相同水平的波束聚焦。
英文摘要：
This paper investigates coordinated beamforming using a modular linear array (MLA), composed of a pair of physically separated uniform linear arrays (ULAs), treated as sub-arrays. We focus on how such setups can give rise to near-field effects in 6G networks without requiring many antennas. Unlike conventional far-field beamforming, near-field beamforming enables simultaneous data service to multiple users at different distances in the same angular direction, offering significant multiplexing gains. We present a detailed analysis, including analytical expressions of the beamwidth and beamdepth for the MLA. Our findings reveal that using the MLA approach, we can remove approximately 36% of the antennas in the ULA while achieving the same level of beamfocusing.
