摘要

即将发布的IEEE 802.11ax标准引入了空间复用和增强的空间分路复用，作为通过并行传输链路和空间流提高用户吞吐量的两种措施。相关研究表明，所提出的空间再利用概念并没有充分发挥空间再利用的潜力。该标准将空间分路复用限制为一个网络。本文研究了一种跨多个分散组织网络的空间分路复用概念，以消除同信道干扰。本文将空间复用的概念与空间复用的改进版本相结合，提出了相应的信道接入协议CSMA/SDMSR。基于IEEE 802.11ax的参考场景模拟表明，与标准CSMA/CA相比，CSMA/SDMSR系统性能提高高达108%，延迟降低。

Combined Spatial Division Multiplexing and Spatial Reuse across Decentral Wireless LANs

The upcoming IEEE 802.11ax standard introduces spatial reuse and enhanced spatial division multiplexing as two measures to improve user throughput by parallel transmitting links and spatial streams. Related work shows that the proposed spatial reuse concept does not fully utilize the spatial reuse potential. The standard limits spatial division multiplexing to one network. This paper investigates a spatial division multiplexing concept across multiple, decentrally organized networks to cancel co-channel interference. The paper combines the concept with an improved version of spatial reuse and introduces a corresponding channel access protocol, CSMA/SDMSR. An IEEE 802.11ax based simulation of reference scenarios demonstrates a CSMA/SDMSR system performance improvement up to 108 % and decreased latency compared to standard CSMA/CA.
