摘要

随着低功耗广域网（LPWAN

low-power wide area network）技术的快速发展和应用，越来越多的物联网终端需要接入网络。为应对海量物联网终端随机接入带来的挑战，提出了将大规模 MIMO 免授权随机接入（MGFRA

grant-free random access with massive MIMO）技术应用到LPWAN场景中。介绍了MGFRA技术并理论分析了 MGFRA 的性能，以验证其在极低信令开销的前提下大幅提升信道接入容量的性能优势。介绍了基于MGFRA的大容量LPWAN技术TurMass

。为展现TurMass

在实际应用中相较于现有LPWAN技术的优势，在典型LPWAN通信场景下对TurMass

和LoRa在信号覆盖、通信速率、网络容量、低功耗、低成本方面进行了对比。对比结果显示，与现有LPWAN技术LoRa相比，TurMass

在信号覆盖、通信速率、网络容量、低功耗、低成本方面具有突出的优势。

Abstract

With the rapid development of low power wide area network (LPWAN) technologies

more and more IoT terminals need to access the network.In order to deal with the challenge of massive random access

grant-free random access with massive MIMO (MGFRA) was proposed for LPWAN scenarios.The MGFRA was introduced and the performance of MGFRA to validate its performance advantage of greatly improving the channel access capacity with ext

reme low signaling overhead was theoretically analyzed.Further

TurMass

was introduced

which is a high-capacity LPWAN technology based on MGFRA.To demonstrate the advantages of TurMass

in practical applications

TurMass

and LoRa in signal coverage

communication rate

network capacity

low power consumption and low cost in typical LPWAN communication scenarios were compared.The comparison results show that TurMass

has outstanding advantages in signal coverage

communication rate

network capacity

low power consumption and low cost compared with LoRa.
