Full duplex enabled next generation mmwave wifi network

Abstract

. The full-duplex technology with the same frequency and the same time has developed rapidly in the wireless communication field. Compared with the traditional half-duplex technology, full-duplex technology can obtain the double spectral efficiency and throughput. However, in low-frequency asymmetric full-duplex communication, AP has full-duplex, and STA only has half duplex. And the interference between STAs results that we still cannot reach the theoretical multiple throughput. In this paper, we use the feature of directional propagation of mm wave to eliminate the interference between STAs in asymmetric full-duplex communication, and the full-duplex is applied to the WIFI high-frequency field for the first time. This paper introduces the BI frame of MAC architecture of IEEE 802.11 ay protocol in mmWave WIFI network, and designs the SP period of BI frame. So in SP period, the AP has full-duplex function and STAs still are half-duplex. We use Matlab to simulate, and get the theoretical multiple throughput.
