IEEE 802.11ay enabled integrated mmWave radar detection and wireless communications

Abstract

Integrated sensing and communication (ISAC) under the same frequency band and hardware has emerged as a key technology in future wireless networks. Meanwhile, the harmonious coexistence between detection and communication modules has also attracted tremendous research interest in both academia and industry, currently. In this work, we propose a novel Integrated detection and communication (IDAC) scheme in the promising IEEE 802.11ay enabled millimeter wave (mmWave) networks. Particularly, we first introduce a mixing personal basic service set control point or access point (PCP/AP) architecture to support the IDAC function. Thereafter, we embed the radar detection into the IEEE 802.11ay beamforming training (BFT) period by utilizing its directional scanning feature. Furthermore, a BFT and energy allocation strategy is derived to balance the performance between detection and communication. Numerical results demonstrate the effectiveness of the proposed scheme.
