The IEEE Task Group ay (TGay) has recently defined new physical and medium access control specifications to design the next generation wireless standard in the 60 GHz band, the so-called IEEE 802.11ay. Build upon its 802.11ad predecessor, IEEE 802.11ay aims to offer unprecedented performance (100 Gbps throughput, ultra-low latency) by introducing various technological advancements such as multiple-input and multiple-output (MIMO) communication, channel bonding/aggregation, and new beamforming techniques. Such performance paves the way to new emerging wireless applications such as millimeter-wave distribution networks, data center interrack connectivity, mobile offloading, augmented reality (AR)/virtual reality (VR), and 8K video streaming. Studying and analyzing these new use-cases is of paramount importance and demands high fidelity network-level simulator due to the scarcity/costs of real IEEE 802.11ay test-beds. In this paper,we present our implementation of the IEEE 802.11ay standard in the network simulator ns-3. Our implementation captures the specifics of IEEE 802.11ay operations such as 11ay frame structure, channel bonding, new beamforming training procedures, quasi-deterministic MIMO channel support, and Single-User (SU)-MIMO (SU-MIMO)/ Multi-User (MU)-MIMO (MU-MIMO) beamforming training. We validate and demonstrate by simulations the performance of the aforementioned techniques. The code for our simulation model is publicly available.
