My research interest is based on mmWave IAB Full Duplex which is also my PhD project. The project aims at designing a New Radio (NR) integrated access and backhaul (IAB) network that is capable of simultaneously wirelessly backhaul the access traffic and wirelessly providing access to UEs utilizing the same time and frequency resources, thus scaling the spectrum efficiency with the number of IAB/user nodes.
