UE-to-UE Interference Measurement in Full Duplex Cellular Networks

With significant progress of full duplex technology, next generation wireless communication systems are moving toward application of full duplex enabled networks. The main challenges for the deployment of such networks is handling the additional interferences between nodes and devices. In an early deployment scenario where the base stations operate in full duplex mode while the user equipment remain in the half duplex mode, the mutual interference between the paired UEs of full duplex scheduling is a critical issue and needs to be well addressed in order to capitalize on the gain of a full duplex system. In this paper, we present design principles of a probing signal SUIM and propose a practical and reliable solution for UE-to-UE interference measurement in a full duplex network.
