Inband Full-duplex Self-backhauling in Ultra-dense Networks

Abstract

Traditionally, the backhauling of data in cellular networks has been handled by connecting the base station (BS) or access node (AN) to a core network via a physical cable. This ensures high data rates for the backhaul link, but requires the installing of cables that entails a high cost. This is an especially significant issue in the ultra-dense networks, where the number of ANs is too high for a physical backhaul link to be commercially feasible.
