Power allocation for in-band full-duplex self-backhauling [PDF]

2017 40th International Conference on Telecommunications and Signal Processing (TSP), 2017
Ultra-dense cellular networks are emerging as one key characteristic of 5G wireless networks. In this context, frequency reuse is a fundamental technology enabler for efficient utilization of limited spectrum resources. In this paper, we investigate the in-band Full-Duplex (FD) self-backhauling architecture, in which Base Stations (BSs) operate on the ...
