Rate maximization in full‐duplex systems: Gains and complexity of employing adaptive power allocation in downlink and/or uplink

Abstract

The next generations of mobile communications should deal with a set of new use cases, leading to a higher demand for spectral efficiency. Full-duplex (FD) arises as a promising technology since it has the potential to double the system capacity without additional spectrum. However, FD networks are hindered by self-interference (SI) and co-channel interference caused by the reuse of frequency resources. Therefore, radio resource allocation (RRA) in FD networks by means of user pairing, frequency assignment, and power allocation are of utmost importance in order to improve spectral/energy efficiency and ensure quality of service (QoS). Although previous works investigated RRA to improve spectral

“…FD gain at the link-and network-level. At the higher layers, recent work focuses on characterizing the capacity region and rate gains, as well as developing resource allocation algorithms under both perfect [42], [43] and imperfect SIC [44]- [46], as well as various levels of available channel state information [47]. Similar problems are considered in FD multi-antenna/MIMO systems [35], [48]- [51].…”
