In this article, the design of a highly efficient and flexibly deployable wireless backhaul is addressed as a promising alternative to the typical wired solutions. To this end, two novel approaches are presented, one proposing relay transmissions with multiple antennas based on the notion of data splitting and a second one addressing resource allocation with distributed scheduling. A proof-of-concept hardware prototype was developed as a means to demonstrate the efficiency of the proposed concepts and algorithms and investigate the performance benefits and complexity requirements.
