Abstract

Wireless point-to-point (PTP) FDD backhaul networks have great potential to be applied to metro cells. Unfortunately, their current spectrum utilization is very low because of static frequency allocation. We propose a new adaptive allocation algorithm, which dramatically improves the spectrum utilization and enables the networks to be practically applied to metro cells. Our algorithm adapts to dramatically changing metro-cell traffic, and eliminates co-channel interference and adjacent frequency interference between backhaul links. On a particular practical case study, simulations show that the new adaptive algorithm is able to enhance the network satisfaction regarding allocated bandwidths by over 161%, compared to the state of the art. It also improves the spectrum utilization by 33%.
