Dynamic resource allocation in mmWave unified access and backhaul network

In this paper, a mmWave unified access and back-haul (UAB) network is presented, where both radio access (RA) and backhaul (BH) share the same millimeter wave bands. Considering uniform resource allocation of RA and BH radio resource for all pico stations, which can well mitigate the interference among pico stations, the capacity of UAB is mainly influenced by the allocated resource ratio between RA and BH. Three dynamic resource allocation algorithms are proposed in this paper. The algorithms investigate maximization of network capacity and the fairness among stations, respectively. Results show that the proposed algorithms can well achieve a trade off between capacity and fairness guarantee. Compared to fixed resource allocation method, the system capacity can be improved up to 35% depending on the circumstance of traffic demands among pico stations.
