A Study on Resource Allocation in Massive MIMO Heterogeneous Centralized Radio Access Network with Limited Backhaul/Fronthaul Capacity

摘要

In this paper, we study the resource allocation problem in massive MIMO heterogeneous centralized radio access networks (H-CRANs) with limited backhaul/fronthaul capacity. We formulate the joint frequency and power allocation optimization problem to maximize the downlink weighted sum rate of the system subject to per-remote radio head cluster (RRHC) power and backhaul/fronthaul capacity constraints. We propose iterative algorithms to solve the above formulated problem. After that, we provide numerical results to verify the effectiveness of the proposed algorithms through simulation under different parameters in mMIMO H-CRANs.
