Abstract(in English) | Cluster-wise distributed multi-user multiple-output multiple-input (MU-MIMO) is a promising solution for improving the transmission quality in the fifth generation (5G) advanced systems. When the clustering is introduced to reduce the huge computational complexity of large-scale MU-MIMO, the inter-cluster-interference (ICI) is produced, thereby reducing the sum capacity. Reasonable power allocation can effectively improve the system capacity while the total transmit power remains unchanged. Therefore, in order to make up for this loss, in this paper, the uplink/downlink power allocation is considered by taking into account the ICI to maximize the sum capacity. A new power allocation method is proposed, which is to maximize the sum capacity of the system under the cluster-wise total power constraint and cell-wise total power constraint, respectively, while satisfying the minimum user capacity requirement. Then, by computer simulation, the proposed method is compared to the user-wise equal power allocation method in terms of the achievable sum capacity. |
