摘要
This paper analyses user equipment measurements and network performance indicators to address uplink power allocation problem in multi-vendor heterogeneous networks. First, the selection of optimal open-loop power control strategy is studied by comparing equal Power Spectral Density (PSD) strategy with Min-Median maximization strategy. Later, the best open-loop strategy is compared to closed-loop power control performance. The analysis show that the Min-Median scheme outperforms the equal PSD by balancing the performance and improving the uplink throughput by 30 %. In live deployment, uplink transmit power levels were observed to be higher than expected based on the open-loop power control strategy. Therefore, the equal PSD criterion is not able to balance the interference conditions between the network layers. Moreover, closed-loop power control strategy further improves the uplink throughput by 61 % if compared with the optimal OLPC configuration.
