- Abstract
- Recently, there is increasing interest in how to secure network capacity to support the exponential growth of mobile data traffic. Ultra-Dense-Network (UDN) is expected to solve the problem of network capacity by installing a smaller cell with high densification. But UDN has energy efficiency problems. since many cells consume a lot of energy. To solve this problem, small cell on/off is expected to be a key technology. However, small cell on/off has also challenge in guaranteed QoS of traffics. When a small cell is off, traffic of the cell is offloaded to the neighbor cell and the QoS problem occurs. In this paper, we solve the trade-off problem between QoS and energy efficiency by turning on/off small cells in consideration of QoS by deep learning which is a representative method to solve nonlinear problems. We find the optimized weighing factors of multiple criteria for small cell on/off such as traffic load, traffic QoS, number of UEs and path loss based on learning approach.
