Ue Current Consumption Over En-Dc Environments

User equipment (UE) power consumption is a permanent concern for device manufacturers and users, which is influenced by the network configuration. The battery performance of mobile terminals is one of the main key performance indicators (KPI) for the user experience since the beginning of the development of cellular mobile technologies. EUTRA-NR Dual Connectivity (EN-DC) is the solution for the first phase deployment of 5G architecture. This paper presents current consumption measurements on a high-end smartphone when configured with three different inter-band EN-DC scenarios. Each configuration adds an LTE component carrier (CC) of 20 MHz as the NR CC decreases in the same proportion, such that the channel bandwidth is maintained to 100 MHz. Measurement results expose lower consumption values when 1 LTE CC (20 MHz) + 1 NR CC (80 MHz) is performed. However, this scenario also produced the lowest throughput rate, showing a longer download time than the other two EN-DC scenarios.
