LTE-A UE Power Consumption for Carrier Aggregation Scenario

User equipment (UE) power consumption is a permanent concern for device manufacturers and users, which can be influenced by the network configuration. One of the main settings in LTE systems is carrier aggregation (CA). This paper compares real current measures over recently launched smartphone devices in CA and non-CA scenarios with the latest 3GPP releases. Results show that the most recent device had a reduction in power consumption of up to 39% and 44% for CA and non-CA scenarios, respectively. Allocating another carrier of 10 MHz increases only 13% in the newest model, while 61% in the previous one.
