Today we see that a major part of energy consumption in mobile networks comes from the radio base station sites and that the consumption is stable. We can also see that even in densely deployed networks, as in city centers, the network traffic load can fluctuate very much during the day,. The 5G NR standard has been designed based on the knowledge of the typical traffic activity in radio networks as well as the need to support sleep states in radio. The first deployments of NR are mainly non-standalone(NSA) deployments. This means that existing LTE base stations will still be used, and NR will be added for. We start by looking at the impact on user performance when introducing NR (Figure 6). We can notice that the LTE-only network is not sufficient to serve the. Ericsson has made a significant contribution to the standardization of the New Radio's energy saving features. Parts of this process were documented in our.
