Hi Frank, WUS and other 3GPP Release 15 features aren’t yet supported in the DT networks and to our knoweldge in most other Operator networks. Our focus is right now on completing the roll-out of key features like eDRX, while in parallel planning the introduction of new Rel. 14 features like New Category NB2. WUS and other important Rel. 15 features are of course already on our Roadmap, unfortunately we cannot give you a concrete date when those will be deployed in the our networks yet. Can’t eDRX to a certain extent address your power saving requirements for the time being? Best regards, Ronan
