ENERGY EFFICIENT OPERATION OF RADIO NETWORK NODES AND WIRELESS COMMUNICATION DEVICES IN NB-IOT

摘要

A radio network node may operate in a normal or restricted operating state. In the restricted operating state, the radio network node may have just enough activity to enable UEs to detect the cell. The radio access node may transition to the normal operating state in response to messaging from a wireless communication device, such as reception of a random access preamble.
