CONTROLLING ENERGY CONSUMPTION OF A WIRELESS NETWORK NODE

摘要

An arrangement for controlling energy consumption of a network node associated with a cell includes a terminal activity monitor configured to detect active terminals served by the cell. A transmission controller is connected to the terminal activity monitor and is configured to restrict transmission downlink in the cell during time periods when there are no active terminals served by the cell. During these time periods transmission is restricted to intermittent transmission of information assisting active terminals not served by the cell in finding the cell.
