The invention relates to a method and an arrangement for reducing power
consumption of a receiver in a mobile communication network comprising a
sender transmitting packet data on a downlink channel to one or more
receivers over a radio interface. Inactive time instants and listening
time instants are defined according to provided rules. The receiver is
arranged to listen for information from the sender during the listening
time instants and to sleep during the inactive time instants. Thus, less
power will be consumed during the inactive time instants.
