Abstract  Abstract

The present invention relates to a network node such as a base station for a wireless communications system and to a method for supporting a change of a buffer estimation state of a user equipment from a passive to a proactive state. The method comprises receiving ( 410) information describing a buffer status of the user equipment and determining (420) whether to change the buffer estimation state of the user equipment to the proactive state based on the received information. The purpose is to achieve a more correct UE buffer estimation state and thus better accuracy for the buffer estimation.
