Abstract
A node (5) for use in a cellular network (4) to control the transmission of data from a radio base station (3) in the cellular network to a mobile terminal (1), is proposed, said node (5) comprising memory (7) for storing a channel quality value reported by the mobile terminal, and acknowledgement messages received from the mobile terminal, and calculating means (9) for calculating an adjustment value for the channel quality value based on the acknowledgement messages. The calculating means (9) is arranged to calculate said adjustment value for the perceived channel quality value taking into account at least two responses related to at least two blocks, and calculate said adjusted value using the adjustment value. The evaluation may be based on consecutive acknowledgement messages or on statistics derived from a plurality of messages.
