(54)	Technique for automatic gain control in a multi-carrier communication system

(57) A technique for performing Automatic Gain Control (AGC) in a multi-carrier communication system in which transmission gaps are scheduled on a serving carrier to enable temporary tuning to another carrier by a served device is described. A method embodiment of this technique comprises: performing a first AGC procedure in relation to a first signal received on a first carrier during a first transmission gap; determining an AGC configuration for a second procedure based on at least one of channel conditions in relation to the first carrier and a lapsed time since the first transmission gap; and determining if the second AGC procedure can be skipped.
