Abstract

An improved mechanism for providing channel state feedback from a user equipment (UE) 800, to a base station 900 is provided, applying radio bearer specific channel state feedback reporting trigger criteria at the UE. In the UE it is initially determined (502) whether at least one channel state feedback reporting trigger criteria is valid or not, comprising the step of determining whether one or more channel state feedback reporting trigger is applied to one or more specific radio bearers. If this is the case, a channel state feedback report of a specified type is generated (510) and transmitted (511) to the base station. Such a mechanism provides for a more efficient control signaling of channel state feedback information between a base station and a UE.
