Abstract
There is disclosed a method and a device of controlling transmission errors in a network comprising at least one transmitter, at least one receiver and a Radio Resource Management (RRM) unit for allocating transmission resource dedicated to the transmitter and/or the receiver. A FeedBacK (FBK) function is introduced to manage transmission of feedback information which is transmitted by the receiver to the transmitter to indicate transmission errors. The FBK function comprises a transmitter FBK instance and a receiver FBK instance. At first, the transmitter FBK instance transmits Protocol Data Units (PDUs) to the receiver FBK instance. The FBK function monitors transmission errors on the receiver FBK instance side and/or on the transmitter FBK instance side to determine a transmission quality level out of a set of given transmission quality levels. The FBK function selects one feedback operational mode out of a predetermined list of feedback operational modes based on the determined transmission quality level, each one of feedback operational modes defining a feedback resource allocation scheme for the transmitter FBK instance and the receiver FBK instance. The receiver FBK instance transmits to the transmitter FBK instance feedback information via a resource allocated based on the selected feedback operational mode.
