1. Method of controlling transmission errors in a network comprising at least one transmitter, at least one receiver, a Radio Resource Management (RRM) unit for allocating transmission resource dedicated to said transmitter and/or receiver, and a FeedBacK (FBK) function comprising a transmitter FBK instance and a receiver FBK instance for managing transmission of feedback information which is transmitted by the receiver to the transmitter to indicate transmission errors, said method comprising the following steps:

  • a) said transmitter FBK instance transmits Protocol Data Units (PDUs) to said receiver FBK instance;

    b) said 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;

    c) said FBK function selects one feedback operational mode out of a predetermined list of feedback operational modes based on said determined transmission quality level, each one of said feedback operational modes defining a feedback resource allocation scheme for said transmitter FBK instance and said receiver FBK instance;

    d) said receiver FBK instance transmits to said transmitter FBK instance feedback information via a resource allocated based on said selected feedback operational mode.
