METHOD AND DEVICE OF ERROR CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a method and a device of error control that is efficient in case of high as well as low transmission error rates.

SOLUTION: A transmitter FBK instance transmits Protocol Data Units (PDUs) to a receiver FBK instance. A 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 defines 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.
