Radio link adaptation in communication systems

Abstract:

Method, preferably implemented in a transmission node (81, 91, 11), for performing link adaptation of a radio link (106, 108, C1), comprising: determining (72) an estimation error of an estimated quality of the radio link (106, 108, C1), adapting (74) a Modulation and/or Coding Scheme, referred to as MCS, decision input value, which is based on the estimated quality of the radio link, by increasing the MCS decision input value if the determined estimation error exceeds a predetermined threshold, selecting (75) a MCS based on the MCS input value as adapted.
