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.

A method for performing link adaptation of a radio link, the method comprising a transmission node:
- determining an estimation error of an estimated quality of the radio link;
- adapting a Modulation and/or Coding Scheme (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 a MCS based on the MCS input value as adapted.
A transmission node for performing link adaptation of a radio link, the transmission node comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the transmission node is operative to:
- determine an estimation error of an estimated quality of the radio link;
- adapt a Modulation and/or Coding Scheme (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;
- and
- select a MCS based on the MCS input value as adapted.
A non-transitory computer readable recording medium storing a computer program product for controlling link adaptation of a radio link, the computer program product comprising software instructions which, when run on processing circuitry of a transmission node, causes the transmission node to:
- determine an estimation error of an estimated quality of the radio link;
- adapt a Modulation and/or Coding Scheme (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;
- select a MCS based on the MCS input value as adapted.
