Abstract
A method and radio node for enabling higher-order modulation in a radio communication with a first UE. A first table configuration comprises at least one of a first Modulation and Coding Scheme MCS table and a first Channel Quality Indicator CQI table which tables support a certain maximum modulation order. When the radio node detects that a modulation order higher than the maximum modulation order of the first table configuration is potentially possible to use in the radio communication the radio node instructs the first UE to apply a second table configuration which comprises at least one of a second MCS table and a second CQI table which second tables support the higher modulation order. At least one entry for at least one modulation order in the tables of the first table configuration is maintained in the tables of the second table configuration as a fall-back in case it is desirable to use the at least one modulation order of the first table configuration when the second table configuration is applied. Thereby a higher data rate can be achieved in the radio communication.
