Abstract
The invention provides a method and a radio node (500) for enabling higher-order modulation like 256QAM in LTE. 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 (500) 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 (500) instructs the first UE (502) to apply a second table configurationwhich 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. A legacy MCS table and a new MCS table having entries with 256QAM are provided with the signalling to switch between these tables.
