Abstract
A method and radio node (500) is used for realizing such as 256QAM high-order modulation in LTE. the first table configuration includes a first modulation and coding scheme MCS table and the first channel quality indicator CQI table in at least one of the table supporting the specific maximum modulation order. When the radio node (500) detects the potentially possible in radio communication when using higher maximum modulation order than a modulation order of the first table configuration the radio node (500) instructing the first UE (502) applying a second table configuration the second table arrangement comprises a second MCS table and second CQI table in at least one of the second table support higher modulation order. If desired at least one modulation order table upon application of the second configuration using the first table configuration is disposed in the second table of the table is maintained for at least one entry in at least one modulation order in first table configuration table as the backup. so as to realize higher data rate in a radio communication. the conventional MCS table and provided with handover signalling between the table with new MCS table with 256QAM entries.
A method and 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 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. A legacy MCS table and a new MCS table having entries with 256QAM are provided with the signalling to switch between these tables.
