A method performed by a radio node of a cellular network, the radio node being operable to apply a first table configuration in radio communications with User Equipments, UEs, the first table configuration comprising at least one of a first Modulation and Coding Scheme, MCS, table and a first Channel Quality Indicator, CQI, table, wherein the at least one of the first MCS table and the first CQI table support a certain maximum modulation order, the method comprising: - detecting that a higher modulation order which is higher than the maximum modulation order of the first table configuration is potentially possible to use in a radio communication between the radio node and a first UE, and - instructing the first UE to apply a second table configuration in the radio communication, the second table configuration comprising at least one of a second MCS table and a second CQI table wherein the at least one of the second MCS table and the second CQI table support the higher modulation order, and wherein at least one entry for at least one modulation order in the at least one of the first MCS table and the first CQI table is maintained in the at least one of the second MCS table and the second CQI table as a fall-back in case it is desirable to use the at least one modulation order in the at least one of the first MCS table and the first CQI table when the second table configuration is applied, wherein the at least one modulation order in the at least one of the first MCS table and the first CQI table comprises a lowest modulation order of the first table configuration and wherein the first entry for the lowest modulation order in the first MCS table is maintained in the second MCS table as the fall-back, and an entry for the lowest coding rate of the lowest modulation order in the first CQI table is maintained in the second CQI table as the fall-back, and wherein selecting the fall-back for a transmission indicates use of the first table configuration for a next transmission. - detecting that a higher modulation order which is higher than the maximum modulation order of the first table configuration is potentially possible to use in a radio communication between the radio node and a first UE, and - instructing the first UE to apply a second table configuration in the radio communication, the second table configuration comprising at least one of a second MCS table and a second CQI table wherein the at least one of the second MCS table and the second CQI table support the higher modulation order, and wherein at least one entry for at least one modulation order in the at least one of the first MCS table and the first CQI table is maintained in the at least one of the second MCS table and the second CQI table as a fall-back in case it is desirable to use the at least one modulation order in the at least one of the first MCS table and the first CQI table when the second table configuration is applied, wherein the at least one modulation order in the at least one of the first MCS table and the first CQI table comprises a lowest modulation order of the first table configuration and wherein the first entry for the lowest modulation order in the first MCS table is maintained in the second MCS table as the fall-back, and an entry for the lowest coding rate of the lowest modulation order in the first CQI table is maintained in the second CQI table as the fall-back, and wherein selecting the fall-back for a transmission indicates use of the first table configuration for a next transmission.
