Trend analysis to increase the downlink throughput in a mobile system

摘要

A method for selecting a modulation and coding scheme including schemes comprising a plurality of coding schemes and at least one modulation scheme, which scheme is to be applied to a downlink connection in a cellular radio system, the method comprising: selecting from a table a MCS value on the basis of at least one measured radio link parameter; monitoring the at least one parameter, determining a trend of change of the at least one parameter, and modifying at least one MCS value in the table taking into account the determined trend. By modifying MCS values in an existing MCS table, the table can be adapted to the existing radio conditions. Thus, the downlink throughput is increased.
