UPLINK TRANSPORT FORMAT SELECTION

A method includes performing transport format combination selection so as to maximize transmission of higher priority data. The method operates, when scheduled and/or non-scheduled grants are taken into account for a transmission time interval, giving data of a given priority belonging to a scheduled MAC-d flow precedence over any lower priority data, whether belonging to a scheduled or a non-scheduled MAC-d flow; and giving data of a given priority belonging to a non-scheduled MAC-d flow precedence over any lower priority data, whether belonging to a scheduled or a non-scheduled MAC-d flow. In the method, where if the transmission contains any scheduled data, the size of a selected MAC-e protocol data unit is made not to exceed the total of all non-scheduled grants which are applicable for transmission in the transmission time interval; a maximum number of scheduled bits based on a serving grant, after adjustment for compressed frames, and a power offset; and the size of triggered scheduling information, if any. Also disclosed are corresponding apparatus and computer programs.
