The method includes providing a stream of data to be transmitted, and processing the data by means of channel coding with a time-varying code rate, thereby generating a stream of channel coded data. The method further includes forming succeeding transmission time intervals and distributing the channel coded data on the transmission time intervals, and adjusting a transmission power of the signal to be transmitted by timely positioning a transmission power slope between two succeeding transmission time intervals so that the transmission power slope is contained completely within one transmission time interval of the two transmission time intervals, wherein the one transmission time interval comprises a lower nominal code rate or a lower nominal transmission power than the other one of the two transmission time intervals.
