Abstract
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.

A method for transmitting a signal in a mobile communication system, comprising:
- providing a stream of data to be transmitted;
- processing the data by channel coding with a time-varying code rate, thereby generating a stream of channel coded data;
- 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,
- wherein one of the two succeeding transmission time intervals comprises a first nominal code rate or a first nominal transmission power and the other one of the two succeeding transmission time intervals comprises a second nominal code rate or a second nominal transmission power, respectively, and wherein the second nominal code rate or the second nominal transmission power is greater than the first nominal code rate or the first nominal transmission power, respectively, the method further comprising:
- adjusting the transmission power slope if the difference between the first nominal code rate and the second nominal code rate or between the first nominal transmission power and the second nominal transmission power is above a predetermined threshold.
