A method in a communication device (100) and a communication device (100) for utilizing a first power mode and a second power mode of a digital interface (130, 330) between a first chip (110, 310) and a second chip (120, 320) are provided. When in the second power mode, the digital interface (130, 330) receives a data signal in a first time slot. The data signal comprises a control channel and a data channel. When the digital interface (130,330) enters the first power mode, the communication device (100) will determine a first point in time based on information comprised in the control channel. Furthermore, the communication device (100) determines a second point in time based on amount of data which is carried by the data channel at the first point in time. At the second point in time, the digital interface (130, 330) enters the second power mode and the data signal is transferred. |
