Patent ID: 7711056

Claim:
A method for transmission of monitoring and payload data in a transmitting and receiving arrangement for a wirefree communications system, comprising: providing a device which processes baseband and is integrated on a first semiconductor chip for processing digital signals to form a baseband signal, and vice versa, providing a device which processes radio frequency and is integrated on a second semiconductor chip for conversion of the baseband signal to a radio-frequency signal, and vice versa, providing a link between the baseband device and the radio frequency device, transmitting monitoring data and payload data between the two semiconductor chips in the form of data packets via at least one channel of the link, wherein the at least one channel comprises one or more physical lines between the device which processes baseband and the device which processes radio frequency, for bit-by-bit or symbol-by-symbol data transmission, and wherein the data packets in each case comprise a first part and a second part, and wherein a start of the first part comprises a start bit, which indicates the start of a data packet to the baseband device or to the radio-frequency device, and the first part further comprises packet indicator information, consisting of a single bit, which indicates whether the data packet is being used to transmit monitoring or payload data, providing a periodic clock signal in the device which processes radio frequency from a sequence of clock pulses, transmitting the periodic clock signal via a further channel of the link to the device which processes baseband, wherein the periodic clock signal comprises a reduced clock signal that is transmitted to the device which processes baseband, in which only every n-th clock pulse of the sequence of clock pulses which is produced in the device which processes radio frequency is transmitted to the device which processes baseband, wherein n is an integer greater than zero, and providing the device which processes baseband with an indication as to whether the reduced clock signal is being transmitted to the device which processes baseband, via a status indicator provided from the device which transmits radio frequency to the device which transmits baseband via at least one channel of the link.
