Device for processing signals in a mobile station
View Patent ↗A device for processing signals may be designed as a transmitting and receiving arrangement or exclusively as a receiving arrangement, and has a baseband component and a radiofrequency component. The interface between the baseband component and the radiofrequency component for the reception path is realized by an exclusively digital interface in the same way as the interface for the transmission path. The transmission of useful data—received useful data, useful data to be transmitted—is preferably effected via the digital interface completely separately from the transmission of the configuration data.
1. A receiving and transmitting arrangement for mobile radio, comprising:
a baseband component having an output buffer associated therewith, the baseband component configured to process a reception signal or a transmission signal, and comprising an input/output configured for digital data transmission;
a radiofrequency component configured to convert the reception signal into a baseband signal or convert a baseband signal into a transmission signal, and comprising an input/output configured for digital data transmission, and electrically coupled to the input/output of the baseband component for the digital transmission of useful data thereto or therefrom;
a first digital multiconductor connection coupled between the input/outputs of the baseband component and the radiofrequency component, respectively, and configured to transmit the received useful data from the radiofrequency component to the baseband component and the useful data to be transmitted from the baseband component to the radiofrequency component;
a second digital multiconductor connection coupled between the input/outputs of the baseband component and the radiofrequency component, respectively, and configured to transmit configuration data from the baseband component to the radio frequency component;
a synchronization line configured to provide a unidirectional data transmission from the baseband component to the radiofrequency component; and
a digital signal line configured to provide a unidirectional data transmission from the baseband component to the radiofrequency component,
wherein during a transmission operation, the radiofrequency component is activated via a signal on the digital signal line and all the configuration data required for the transmission are transmitted to the radiofrequency component via the second multiconductor connection, and wherein as soon as a predetermined quantity of data bits have been written to the output buffer of the baseband component, a start signal is communicated to the radiofrequency component via the synchronization line in order to request the data bits from the output buffer of the baseband component for transfer via the first multiconductor connection to the radiofrequency component for additional processing thereof.
2. The arrangement of claim 1 , the first digital multiconductor connection further comprising:
at least one data line configured for serial transmission of the received useful data;
a bit clock line configured for transmission of a clock signal, wherein a respective clock period thereof is assigned to a respective bit of the data line; and
a word clock line configured to indicate a beginning of communication of a sequence of bits on the data line.
3. The arrangement of claim 1 , the second digital multiconductor connection further comprising:
at least one data line configured for the serial transmission of the configuration data;
a bit clock line configured for the transmission of a clock signal, wherein a respective clock period thereof is assigned to a respective bit of the data line; and
a word clock line configured to indicate a beginning of communication of a sequence of bits on the data line.
4. The arrangement of claim 1 , wherein the inputs/outputs of the baseband component and the radiofrequency component are configured for a bidirectional data transmission.
5. The arrangement of claim 1 , wherein the first and second multiconductor connections are configured for a bidirectional signal transmission.
6. The arrangement of claim 2 , wherein the data line of the first multiconductor connection is bidirectional, and is additionally configured for the serial transmission of useful data to be transmitted, and the data line of the second multiconductor connection is bidirectional, and is additionally configured for the serial transmission of configuration data.
7. The arrangement of claim 2 , wherein the data line of the first digital multiconductor connection between the baseband component and the radiofrequency component is configured as a differential signal line.
8. The arrangement of claim 2 , wherein the baseband component and the radiofrequency component are both configured to employ a signal edge or signal pulse shaping protocol for the data line of the first digital multiconductor connection between the baseband component and the radiofrequency component.
9. The arrangement of claim 1 , wherein the baseband component and the radiofrequency component are configured together in a communication device configured for wireless transmission of signals with a base station.
