Patent ID: 8718052

Claim:
A method for switching signal paths in a circuit arrangement for processing and/or influencing signals in radio communication, the method which comprises: switching at least the transmission paths of the relevant circuit arrangement to active state or inactive state for radio communication based on a presence of a transmission signal from a terminal that is operated with said circuit arrangement and which operates in one or more of a plurality of frequency bands that are supported by the circuit arrangement; periodically checking in succession the transmission paths which are deactivated in a basic state of the circuit arrangement and which are configured to transmit transmission signals in different frequency bands, for the presence of a transmission signal from the respective terminal operated with the circuit arrangement; if a transmission signal is found to be present, activating only the transmission path for the frequency band of the transmission signal and continuing to check only the said transmission path for the presence of a transmission signal; and deactivating the relevant transmission path, which is constantly checked for the presence of the transmission signal, when the transmission signal is absent; and subsequently to deactivating the relevant transmission path, continuing a periodic check on all transmission paths for the presence of a transmission signal.
