Mobile communications radio receiver for multiple network operation

A mobile communications radio receiver for multiple radio network operation, comprising:

• an RF unit configured to generate a first down-converted signal from a radio signal received from a first radio network and a second down-converted signal from a radio signal received from a second radio network;
• a first user data channel demodulator configured to demodulate a first dedicated user data physical channel contained in the first down-converted signal and a second user data channel demodulator configured to demodulate a second dedicated user data physical channel contained in the second down-converted signal;
• wherein the first and second user data channel demodulators are configured to demodulate the first and second user data physical channels in parallel;
• and
• a control channel demodulator configured to demodulate in a time-multiplex operation a common control channel of the first radio network based on the first down-converted signal and a common control channel of the second radio network based on the second down-converted signal.
