MOBILE COMMUNICATIONS RADIO RECEIVER FOR MULTIPLE NETWORK OPERATION

摘要

A mobile communications radio receiver for multiple radio network operation includes an RF unit for generating 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. Further, the receiver includes a first receiving unit including a user data channel demodulator configured to demodulate a dedicated user data physical channel and a control channel demodulator configured to demodulate a common control data channel of the first radio network based on the first down-converted signal. Still further, the receiver includes a second receiving unit including a pilot channel demodulator configured to demodulate a pilot channel of the second radio network based on the second down-converted signal. A first data connection is configured to couple control data contained in the second down-converted signal to the control channel demodulator of the first receiving unit.

主权项

1. A method of demodulating user data in a mobile communications radio receiver, comprising:
generating a first down-converted signal from a radio signal received from a first radio network; generating a second down-converted signal from a radio signal received from a second radio network; demodulating in parallel a dedicated user data channel of the first radio network based on the first down-converted signal and a dedicated user data channel of the second radio network based on the second down-converted signal; and demodulating 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.
