METHOD AND SYSTEM FOR USING TRANSMISSION HETERODYNE FOR IMPROVED CELL SEARCH AND COMMUNICATION OVER SEVERAL COMMUNICATION LINES IN MULTI-MODE DEVICE Russian patent published in 2012 - IPC H04B7/08 

FIELD: information technology.

SUBSTANCE: wireless device with several receivers has a transmitter, a transmitting heterodyne operably connected the transmitter, a receiving heterodyne operably connected to a first receiver and a second receiver, and a switching assembly, having a first state where the receiving heterodyne is connected to the first and second receivers, and a second state where the receiving heterodyne is disconnected from the second receiver, and the transmitting heterodyne is connected to the second receiver. The first receiver and second receiver of the wireless communication device can operate independently from each other when the switching assembly is in second state.
