Apparatus, and an associated method, for radio receiver circuitry operable in multi-modes to receive signals generated during operation of a multiple number of radio communication systems. The receiver circuitry is divided into receive chain portions which are selectably utilized depending upon which of the multiple number of the radio communication systems in which communications are to be effectuated. Selected combinations of the receive chain portions are formed, depending upon which of the modes in which the receiver circuitry is to be operable. Different combinations of the receive chain portions permit sharing of receive chain portions thereby to reduce the required number of circuit elements to form the multi-mode receiver circuitry. In one implementation, the radio receiver circuitry forms the receive portion of a dual-band, tri-mode mobile station operable in a selected one of three different cellular communication systems.
A multi-mode radio receiver operable to receive first receive signals generate during operation of a first radio communication system and to receive at least second receive signals generated during operation of at least a second radio communication system, said multi-mode radio receiver comprising:
In a method for operating a multi-mode radio receiver operable to receive first receive signals generated during operation of a first radio communication system and to receive at least second receive signals generated during operation of at least a second radio communication system, an improvement of a method for selectively acting upon the first receive signal and the at least second receive signal when received at the multi-mode radio receiver, said method comprising:
