Patent ID: 8781408

Claim:
A method of operating a transceiver, the method comprising: in a first operating mode of the transceiver, receiving in a first frequency band while filtering a receive signal with a first filter having a first transition zone between a first pass band in the first frequency band and a first stop band in a second frequency band immediately adjacent to the first frequency band, the first transition zone extending further into the second frequency band than into the first frequency band; and in a second operating mode of the transceiver, transmitting in the second frequency band while filtering a transmit signal with a second filter having a second transition zone between a second pass band in the second frequency band and a second stop band in the first frequency band, the second transition zone extending further into the first frequency band than into the second frequency band, wherein: a boundary frequency defines a boundary between the first frequency band and the second frequency band; in the first operating mode, the first transition zone extends essentially from the boundary frequency into the second frequency band; and in the second operating mode, the second transition zone extends essentially from the boundary frequency into the first frequency band; receiving a channel assignment for communication, wherein the channel assignment includes a first channel having a first edge at the boundary frequency and a second channel having a second edge at the boundary frequency, the first channel being assigned for transmission, and the second channel being assigned for reception; and switching between the first and second operating modes based on the received channel assignment for communication.
