Claim:
1. A method of wireless communication in a multiple frequency band user equipment configured to operate in a single frequency band mode and a multiple frequency band mode, comprising: operating the multiple frequency band user equipment in the single frequency band mode with a first band or a multiple frequency band mode with the first band and a second band; routing uplink signals and downlink signals of the first band through a first duplexer and a bypass device when operating in the single frequency band mode and routing uplink signals and downlink signals of the first band and the second band through the first duplexer and a second duplexer, respectively, when operating in the multiple frequency band mode; bypassing a multiplexer through a bypass device while routing the uplink signals of the first band when operating in the single frequency band mode, and routing the uplink signals of the first band and the uplink signals of the second band through the multiplexer when operating in the multiple frequency band mode; and outputting, via the bypass device, a first downlink signal of the downlink signals of the first band, which bypasses the multiplexer, through the first duplexer when operating in the single frequency band mode and outputting, via the bypass device, a second downlink signal of the downlink signals of the first band through the first duplexer when operating in the multiple frequency band mode.
