Zusammenfassung:	Methods and systems for fast sounding reference symbol (SRS) antenna port switching for FDD. A mobile device can include a baseband processor and a front end including a transmit power amplifier, a first transmit path, and a second transmit path. The front end can be configurable in a first mode to transmit via the first transmit path within a transmit band of a frequency division duplex band. The front end can be further configurable in a second mode to transmit via the second transmit path within a receive band of the frequency division duplex band.
