Claim 3:
4. A mobile device comprising:
a baseband system configured to generate a sequence of symbols for transmission and a command for initiating sounding reference signal switching; and
a power amplifier module including a power amplifier and a switch configured to switch between a first antenna and a second antenna, the power amplifier module, in response to receiving the command, is configured in the following order to: reduce gain of the power amplifier to protect the power amplifier, switch between providing an output of the power amplifier to the first antenna to providing the output of the power amplifier to the second antenna, and increase the gain of the power amplifier prior to transmission of a sounding reference symbol on the second antenna without blank symbols inserted into the sequence of symbols for transmission during switching.
