Claim of US Patent No. 9,294,038

1. A method, comprising:
determining that there is no transmission scheduled during a time period;
reducing a power amplifier bias during the inactive time period; and
restoring the power amplifier bias to nominal at the end of the inactive time period,
wherein the reducing the power amplifier bias comprises reducing the power amplifier bias to a threshold of a transistor of
the power amplifier.
