ABSTRACT:
A method and system is disclosed for triggered operation of a variable auxiliary pilot based on RF conditions. An access terminal operating in a wireless communication system may switch on its auxiliary pilot in response to receiving a first threshold number of power-up commands from a serving base station. Responsive to thereafter receiving each of a second threshold number of power-up commands, the access terminal may increment the gain of its auxiliary pilot while holding the gain of its primary pilot fixed. The access terminal thereby sets its auxiliary pilot gain independently of its primary pilot gain for a select number of power-control commands. The access terminal may respond to subsequent power-control commands by responsively adjusting the gain of it primary pilot, and linking the gain of its auxiliary pilot to the gain of its primary pilot. Upon receiving a third threshold number of power-down commands, the access terminal may switch off its auxiliary pilot.
