ABSTRACT:
A method and system is disclosed for dynamically adapting operation of an auxiliary pilot according to reverse noise. An access terminal in a wireless communication system that includes a base station may operate in a first state in which the access terminal transmits a primary pilot signal on an air interface communication link to the base station, and also transmits an auxiliary pilot signal on the air interface communication link to the base station concurrently with transmission of the primary pilot signal. While operating in the first state, responsive at least to receiving a noise-level message from the base station indicating excessive reverse-link noise, the access terminal may transition to a second state in which it ceases to transmit the auxiliary pilot signal but continues to transmit the primary pilot signal.
