Abstract
Exemplary embodiments are directed to reverse-link signaling via modification of an impedance on the receiver as detected by a transmitter. A method may include receiving a signal from a transmitter at a receiver unit. The method may further include adjusting an impedance detectable by the transmitter by modifying a load coupled with the receiver unit.
