Abstract:
1. A method, comprising: receiving, by an interfering base station, a request, from an access terminal, to reserve transmission resources for the access terminal to allow communication with a serving base station; transmitting at least one authentication signal to the access terminal using a transmitter, the at least one authentication signal comprising a randomly generated authentication number that is channel-encoded to ensure that decoding of the authentication signal is substantially impossible below a predetermined signal quality threshold; receiving a response to the at least one authentication signal from the access terminal that indicates that the access terminal successfully recovered the at least one authentication signal from the transmitter; determining whether the access terminal is in a predefined proximity of the transmitter by determining the at least one transmitted authentication signal is received by the access terminal at or above the predetermined signal quality threshold based on a number of authentication signals successfully recovered by the access terminal over a predetermined period of time; selecting an amount of transmission resources to reserve as a function of the predetermined signal quality threshold; and reserving the selected amount of requested transmission resources upon determining that the access terminal is in the predefined proximity.
