Wireless communication systems with femto nodes

摘要

Systems and methods for performing a handoff of an access terminal from a macro node to a femto node are disclosed. In one embodiment, the femto node is configured to transmit a predetermined signal for determining signal quality and an identifier that uniquely identifies the femto node to the access terminal. The access terminal is configured to transmit the identifier to the macro node. The femto node is identified as a hand in target based on the transmitted identifier and the macro node is configured to hand in the access terminal to the femto node.
