Message-based exchange of access point pilot signature indicators

An apparatus for communication, comprising:

• a receiver configured to receive a message from an access point at an access terminal, wherein the message includes at least one pilot signature indicator indicating one or more second pilot signatures associated with the access point that are not used for pilot signal scrambling by the access point, and to receive a pilot signal from the access point scrambled using a first pilot signature different from the one or more second pilot signatures indicated by the at least one pilot signature indicator;
• a pilot processor configured to generate a pilot report that includes respective different pilot signal strength indicators for the pilot signal and for the one or more second pilot signatures indicated by the at least one pilot signature indicator;
• a transmitter configured to transmit the pilot report to a second access point;
• and
• a transceiver configured to hand over to the access point, wherein a femto gateway identifies the access point based on information received from the second access point and information received from a femto management system, wherein the information received from the second access point is based on the pilot report, and wherein the information received from the femto management system comprises femto cell pilot signature allocations.
