Access point identification based on multiple pilot signature indicators

摘要

An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

主权项

1. A method of communication, comprising:
receiving a message for handover of an access terminal, wherein the message includes a plurality of cell identifiers each operable for scrambling a respective one of pilot signals from an access point, including at least one pilot signature that is not currently allocated for pilot scrambling use by any access points associated with an area of a wireless network that includes at least one access point identified by the plurality of cell identifiers; determining a cell identifier mapping for a plurality of access points, wherein the mapping maps different access points of the plurality of access points with different sets of at least two cell identifiers; and identifying one of the access points as a target for the handover based on the mapping and the cell identifiers included in the message.
