  • Publication number: 20110189986
    Abstract: 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.

  • Publication number: 20100315967
    Abstract: An access point is identified based on pilot signal information that appears on different frequencies. Here, a combination of one or more pilot PN spreading codes or one or more PN offsets on different frequencies are used to uniquely identify an access point. For example, upon receipt of a pilot measurement report, a network entity may uniquely identify an access point that transmitted the pilot signals based on at least one pilot PN spreading code or at least one PN offset and a plurality of frequencies identified by the report. Also, to facilitate acquiring this information, a network entity may request an access terminal to conduct an inter-frequency search for pilot signals. Also, an access terminal may maintain pilot information corresponding to access points in a network and use this information to autonomously conduct inter-frequency searches for pilot signals.

  • Publication number: 20100304745
    Abstract: A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.
