    摘要： Resources are reserved for handover signaling. Handover reliability is thereby improved since the primary interference for handover signaling will be from the handover signaling of nearby cells (e.g., as opposed to data traffic). Given the relatively sparse nature of handover signaling, a significant reduction in interference may be achieved in a network employing this technique in comparison to conventional networks. In some implementations, a set of neighboring access points cooperate to determine which resources are reserved for handover signaling. In some implementations, resources for handover signaling are reserved on a network-wide basis or an access point cluster-wide basis.

    摘要： 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.
