    摘要： Mobile user equipment (MUE) can be enabled to search for and camp on a preferred node, such as a home base node (HBN), in a battery-efficient manner even when currently camped on another node, such as a macro base node (MBN). When the MBN provides good channel quality, slow rate background intra- and inter-frequency searches can discover the preferred HBN that would otherwise not be discovered or would consume excessive power with continual searching. When channel quality is fair, slow rate background inter-frequency searches can result in timely switching to the preferred HBN. Location hints that indicate proximity of the preferred HBN can be used to trigger slow rate background searches. Neighboring cell searching of neighbor cell listing (NCL) when in channel quality is fair or poor are maintained to prepare for call reselections to available node.

    摘要： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

    摘要： An access point generates beacons at different power levels at different times to provide an acceptable tradeoff between coverage area associated with the beacons and outage experienced at nearby access terminals. For example, a femto access point may transmit beacons at a relatively low power for a relatively long period of time to reduce interference at nearby access terminals that are being served by a macro access point. The femto access point may then transmit beacons at a relatively high power for a relatively short period of time to enable nearby access terminals to receive the beacons. Also, a given transmit chain may be used to provide frequency hopping of high and low power beacons.

    摘要： Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.

    摘要： Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.
