Abstract: The present disclosure presents methods and apparatuses for improved paging area identifier selection in femto nodes and other low power base stations. In some examples described in the present disclosure, a method is provided for selecting a paging area identifier at a low power base station, which includes determining whether a neighboring high power base station is detectable. Additionally, the method can include observing, where the neighboring high power base station is detectable, a broadcasted paging area identifier of the neighboring high power base station. Furthermore, example methods may include selecting a paging area identifier of the low power base station to be the broadcasted paging area identifier and transmitting the paging area identifier.

Abstract: In a multi-level power transmission scheme, an access point transmits at one power level, while repeatedly transmitting at a burst power level for short periods of time. For example, a femto cell may transmit a beacon with periodic high power bursts of short duration, while the femto cell transmit power also undergoes high power bursts aligned with the beacon bursts. In a network listen-based power control scheme, an access point listens for one or more parameters sent over-the-air by the network and then defines transmit power based on the received parameter(s). In some aspects, beacon transmit power may be set based on a defined outage radius parameter and the total received signal power on a channel. In some aspects, access point transmit power may be set based on a defined coverage parameter and the received energy associated with signals from access points of a certain type.

Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.

Abstract: Access terminals are provisioned to conduct intra-frequency, inter-frequency, and inter-RAT measurements and report physical layer identifiers of detected cells. The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier one subset at a time. In addition, the physical layer identifiers may be prioritized to improve the search procedure. Measurement report messages (including physical layer identifiers of the detected cells) are received at an access point as a result of the provisioning. A neighbor cell list for the femtocell is maintained based on the received measurement report messages and, optionally, other information. This other information may related to, for example, one or more of: physical layer identifier information received from access terminals that register with the access point, physical layer identifier information received via network listen operations, information regarding co-located cells, or physical layer identifier information received from a network entity.

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.

Abstract: Disclosed are systems and methods for regulating system reselections by idle-mode mobile devices. In one aspect, a femtocell may be configured to reduce frequency of its reselection beacon, which reduces probability that a fast moving mobile device will detect the reselection beacon and reselect to that femtocell. This aspect may also delay femtocell reselection for slow moving mobile devices. In another aspect, a macrocell may slow down system reselection by adjusting cell reselection parameters used by mobile devices to determine the time needed to evaluate cell reselection criteria. Yet in another aspect, a macrocell may instruct a collocated femtocell to decrease its effective coverage area to avoid premature reselection by fast moving mobile devices. Yet in another aspect, a femtocell may use power boosting techniques to increase its reselection radius.

Abstract: Information is communicated between access points to cause a recipient access point to invoke an action. In some aspects, a mapping is defined between: 1) sets of physical layer identifiers and/or associated time offsets; and 2) different types of information. The mapping information is provided to access points in a wireless communication system such that an access point can use this scheme to communicate specified types of information to another access point. Based on the mapping, an access point that receives a set of physical layer identifiers from another access point is able to determine the type of information being communicated. The recipient access point may then invoke a specific action based on the type of information that was communicated.

Abstract: Methods and apparatus are disclosed for interference mitigation of an open-access node. The method includes determining, at the open-access node, whether uplink interference from a mobile entity is above a threshold. The method includes adjusting a transmission power to trigger a hand-in of the mobile entity in response to determining the uplink interference is above the threshold. The method includes handing-in the mobile entity from a first cell in response to adjusting the transmission power. The method includes redirecting the mobile entity to a second cell different from the first cell.
