Abstract: The disclosure describes methods and apparatuses for handover-related measurements and events for power adaptation. The disclosure provides for management of an eNodeB for improving reliability of incoming handovers to a cell provided by the eNodeB. At least one handover failure event for an incoming handover to a cell provided by the target eNodeB is detected. The eNodeB or central entity determines that the cell is providing an undesired coverage area based on the at least one handover failure event. In response to determining that the cell is providing an undesired coverage area, the transmit power for the cell may be adjusted to alter the undesired coverage area. A performance measurement based on the at least one handover failure event may be used to evaluate the undesired coverage area. The incoming handover failure events may include incoming too-early handovers, incoming too-late handovers, incoming wrong cell handovers, and incomplete incoming handovers.

Abstract: In a wireless communication system, a cell may perform a method for obtaining demand measurement data indicative of demand by one or more terminals for wireless service provided by the cell, and adapting a backhaul configuration of the cell based at least in part on the demand measurement data. The cell or network node may determine whether to adapt the backhaul configuration, based at least in part on the demand measurement data. The determining may include detecting a change in demand for use of the small cell by terminals that are not members of the small cell's closed subscriber group (CSG) that exceeds a threshold amount. The method may include changing an access mode of the small cell, in response to detecting the change in the demand. For example, changing the access mode may include changing from restricted access to open access, in response to detecting an increase in the demand.

Abstract: Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.

Abstract: Methods and apparatus are provided for configuring mobility or paging parameters of a femto node. A method includes determining capabilities of one or more neighboring access points based in part on signals received from the one or more neighboring access points. The method includes comparing the capabilities to one or more capabilities of the femto node to determine a mobility or paging parameter adjustment. The method includes adjusting one or more mobility or paging parameters based on the mobility or paging parameter adjustment.

Abstract: Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.

Abstract: Methods and apparatuses are provided that include adaptively configuring a rise-over-thermal (RoT) threshold at a base station to improve communications with one or more devices while mitigating interference to one or more other base stations. A potential device pathloss to the macrocell can be computed based on a measured pathloss thereto applied with a coverage area of the low power base station to emulate a worst-case device, one or more received measurement reports, and/or the like. The RoT threshold can be computed based at least in part on the pathloss and/or a maximum interference level at the macrocell. In addition, the RoT threshold can be adapted based on a reverse link attenuation level.

Abstract: Methods and apparatuses are provided that include adjusting rise-over-thermal (RoT) or noise rise (NR) threshold based on detecting interference from one or more devices. A device can communicate within close proximity of a femto node such that the device does not respond to power down commands from the femto node due to operating at a minimum transmit power. The device can cause the RoT or NR at the femto node to potentially rise over a threshold, however. Thus, the femto node can increase the RoT or NR threshold to allow the device to communicate with the femto node without impacting other devices communicating with the femto node. Out-of-cell interference from devices communicating with other base stations can be detected as well, and the RoT or NR threshold can be adjusted based thereon.

Abstract: Techniques are provided for mobile assisted reverse link interference management. For example, a method for providing mobile assisted reverse link (RL) interference management includes requesting at least one pilot strength measurement from a user device. The method may include receiving at least one macrocell pilot strength measurement or femtocell pilot or beacon strength measurement from the user device in response to the request. The method may include determining a data rate allocation for the user device based at least in part on the at least one macrocell pilot strength measurement or femtocell pilot or beacon strength measurement. The method may include transmitting the data rate allocation to the user device, thereby controlling RL interference caused by the user device to at least one non-serving cell.

Abstract: Low-power access points are used to identify traffic congestion zones in a network. The low-power access points collect metrics that are used identify high demand areas. The locations of the traffic congestion zones are then determined based on the locations of the low-power access points that identified high demand. In some embodiments, metrics are collected and processed in a distributed fashion at each femtocell. Each femtocell then outputs an indication of high demand in the area and/or takes action to address the high demand at an identified traffic congestion zone. Alternatively, the femtocells may collectively take action to address the high demand at one or more identified traffic congestion zones. In other embodiments, metrics may be collected from the femtocells at a central entity and processed to identifying any traffic congestion zones near the femtocells, whereby the central entity takes appropriate action to address the high demand.

Abstract: The disclosure is related to selecting an operating channel for a cellular network to reduce interference to a wireless local area network (WLAN) operated by a small cell comprising a WLAN access point and a cellular network modem. The small cell performs a channel scan of available channels, determines whether or not there is a clean channel to be the operating channel for the cellular network based on the channel scan, wherein a clean channel comprises a channel that interferes with the WLAN less than a WLAN interference threshold, and selects the clean channel as the operating channel for the cellular network based on the clean channel being available or turns off the cellular network based on no clean channel being available.

The method also includes causing a registration response to be sent to the wireless communication device based on the comparison.

Abstract: A method for enabling an active hand-in from a macro base station network to a femtocell network includes servicing an active hand-in of a mobile entity from a macro base station to a femtocell network, using a first femtocell of the femtocell network. The active hand-in includes a hard handoff of the mobile entity from the macro base station with soft handoff of the mobile entity enabled between the first femtocell and one or more neighboring femtocells in the femtocell network. The hard handoff with soft handoff enabled may be implemented using novel procedures implemented by one or more entities of a wireless communications network including the femtocells and macro base station.

Abstract: A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1xRTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1xRTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1xRTT and DO beacons for all access terminals entering the base station coverage.

Abstract: Transmissions of beacons by a set of access points (e.g., femtocells) are synchronized to facilitate discovery of the access points by an access terminal moving through the coverage areas of the access points. In some embodiments, periodic beacon transmissions are synchronized across all of the femtocells of a set of femtocells such that each femtocell transmits a beacon signal according to a similar pattern and at the same time. In some embodiments, an opportunistic beacon control scheme involves commencing beacon transmissions by at least one femtocell of a set of femtocells upon determining that an access terminal has communicated with one or more of the femtocells.
