Abstract: Aspects describe communications environments in which femtocell capability is provided to devices within the communications network. A non-femto-enabled device and/or a femto-enabled device can communicate with a femto-enabled device in the same geographical area for femto-enabled peer-to-peer communication. Two non-femto-enabled devices can be provided femto functionality through utilization of a femto-enabled device, which operates as a hub between the two devices. Other aspects relate to enhanced position determination, adaptive coverage enhancement, local mobile networks, open access femtocells without a backhaul, and local broadcast of media though utilization of femto-enabled devices.

Abstract: Interference that occurs during wireless communication may be managed by determination of a selected transmit waveform exhibiting a preferred channel quality. A method, apparatus and medium of communication determine a transmit waveform from among a plurality of allocated waveforms of an unplanned access point to an associated access terminal. The transmit waveform exhibiting a highest channel quality with an associated access terminal over others of the plurality of allocated waveforms is determined. Signals are transmitted according to the transmit waveform from the unplanned access point to the associated access terminal.

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: 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.

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.

Abstract: Methods and apparatuses are provided that include deploying a femto node in a wireless network. The femto node can measure received signal quality upon initialization in a wireless network and/or according to a timing. The femto node can determine whether to communicate in the wireless network based on comparing the received signal quality to a threshold signal quality. The timing can be determined based on various factors to ensure fairness among femto nodes initializing in the wireless network. A centralized entity can be used to determine the timing and/or whether a femto node should communicate.

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 through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques.

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: Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.

Abstract: Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

Abstract: In some aspects, restricted access nodes are assigned to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspects, an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspects, an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspects, access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.

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.

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: Described herein are techniques for reducing interference to non-cellular communications on an unlicensed band by a network entity sending/receiving cellular communications on the unlicensed band. For example, the technique may involve accessing a list of channels for cellular communication on the unlicensed band, the list having the channels in an order of priority for reducing interference to non-cellular communication on the unlicensed band. The technique may involve determining an interference criteria for a received signal, the interference criteria being based at in part on at least one of a received signal strength indicator (RSSI) or a duty cycle of the received signal. The technique may involve going through, in the order of priority, each channel in the list to identify a first channel that satisfies the interference criteria.
