摘要： Systems and methodologies are described that facilitate establishing synchronization and/or mitigating interference with a time division duplexing (TDD) access point base station in a wireless communication environment. For example, a TDD configuration can be selected for the access point base station based upon received information to control interference. By way of another example, the access point base station can be synchronized with a disparate base station based upon the received information. Moreover, the received information can relate to the disparate base station, a served user equipment (UE) (e.g., served by the access point base station, . . . ), and/or a non-served UE (e.g., served by a base station other than the access point base station, . . . ). For example, the served UE can transmit a measurement related to the disparate base station to the access point base station.

摘要： Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.

摘要： A set of nodes may communicate in a manner that is asynchronous with respect to the communication between other sets of nodes. To facilitate reservations of resources by different nodes, a node may transmit a message that requests neighboring nodes to limit their interfering transmissions on a given resource and then transmit another message to inform the neighboring nodes that the node is no longer using the resource. To address problems that may be caused by concurrent asynchronous transmissions by different nodes, a messaging scheme may be used to enable a first node to acquire control information transmitted by asynchronous neighboring nodes while the first node was transmitting, and was thereby unable to receive control messages.

摘要： Systems and methodologies are described that facilitate providing physical cell identifier (PCI) assignment. Neighboring access point parameters can be collected and transmitted to a PCI assigning component, which can generate a PCI based on the parameters as well as other local parameters. The neighboring access point parameters can be received by evaluating signals transmitted by the neighboring access points, from a UE communicating with the neighboring access points, over a backhaul link, etc. The parameters can include signal strength, identification, and/or the like. In addition, prioritized lists of PCIs can be provided to an access point, which can utilize the neighborhood parameters to select an optimal PCI from the list.

摘要： Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over-the-air packet to indicate a termination point for the packet. Also, different mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic. Thus, an access terminal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic. Furthermore, messages associated with one protocol may be carried over another protocol to reduce complexity in the system.
