摘要： Disclosed are methods, apparatus, computer readable media and other implementations, including a method for communicating network information. The method includes transmitting a request message from a mobile device to an access point, and receiving, at the mobile device, a reply message transmitted from the access point in response to receiving the request message, the reply message including data representative of a transmitted signal power level at the access point of the reply message. The method further includes determining, based on the received reply message including the data representative of the transmitted signal power level at the access point, a received signal power level at the mobile device of the reply message, and a round trip time from a first time instance when the request message was transmitted from the mobile device to a second time instance when the reply message was received at the mobile device.

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： Systems and methods are described that facilitate the determination and request of resources a node may wish to reserve. The resources include a plurality of carriers that are shared with other nodes. In an approach, the node determines a condition related to the plurality of carriers; creates an ordering of the plurality of resources; and transmits a resource utilization message (RUM) for one or more of the plurality of resources based on the ordering and the condition.

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 methods are described that facilitate evaluating conditions of nodes (e.g., access points, access points, access terminals, etc.) in a wireless communication environment having a plurality of carriers to determine a level of disadvantage for a given node relative to other nodes. The node may transmit a resource utilization message (RUM) that represents the level of disadvantage for the node and request other interference nodes to back off on one or more carriers. This would allow frequency reuse if nodes vary the power of transmission for particular carriers, in conjunction with neighboring nodes.
