摘要： Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a 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. Transmit power may be defined based on channel quality. Transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes also may be controlled by inter-access node signaling.

摘要： Methods and apparatus for reverse link acknowledgement in a wireless local area network. A method includes receiving, at a first node, a data communication over a common channel, the data communication being decodable by other nodes. The method also includes determining transmission resources from the data communication, wherein the transmission resources are different for each node, and transmitting a response over the common channel using the determined transmission resources. An apparatus includes a transmitter configured to transmit to a plurality of nodes a data communication over the common channel, and a receiver configured to receive responses from the plurality of nodes, wherein each response was sent using different transmission resources determined from the data communication.

摘要： Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

摘要： Techniques are described for encoding an audio video stream that is transmitted over a network, for example a wireless or IP network, such that an entire frame of audio and an entire frame of video are transmitted simultaneously within a period required to render the audio video stream frames by an application in a receiver. Aspects of the techniques include receiving audio and video RTP streams and assigning an entire frame of RTP video data to communication channel packets that occupy the same period, or less, as the video frame rate. Also an entire frame of RTP audio data is assigned to communication channel packets that occupy the same period, or less, as the audio frame rate. The video and audio communication channel packets are transmitted simultaneously. Receiving and assigning RTP streams can be performed in a remote station, or a base station.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks at the same time. The mobile device registers a public ID with a first IP address over a first access network and also registers the same public ID with a different IP address over a second access network. Additional registrations and IP addresses may occur as well. Of particular benefit is that the different registrations are active during at least some concurrent period of time. This allows a user of the mobile device to have improved continuity of service, select preferred access methods, and receive different data services simultaneously.

摘要： Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.

摘要： Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.

摘要： Techniques for using wireless devices to implement sensor networks are described. For cognitive radio, a wireless device obtains measurements for a first system (e.g., a broadcast system) with which the wireless device is not in communication. The wireless device sends the measurements and associated location information and/or timestamps via a second system (e.g., a cellular system). A server receives measurements from a number of wireless devices and determines the coverage of the first system based on the measurements. For other applications, a wireless device obtains sensor information from at least one sensor at the wireless device and sends the sensor information and associated location information and/or timestamps via a wireless system. A server receives the sensor information and associated information from a number of wireless devices, aggregates the sensor information, and constructs a map. The wireless device may develop a user profile based on the sensor information and associated information.
