摘要： A method for providing repeater communication in a wireless repeater deployed in a multi-repeater environment includes inserting a message signal into the transmit signal of the repeater. The message signal may be a unique or quasi-unique low power spreading sequence uniquely identifying the repeater from other repeaters in the environment. The message signal may also contain information relating to the operational characteristics of the repeater. The message signal may be detected by another repeater or by an end-user wireless communication device.

摘要： A method for controlling gain in a wireless repeater implementing echo cancellation determines a signal-to-interference-noise-ratio (SINR) of the input and output signals of the repeater and adjusts the gain of the repeater to optimize an achievable data rate and a coverage area of the repeater. The repeater gain may be decreased to increase the data rate and increase the achievable SINR of the output signal while the coverage area is reduced. Alternately, the repeater gain may be increased to decrease the data rate and decrease the achievable SINR of the output signal while the coverage area is increased.

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： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

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.
摘要翻译： 本公开涉及能够同时访问不同类型的网络的移动通信设备。 移动设备通过第一接入网络注册具有第一IP地址的公共ID，并且在第二接入网络上向不同的IP地址注册相同的公共ID。 其他注册和IP地址也可能会发生。 特别有益的是，不同的注册在至少一些并发的时间段内是有效的。 这允许移动设备的用户具有改进的服务连续性，选择优选的访问方法以及同时接收不同的数据服务。
