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： Interference management may involve the transmission of interference management messages by wireless nodes that are experiencing interference and appropriate responses by potential interferers that receive the interference management messages. Upon detection of interfering signals, a wireless node may determine whether the signals are from a synchronous interferer or an asynchronous interferer. Based on this determination, the wireless node may use different types of signals to manage the different types of interference. In some aspects, asynchronous interference management may involve backing-off in frequency and/or in time in response to interference signals. Asynchronous interference management may involve transmitting back-off beacons to clear potential interferers from a given carrier. Here, the transmission of beacons by a wireless node may be metered to facilitate fair sharing of communication resources.

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： Beacons may be grouped to facilitate neighbor discovery in a wireless network. For example, neighboring access devices such as IEEE 802.11 access points may cooperate to transmit beacons in a group. In this way, a wireless device seeking to discover the neighboring access devices may scan for the beacons for a shorter period of time. An indication may be provided to enable a wireless device to more efficiently scan the beacons. For example, the indication may indicate the channel the wireless device should scan to receive the next beacon that is to be transmitted. In addition, the indication may include information relating to the transmission time of the next beacon.
摘要翻译：信标可以被分组以便于无线网络中的邻居发现。例如，诸如IEEE 802.11接入点之类的相邻接入设备可以协作来传送组中的信标。以这种方式，寻求发现相邻接入设备的无线设备可以在更短的时间段内扫描信标。可以提供指示以使得无线设备能够更有效地扫描信标。例如，该指示可以指示无线设备应扫描的频道以接收将被发送的下一个信标。此外，该指示可以包括与下一个信标的发送时间有关的信息。
