摘要： A method for automatic hidden node detection that includes observing frame exchange sequences that conform to a MAC standard such as the IEEE 802.11 standard. The method includes detecting a hidden node upon receiving a response frame without previously receiving the frame causing the response. Similar conclusions may be drawn from longer frame sequences. When a hidden node has been detected with reasonable certainty, a hidden node report is sent to a hidden node manager. In one embodiment, the hidden node manager is centralized, and in another, the management function is performed in a distributed manner. Upon receiving a report, the hidden node manager automatically invokes hidden node avoidance measures by sending one or more action frames. In another embodiment, the hidden node manager turns on a hidden node mitigation method. In the case of the IEEE 802.11 standard, the hidden node manager turns on the IEEE 802.11 hidden node mitigation method based on RTS/CTS exchange.
摘要翻译：一种用于自动隐藏节点检测的方法，其包括观察符合诸如IEEE 802.11标准的MAC标准的帧交换序列。该方法包括在接收到响应帧时检测隐藏节点，而不事先接收到引起响应的帧。从较长的帧序列可以得出类似的结论。当合理确定的情况下检测到隐藏节点时，会将隐藏节点报告发送给隐藏节点管理器。在一个实施例中，隐藏节点管理器是集中式的，而另一个实施例中，分布式地执行管理功能。收到报告后，隐藏节点管理器通过发送一个或多个动作帧自动调用隐藏的节点回避措施。在另一个实施例中，隐藏节点管理器启用隐藏节点缓解方法。在IEEE 802.11标准的情况下，隐藏节点管理器基于RTS / CTS交换机来打开IEEE 802.11隐藏节点缓解方法。

摘要： An apparatus for inclusion and a method for operation in a station (STA) of a wireless network. The method includes received data from at least one remote station and determining a measure of the signal quality, e.g., a measure of the EVM from samples of the data received from the remote station(s). If the remote station(s) is/are access point(s), the station selects an access point for association according to criteria that include the measure of the EVM from the remote station. If the received data includes a request management message, the station responds to the request management message with a response management message that include a measure of the EVM of the received data corresponding to the request management message. Thus, the remote station receiving the response management message receives an indication of the quality of the link between the station and the remote station without the receiving remote station necessarily being EVM-capable.

摘要： An apparatus in a node of a wireless network for setting the data rate for sending data to a remote node, and a method for setting the data rate. The method includes receiving a packet from the remote node, determining a measure of signal quality for the received packet; and selecting the data rate for communicating to the remote node according to at least the determined signal quality. The measure of signal quality is a measure of the EVM of the received packet. One implementation conforms to one or more variants of the IEEE 802.11 standard that uses OFDM packets.

摘要： A method and apparatus for synchronizing a local clock value in a wireless receiver receiving a data unit containing synchronization information. The method includes receiving a first data unit containing synchronization information, extracting the synchronization information from the received first data unit, copying a local free-running clock at a known reference point in time relative to the time the first data unit was received to generate a local timestamp; and calculating an offset to the free-running clock using the extracted synchronization information and the local timestamp, the calculating in non real-time, such that the sum of the calculated offset and the value of the free-running clock provides a local clock value that is approximately synchronized in time. The apparatus implementing the method is part of a node of a wireless station, and provides a time synchronization function, typically at the MAC layer.

摘要： A MAC controller for a station in a wireless network, and a method for transmitting packets according to a wireless network MAC protocol. A MAC controller includes a packet scheduler connected to an interface for providing packets for transmission, and transmit hardware connected to a physical layer interface of the station to execute sub-sequences. The transmit hardware includes a buffer to receive from the scheduler and store a set of execution data, and also a signal path to the scheduling engine to provide an indication to the packet scheduler of the outcome of a sub-sequence. The transmit hardware is connected to a receiver to indicate the reception at the wireless station of a data unit that may be a response to a transmission of a sub-sequence.
