摘要： A method of scheduling among a plurality of nodes may include performing a first sequence of steps followed by a second sequence of steps, each sequence including a Tx step followed by a Rx step. During the Tx step, a node may send a REQ signal containing a request to transmit. During the Rx step, another node may receive the request signal, and respond by sending a confirmation signal indicating an acceptation or a declination of the REQ signal. The REQ signal includes a unicast portion and a broadcast portion. In an uplink mode of the slot, the responding nodes may use the unicast portion of the REQ signal to send supplemental information, in addition to the indication of the acceptation or the declination of the REQ signal.

摘要： A message exchange scheme for wireless communication employs a request, a grant, and a confirmation. In some implementations wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations a scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

摘要： A method of managing contention in a wireless network is described. The wireless network may include an access router and a plurality of access terminals connectable to the base station. The method may include designating a data slot as a downlink slot or an uplink slot, and sending a signal from the access router to the access terminals to indicate the designation of the data slot. The access router may determine whether the data slot should be designated as a downlink slot or an uplink slot by assessing information such QoS (quality of service) requirements contained in a REQ message received from one or more of the access terminals, and information regarding buffer level received from one or more of the access terminals.

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. The interferer may well receive interference management messages and determine that it is an asynchronous or synchronous interferer to an interfered node. The interferer then may determine to react consequently.
摘要翻译：干扰管理可能涉及由经受干扰的无线节点和接收干扰管理消息的潜在干扰源的适当响应的干扰管理消息的传输。在检测到干扰信号时，无线节点可以确定信号是来自同步干扰源还是异步干扰源。基于该确定，无线节点可以使用不同类型的信号来管理不同类型的干扰。在一些方面，异步干扰管理可以包括响应于干扰信号在频率上和/或时间上退出。异步干扰管理可能涉及发送回退信标以清除给定载波的潜在干扰源。这里，可以计量无线节点的信标传输，以便公平地共享通信资源。干扰源可以很好地接收干扰管理消息，并确定它是被干扰节点的异步或同步干扰。干扰源然后可能决定反应。

摘要： Apparatus and method for providing a relay between uplink and downlink nodes. The relay is provided by simultaneously communicating with the uplink and downlink nodes on a common channel. To increase throughput and efficiently utilize the available bandwith, the relay point (102B1) may be configured to communicate simultaenously with the access point (102A) and the terminal (104a). In order to communicate simultaenously, the radio resources must be allocated to the relay point (102B1) in a way that maintames orthogonality on both the uplink and downlink. The problem is that the relay point (102B1) allocates radio resources to the access terminal (104a) in the downlink transmit request in a time slot, but has no way to ensure that the access point (102A) does not allocate overlapping radio resources to it in the source timeslot. This problem may be solved by modifying the uplink transmit request to include a set of radio resources that are not being used by the relay on the downlink transmission. The resources can comprise frequency or spreading code assignments.
