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.

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.
摘要翻译：多个节点之间的调度方法可以包括执行第一步骤序列，接着是第二步骤序列，每个序列包括Tx步骤，之后是Rx步骤。在Tx步骤期间，节点可以发送包含请求传输的REQ信号。在Rx步骤期间，另一节点可以接收请求信号，并且通过发送指示REQ信号的接受或偏转的确认信号来作出响应。 REQ信号包括单播部分和广播部分。在时隙的上行链路模式中，除了REQ信号的接受或偏转的指示之外，响应节点可以使用REQ信号的单播部分来发送补充信息。

摘要： 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 a 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 data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

摘要： Tones within a channel can be selected randomly and/or based on orthogonal tone selection. Random selection can include selecting tones randomly from a fixed set, which is referred to as channelized tone selection. Channelized tone selection can be chosen if a critical tone exists. Random selection can also include selecting resources randomly from the total number of resources available, which is referred to as non-channelized tone selection. Orthogonal tone selection can be chosen to mitigate the probability of receiver desensitization and/or to attempt to mitigate interference.

摘要： Multiple control indications are transmitted within timeslots defined for a slotted communication system. For example, a wireless node may transmit a control indication at a beginning of a timeslot and at an end of a timeslot. A control indication may comprise a resource utilization message that a node generates in an attempt reduce interference at the node that is caused by transmissions by neighboring nodes. A node also may synchronize to a received timeslot of another node based on the position of one or more control indications within the timeslot. Here, each control indication may include information that indicates the position of the control indication within the timeslot.

摘要： Providing for interference reduction and/or avoidance utilizing backhaul signaling between wireless access points (APs) of a wireless access network (AN) is described herein. By way of example, an interference avoidance request (IAR) can be issued by an AP to reduce signal interference on forward link (FL) and/or downlink (DL) transmissions by neighboring APs. The IAR can be routed via a backhaul network and/or over-the-air via access terminals (ATs) coupled with the AP or one or more interfering APs. Upon receiving the IAR, an interfering AP can determine reduced transmit power levels for FL and/or RL transmissions and respond to the IAR. The response can include reduced power levels and can be sent via the backhaul network or OTA. By employing the backhaul network in full or in part, interference avoidance can be conducted even for semi-planned or unplanned heterogeneous networks coupled by the backhaul.
