The relay is configured to simultaneously communicate with the uplink and downlink nodes on a common channel. For simultaneous communication, radio resources may be allocated to the relay to maintain orthogonality on both the uplink and downlink.

摘要： 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 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.
摘要翻译：无线媒体访问控制支持异步通信和重叠传输。这里，无线节点可以基于从相邻节点接收到的控制消息来确定是否请求或调度传输。在一些实施方式中，调度的传输可以被划分成若干段，使得发射节点可以在段之间接收和发送控制消息。在一些实施方式中，在调度的传输周期之后定义监视周期，以使得发送节点获取否则可能在调度的传输周期期间已经发送的控制信息。在一些实施方式中，数据和控制信息通过不同的频分多路复用通道传输，以实现数据和控制信息的并发传输。

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/或时间上进行退出。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。

摘要： Apparatus and method for supporting wireless downlink and uplink connections. In the downlink direction, an apparatus receives from the downlink node a request to communicate using an allocation of radio resources specified by the downlink node, and transmits to the downlink node a grant to communicate using at least a portion of the specified allocation of radio resources. In the uplink direction, the apparatus sends a request to a downlink node to communicate using a specified allocation of radio resources, and receives from the downlink node a grant to communicate using at least a portion of the specified allocation of radio resources.

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.
