    • Methods and apparatus for wireless communications in networks, e.g., regional ad hoc peer to peer networks, are described. A communications node, e.g., a third node monitors for wireless communications between other peer communication nodes, e.g., a first node and a second node, in its local vicinity. The third node determines from the monitored wireless communication an indication of link quality corresponding to a communication link between the communication nodes which are communicating or seeking to establish a communications link. The third node generates an estimate of a link quality for a communications link between itself and the first node. Based on the indication of link quality and generated estimate of link quality, the third node decides whether or not to send a signal indicating availability to relay communication between the first and second nodes. The third node, when acting as an intermediary node after indicating its availability to so act, may receive traffic data e.g., user data communicated in a peer to peer traffic segment, from the first node. The third node communicates the received traffic data to the second node by transmitting the traffic data.
    • 描述了用于网络中的无线通信的方法和装置,例如区域自组织对等网络。 通信节点,例如第三节点监视在其本地附近的其他对等通信节点(例如,第一节点和第二节点)之间的无线通信。 第三节点从监视的无线通信确定与正在通信或寻求建立通信链路的通信节点之间的通信链路相对应的链路质量的指示。 第三节点产生对于其与第一节点之间的通信链路的链路质量的估计。 基于链路质量的指示和链路质量的产生估计,第三节点决定是否发送指示第一和第二节点之间的中继通信的可用性的信号。 第三节点在指示其可用性之后充当中间节点时可以从第一节点接收业务数据,例如在对等业务段中传送的用户数据。 第三节点通过发送业务数据将接收到的业务数据传送到第二节点。

    • Wireless communications devices, e.g., peer to peer mobile wireless terminals in and ad-hoc peer to peer communications network, support multiple modes of peer discovery operation. In different peer discovery transmit modes peer discovery information is transmitted at different rates. In different peer discovery receive modes peer discovery information is monitored at different rates. Performing peer discovery operations at a higher rate has the benefit of reducing discovery latency at the cost of utilizing more communications resources and expending more power. A communications device dynamically changes its mode in response to changing conditions and/or needs. Transitions between modes are in response to a determined change condition trigger occurrence. Various change condition triggers include, e.g., a user event, an application event, information received over the air interface, information derived from information received over the air interface and/or temporal information.
    • 无线通信设备,例如对等通信网络中的对等移动无线终端,支持对等体发现操作的多种模式。 在不同的对等体发现传输模式中,以不同的速率发送对等体发现信息。 在不同的对等体发现接收模式下,以不同的速率监视对等体发现信息。 以更高的速率执行对等体发现操作有利于减少发现延迟,代价是利用更多的通信资源和花费更多的功率。 通信设备根据变化的条件和/或需要动态地改变其模式。 模式之间的转换是响应确定的变化条件触发发生。 各种变化条件触发器包括例如用户事件,应用事件,通过空中接口接收的信息,从通过空中接口接收的信息导出的信息和/或时间信息。
