    • Systems and methodologies are described that facilitate indicating a dominant interferer to a target serving base station in a wireless communication environment. A mobile device can detect presence or absence of a dominant interferer. Further, an access probe that includes information related to the presence or absence of the dominant interferer can be generated. For example, the information can be included in a payload of the access probe as an explicit flag, an explicit indication of an interference level, a Channel Quality Indicator (CQI) value (e.g., reserved versus non-reserved,...), etc. Moreover, the access probe can be transmitted to the target serving base station to initiate an access procedure. The target serving base station can select a time-frequency resource to be utilized for a responsive downlink transmission (e.g., access grant signal, subsequent access related message,...) as a function of the information included in the access probe.
    • 描述了有助于在无线通信环境中向目标服务基站指示显着干扰的系统和方法。 移动设备可以检测是否存在主要干扰源。 此外,可以生成包括与主要干扰源的存在或不存在有关的信息的接入探测。 例如,可以将信息作为显式标志,干扰水平的明确指示,信道质量指示符(CQI)值(例如,保留与非保留,...)一起包括在接入探测的有效载荷中, 等等。而且,接入探测可以被发送到目标服务基站以发起接入过程。 目标服务基站可以根据包括在接入探测中的信息来选择要用于响应下行链路传输(例如,接入准许信号,后续接入相关消息,...)的时间 - 频率资源。

    • Systems and methodologies are described herein that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system. As described herein, a network device can measure and report interference corresponding to network nodes outside a designated set of nodes that can cooperatively serve the device. Respective interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of respective nodes, or the like. Subsequently, respective interference reports can be combined with per-node channel information to manage coordination and scheduling across respective network nodes. As further described herein, interference from a network node can be measured by observing reference and/or synchronization signals from the network node. To aid such observation, respective non-interfering network nodes can define null pilot intervals in which transmission is silenced or otherwise reduced. As additionally described herein, loading information broadcasted by respective interfering network nodes can be identified and utilized in connection with interference calculation.
    • 这里描述了促成网络多输入多输出(N-MIMO)通信系统中的干扰测量和报告的系统和方法。 如这里所描述的,网络设备可以测量和报告与协作地服务该设备的指定的一组节点之外的网络节点相对应的干扰。 各个干扰报告还可以识别显性干扰节点,各个节点的发射天线之间的相关性等。 随后,各个干扰报告可以与每个节点的信道信息组合以管理各个网络节点之间的协调和调度。 如在此进一步描述的,来自网络节点的干扰可以通过观察来自网络节点的参考和/或同步信号来测量。 为了帮助这种观察,各个非干扰网络节点可以定义其中传输被静音或以其他方式减少的空导频间隔。 如此处另外描述的,可以结合干扰计算来识别和利用由各个干扰网络节点广播的负载信息。

    • Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.
    • 描述了通过中继站支持数据传输的技术。 在一方面,可以使用ACK和挂起来支持数据传输。 发送站发送分组的第一次发送到接收站。 发送台不接收用于分组的第一次发送的ACK信息,并且暂停分组的发送。 然后,发送站接收到恢复分组的发送的指示,并且作为响应,发送分组的第二发送。 在另一方面,当适用时可以使用不同的ACK时间线。 如果可以使用或在不同的子帧中,则接收站可以在指定的子帧中发送ACK信息。 在另一方面,可以使用ACK重复。 接收机可以在多个子帧中发送ACK信息,以便当发射机站不能接收多个子帧中的一个或多个时,接收ACK信息。
