    • Systems and methodologies are described that provide techniques for generating and utilizing reverse link feedback for interference management in a wireless communication system. Channel quality and/or interference data can be obtained by a terminal from a serving sector and one or more neighboring sectors, from which an interference-based headroom value can be computed that contains interference caused by the terminal to an allowable range. The interference-based headroom value can then be provided with power amplifier (PA) headroom feedback to the serving sector. Based on the provided feedback from the terminal, the serving sector can assign resources for use by the terminal in communication with the serving sector. Further, the serving sector may choose to honor or disregard a received interference-based power value based on quality of service and/or other system parameters.
    • 描述了提供用于在无线通信系统中生成和利用反向链路反馈用于干扰管理的技术的系统和方法。 信道质量和/或干扰数据可以由来自服务扇区和一个或多个相邻扇区的终端获得,从该终端可以计算包含由终端引起的干扰到允许范围的基于干扰的余量值。 然后可以向服务扇区提供基于干扰的净空值,功率放大器(PA)净空反馈。 基于提供的来自终端的反馈,服务扇区可以分配资源供终端与服务扇区进行通信。 此外,服务部门可以选择基于服务质量和/或其他系统参数来尊重或忽视接收到的基于干扰的功率值。
