    • A method for determining attenuation settings across carriers in a return link bandwidth of a user terminal comprises determining a first attenuation setting for a user terminal at a first transmission frequency, where the first attenuation setting is based on a first signal quality metric value of a first message sent from the user terminal at the first transmission frequency. The method also comprises determining a second attenuation setting for the user terminal at a second transmission frequency, where the second attenuation setting is based on a second signal quality metric value of a second message sent from the user terminal at the second transmission frequency. The method also comprises determining the attenuation settings across the carriers in the return link bandwidth of the user terminal based on the first attenuation setting and the second attenuation setting.
    • 用于确定用户终端的返回链路带宽中的载波的衰减设置的方法包括以第一传输频率确定用户终端的第一衰减设置,其中第一衰减设置基于第一衰减设置的第一信号质量度量值 消息以第一传输频率从用户终端发送。 该方法还包括以第二传输频率确定用户终端的第二衰减设置,其中第二衰减设置基于在第二传输频率从用户终端发送的第二消息的第二信号质量度量值。 该方法还包括基于第一衰减设置和第二衰减设置来确定跨越用户终端的返回链路带宽中的载波的衰减设置。
