    • User equipment (UE), referred to herein as an interfering UE (130), can be detected that is proximate to a low-power cell (120), such as a micro-cell, pico-cell, femto-cell, a relay, or the like. The interfering UE (130) can be transmitting to the base station (110) at a power level that is producing high interference affecting uplink performance between a different UE and the low-power cell (120). A power adjustment message (140) can be generated at the base station (110). The power adjustment message (140) can be conveyed (156) from the base station (110) to the interfering UE (130). The power level adjustment message (130) can cause the interfering UE (130) to lower its transmission power (164), which reduces the high interference, thereby improving uplink performance between the different UE and the low-power cell (120).
    • 可以检测在本文中称为干扰UE(130)的用户设备(UE),其接近低功率小区(120),例如微小区,微微小区,毫微微小区,中继 ,等等。 干扰UE(130)可以以产生影响不同UE与低功率小区(120)之间的上行链路性能的高干扰的功率电平向基站(110)发送。 功率调整消息(140)可以在基站(110)处产生。 功率调整消息(140)可以从基站(110)传送到干扰UE(130)(156)。 功率电平调整消息(130)可以使干扰UE(130)降低其发射功率(164),从而降低高干扰,从而改善不同UE与低功率小区(120)之间的上行链路性能。
