Abstract
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).
