Abstract: A user equipment (UE) may compute uplink power control levels as a function of a downlink signal to noise ratio (SNIR). For example, the UE may determine an uplink transmit power level by summing a full power control (FPC) transmit power level, a product of a first adjustment factor (β) and the downlink SNIR, and a negative of a second adjustment factor (Δ2) when the product of the first adjustment factor (β) and the downlink SNIR is greater than or equal to the second adjustment factor (Δ2). A UE may also compute an uplink power control level as a function of target and/or current interference levels associated with neighboring base stations. A UE may also iteratively reduce a transmit power level until an interference level experienced by a neighboring base station has fallen below a threshold.

Abstract translation: 用户设备（UE）可以计算作为下行链路信噪比（SNIR）的函数的上行链路功率控制级别。 例如，UE可以通过将全功率控制（FPC）发射功率电平，第一调整因子（＆bgr）和下行链路SNIR的乘积和第二调整因子（＆lt; bgr）的乘积相加）来确定上行链路发射功率电平 ＆Dgr; 2）当第一调整因子（＆bgr）和下行SNIR的乘积大于或等于第二调整因子（＆Dgr; 2）时。 UE还可以计算作为与相邻基站相关联的目标和/或当前干扰电平的函数的上行链路功率控制级别。 UE还可以迭代地降低发射功率电平，直到相邻基站所经历的干扰水平已经低于阈值。
