System and method for power control

摘要

A method of operating base station includes determining a first transmit power of a user equipment (UE), which includes determining a serving base station receive power, determining a path loss of the UE to the base station, determining a downlink signal to noise and interference ratio (SNIR) at the UE, and forming the first UE transmit power. Forming the first UE transmit power comprises summing the serving base station receive power, the path loss of the UE to the base station and the downlink SNIR. The method further includes instructing the UE to transmit at the first UE transmit power.

1. A method comprising:
determining, by a power controller in a wireless network, a transmit power level of a user equipment (UE), wherein determining the transmit power level comprises:
determining a serving base station receive power,determining a path loss of the UE to the serving base station,determining a downlink signal to noise and interference ratio (SNIR) received by the UE, the downlink SNIR being a ratio of a transmit power of the serving base station received by the UE to noise and interference received by the UE, wherein determining the downlink SNIR received by the UE comprises receiving a measurement of the downlink SNIR from the UE,forming a first UE transmit power, wherein forming the first UE transmit power comprises summing the serving base station receive power, the path loss of the UE to the serving base station, and the downlink SNIR; andinstructing the UE to transmit at the first UE transmit power, wherein the downlink SNIR corresponds to an approximate difference between the power received at the serving base station from the UE and the sum of the interference caused by the UE at neighboring base stations.
