Common control channel uplink power control for adaptive modulation and coding techniques
First Claim
1. A user equipment (UE), comprising:
- a reference channel receiver for receiving a communication signal over a physical reference channel;
a path loss calculation device, responsive to the received communication signal, for calculating an expected path loss;
a signaling receiver for receiving an allocation of an uplink control channel including the amount of interference in the channel; and
a power level calculation device, responsive to said path loss calculation device and said signaling receiver, for determining an uplink power level based on said path loss and said interference level;
whereby an uplink control channel transmission is initiated having the power level determined by said power level calculation device.

Abstract
The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.
