US 2004/0063453 A1 · Outer loop transmit power control using channel-adaptive processing

Abstract

The present invention is a system and method which controls outer loop transmit power for transmission power of an uplink/downlink communication in a wireless communication system. The system receives a communication from a base station and determines an error rate on the received communication. The system then distinguishes between static and dynamic channels, produces a static adjustment value, and characterizes the dynamic channels to generate a dynamic adjustment value. The target power level is then adjusted by the static and dynamic adjustment values, setting the transmission power level.

Dependent claims

A method for controlling outer loop transmit power for transmission power control of an uplink/downlink communication in a wireless communication system where a user equipment (UE) produces a target power level based upon received signals which it communicates to a base station from which the signals are received, the method comprising the steps of:

receiving at the UE a communication in the form of a series of communication segments from a base station;
analyzing the received communication within first and second composite windows;
periodically distinguishing between static and dynamic channel conditions in communication segments within the first and second windows;
generating a static adjustment value when the respective channel conditions of the communication segments in said first and second windows are different;
and
adjusting the target power level in response to the static adjustment value.

3 more elements

A receiver in a wireless communication system where a user equipment (UE) produces a target power level based upon received signals which it communicates to a base station from which the signals are received, which controls outer loop transmit power for transmission power control of an uplink/downlink communication and receives a communication in the form of a series of communication segments from a base station, comprising:

an error detection device for determining whether an error is present in a transmission time interval (TTI);
and
a processor in communication with the error detection device, the processor for generating the target power level which is communicated to said base station and analyzing the received communication within first and second composite windows.
