METHOD AND APPARATUS FOR POWER CONTROL OF AN AIR INTERFACE TRANSMISSION

摘要

An apparatus (101) performs power control for an air interface transmission between a receiver (105) and a transmitter (103). The apparatus (101) comprises a power control processor (113) which operates a power control loop for the air interface transmission in response to an error parameter. A discarded data processor (117) determines a discarded data measure indicating an amount of data actively discarded for the air interface transmission; and an error parameter processor (115) determines the error parameter in response to the discarded data measure. The data may be discarded in response to an evaluation of a delay criterion. The invention may allow power control to dynamically adjust both error rate and delay characteristics for the transmission.
