Abstract :
Reverse link outer-loop power control (ROLPC) algorithms developed for voice systems operate based on a continuous stream of packets (CRC events) to adjust the power control setpoint. Due to burstiness of data traffic a mechanism to distinguish between idle periods and data transmissions is necessary in systems optimized for data communications. In addition, such algorithms are unable to track changes in channel conditions during long idle periods. The proposed algorithm is designed to conservatively adapt to the channel in the absence of packets, with fast convergence at the start of a transmission. A parameterized algorithm is described with analysis and simulation results to justify baseline parameters. The performance of the algorithm for continuous and bursty TCP/IP traffic is presented
