SYSTEM AND METHOD FOR DATA BURST COMMUNICATIONS IN A CDMA NETWORK

摘要

A method is provided for establishing outer loop power control in the transmission of data bursts in an IS-2000A standard CDMA system. The present invention was developed to address the problems of cell sensitivity and capacity degradation that are inherent in transmission of long messages. The present invention is based on the concept of joint re-transmitted message frame combining to adjust the outer loop setpoint. The inner loop power adjustment during the message transmissions uses the setpoint established by the outer loop function. The outer loop memory spans multiple message transmissions in that the setpoint adjustment during transmission of a message depends both on the adjustment performed during the previous message transmission and on the effective message length. The effective message length is reduced at each transmission attempt by means of the message re-transmission combining function. A system and apparatus which control the outer loop power function in accordance with the above-described method are also provided.
