Reverse Link, Closed Loop Power Control Method of Code Division Multiple Access System

摘要

The method of the present invention allows the mobile radiotelephone to operate with a 100% impact factor and provide closed loop power control. The base station measures the signal-to-noise ratio of the signal from the mobile device and compares the SNR with the SNR limit value that the mobile device has for each data rate it can transmit (305). The base station generates a power control command 310 to cause the mobile device to change its power depending on the result of the comparison.
