Abstract
A method for allocating reverse and forward channel power in a W-CDMA WLL system is disclosed. The method comprises calculating a propagation path loss of forward and reverse pilot channels depending on the maximum path loss of forward and reverse links for a base station located at a specific distance from a terminal, determined from the minimum Ec/It required by the system, the transmission antenna gain of a terminal, the reception antenna gain of the terminal, the reverse frequency reusing efficiency, the transmission output of the terminal, the number of active users, the power allocation ratio of the pilot channel, the bandwidth, and the thermal noise density; and, calculating a power allocation ratio of forward and reverse channels depending on the propagation path loss of the forward and reverse pilot channels, Eb/Nt of the forward and reverse channels, the power allocation ratio of the forward and reverse pilot channels, the data rate of the forward and reverse channels, the bandwidth, and the reverse frequency reusing efficiency
