摘要： The present invention relates to a power control method for forward links in the CDMA cellular mobile communication system and a structure of a mobile station and a base station for the control. The power control method for forward links and a structure of a base station and a mobile station for the control in the CDMA cellular mobile communication system is presented which can increase forward link capacity as a mobile station measures signals of forward traffic channels from base stations in soft handoff and requests power increase/decrease divided for each corresponding base station and the base station adjusts transmit power of corresponding traffic channels depending on the forward link state.

摘要： A method for shedding traffic load in a code division multiple access mobile communication system, the method performing a soft handoff operation using the ratio of the received forward link pilot signal power to the sum of all interference signals power to transfer a portion of traffic load in the present serving cell with a high traffic density to an adjacent cell with a low traffic density. When the amount of traffic load in the present serving cell is increased and thus exceeds a link capacity of the present serving cell, handoff parameters of all mobile stations in the present serving cell can be updated on the basis of a power allocation state managed by a base station without reducing the coverage of a forward link. On the basis of the updated handoff parameters, the soft handoff operation is performed from a part of the mobile stations in the present serving cell with the high traffic density (for example, mobile stations at the edge of the present serving cell) to the adjacent cell with the low traffic density. Therefore, the excessive traffic load amount in the present serving cell can effectively be shed.

摘要： The present invention relates to a method and apparatus of a forward traffic channel power control for a code division multiple access (CDMA) wireless local loop system not having a hand-off function. The present invention distinguishes between a normal mode and a threshold mode in a CDMA wireless local loop. Here, the total power is lower than a predetermined power threshold value in the normal mode, and the total power arrives at the predetermined power threshold value in the threshold mode. In addition, the present invention varies method of increasing/reducing the forward traffic channel power according to the determined mode. As a result, method and apparatus according to the present invention effectively reduces the forward link interference signal at nearby cells, and provides a proper traffic quality.
