A method and apparatus for efficient open loop power control in a packet data mobile communication system using Frequency Division Multiple Access (FDMA) is disclosed. When a target Signal-to-Interference Ratio (SIR) required for the determination of transmission power using open loop power control is set, influence upon neighboring cells is considered. In other words, when a Mobile Station (MS) is located at a cell boundary and thus induces large interference with its neighboring cells, the target SIR is set low. In the other case, the target SIR is set high. Therefore, by adjusting transmission power according to the position of an MS and a relationship between the MS and the neighboring cells, support for high data rate can be provided to an MS that is located near a Base Station (BS) and interference induced by an MS that is located around a cell boundary can be minimized. In this way, the entire system capacity can also be improved. |
