Abstract
The present invention relates to a method for controlling a data rate for a forward data service in a CDMA 2000-1x system. Conventionally, the data rate from a base station to a mobile station is constant regardless of the wireless environment of the mobile station. As such, resources used in the base station for communication with the mobile station may be wasted if the data throughput is low due to the poor wireless environment. The present invention, however, resolves this problem by varying the data rate according to Energy of Carriers/Interference of Others' (Ec/Io) of the data, which indicates the wireless environment of the mobile station. With the present invention, the resources in a base station, which would be wasted for communication with a mobile station in a poor wireless environment, can be used for other mobile stations. Thus, the resources of the overall CDMA 2000-1x system can be used efficiently.
