Abstract
The present invention relates to a method of changing a frequency assignment (FA) status in an improved broadband wireless access system where terminals and base stations communicate with each other by using a plurality of FAs. The base station changes the status of one of secondary FA into the status of the pFA in order to adjust a load of the primary FA, and communicates with the terminal through the pFA of which status is changed. When a response is received from the terminal, the base station changes the status of the pFA and communicates with the pFA of the terminal through a new pFA. The status of a previous pFA between the base station and the terminal is changed into the status of the sFA, and a previous sFA is changed into the pFA, so that communication is performed through new FAs.
