FIELD: radio engineering, communication.
SUBSTANCE: disclosed is a method for performing uplink scheduling for an adaptive grant and polling (aGP) service in a broadband wireless access system. The method comprises steps of: transmitting a first message for requesting the switching or changing of a QoS (quality of service) parameter set to a base station; receiving, from the base station, a service specific scheduling control header (SSSCH) for adaptation of a new QoS parameter set; and switching or changing to the new QoS parameter set at the checked adaptation start time after checking the adaptation start time information within the specific scheduling control.
EFFECT: informing the terminal of a timing at which the base station is switched or changed when the quality of service parameter set of the relevant service is switched or changed at a specific timing in an adaptive grant and polling.
