Abstract:
1. A method for performing persistent allocation by a base station in a broadband wireless access system, the method comprising: determining a size and a position of persistent allocation resources to be allocated through persistent allocation; comparing the size and the position with a previously determined size and a previously determined position of the allocated persistent allocation resources; and transmitting a MAP information element (A-MAP IE) to a user equipment (UE), the A-MAP IE including a resource allocation indicator field established according to the comparison result, the resource allocation indicator field indicating whether an allocation size field indicating the size of persistent allocation resources and a resource offset field indicating the position of persistent allocation resources as an offset value are included in the A-MAP IE, wherein, when the size is different from the previously determined size of the allocated persistent allocation resources, and when the position is not consecutive to the previously determined position of the allocated persistent allocation resources, the resource allocation indicator field is set to a first value, and the A-MAP IE includes the resource offset field and the allocation size field, and wherein, when the size is the same as the previously determined size of the allocated persistent allocation resources, and when the position is consecutive to the previously determined position of the allocated persistent allocation resource, the resource allocation indicator field is set to a second value, and the resource offset field and the allocation size field are excluded from the A-MAP IE.
