摘要： An apparatus and method for estimating a MAP size in a broadband wireless communication system based on FFR are provided. In the method, one of a plurality of connections is selected according to priority between the connections. An available resource condition and a MAP size for allocation of resources for the selected connection is determined if resources acceptable for a burst are present in a zone including the selected connection. The next connection is selected according to the priority if available resources are present. The determined MAP size is determined as the final estimation value of a MAP size if the available resources are not present.

摘要： A resource allocation method of a Base Station (BS) in a wireless communication system is provided. The method includes estimating a size of a MAP message, and evaluating a size of an available burst allocation region according to the estimated size of the MAP message and allocating bursts in the evaluated-sized burst allocation region.

摘要： A scheduling apparatus for a base transceiver system (BTS), determines a point of data transmission to mobile stations (MSs). The BTS includes buffers for storing data to be transmitted to the MSs. A scheduler determines a priority of each of the MSs taking into account a data rate determined depending on a channel condition between the BTS and the MSs, a required amount of transmission data, and an amount of data to be transmitted to the MSs, and determines an MS having the highest priority among the MSs, as a destination MS to which data is to be transmitted by the BTS. The scheduler increases the required amount of transmission data upon receipt of a retransmitted data packet, and decreases the required amount of transmission data after transmitting data to the MSs.
