An MS with a high priority level is selected according to the calculated scheduling metric. The number of subchannels and a product of a modulation order and coding rate (MPR) are extracted according to input variables for the selected MS. The number of subchannels to be allocated to the selected MS is determined according to the MPR and the subchannels are allocated to the selected MS. The scheduling metric is updated for the each MS.

    摘要: Provided is an apparatus and method for allocating radio resources in a broadband wireless communication system by adaptively grouping the radio resources. In the method, the amount of resources necessary for a transmission of data to a user terminal and the amount of the remaining allocable resources are detected. A resource allocation scheme is selected in consideration of the amount of resources necessary for the transmission of the data to the user terminal and the amount of the remaining resources. A group index of radio resources for the user terminal is determined according to the selected resource allocation scheme. Radio resources corresponding to the determined group index are allocated to the user terminal.

    摘要: An apparatus and method for Hybrid Automatic Repeat reQuest (HARQ) signaling in a broadband wireless communication system are provided. A communication method of a Base Station (BS) includes transmitting a Fixed Allocation (FA) message containing bitmap index information for all Mobile Stations (MSs) allocated with fixed resources; and transmitting bitmap information indicating whether packets to be transmitted to the MSs are Retransmission (Rtx) packets or new packets. Accordingly, when HARQ is carried out using a fixed resource allocation scheme, a bitmap is used to indicate whether HARQ packets transmitted in a current frame are new packets or Rtx packets. Therefore, a receiving end can be prevented from incorrectly decoding the packets.
