Apparatus and method for allocating resources in a broadband wireless communication system
View Patent ↗The present invention relates to an apparatus and method for allocating a MAP message region in a broadband wireless communication system having a multi-cell/-sector structure. The present invention allocates a common MAP message region for multiple cells/sectors and a data region, divides the common MAP message region into MAP message sections for each of the cells or each of the sectors, allocates MAP messages corresponding to each of the cells or each of the sectors to the divided MAP message sections and allocates data to be transmitted to each MS to the data region, and broadcasts multiple frames containing MAP message regions for each of the cells or for each of the sectors and the data region.
1. A method for allocating resources in a broadband wireless communication system, the method comprising:
allocating a common MAP message region and a data region for multiple cells/sectors and segmenting the common MAP message region into sub-MAP message regions for each of the cells or each of the sectors;
allocating a MAP message corresponding to each of the cells or each of the sectors to each sub-MAP message region, and allocating data to be transmitted to each mobile station to the data region;
determining Modulation and Coding Scheme (MCS) level and repetition of the MCS level for each of the MAP messages; and
broadcasting multiple frames including the data region and the each sub-MAP message region for each of the cells or each of the sectors,
wherein the MCS level for the each sub-MAP message region allows for a lower repetition than if a repetition for the common MAP message region was applied to the common MAP message region as a whole.
2. The method of claim 1 , wherein the common MAP message region is a MAP message transmission region allocated to the entire frequency band in the multiple cells/sectors, and the each sub-MAP message region is a MAP message transmission region in which the entire frequency band is divided for each of the cells or each of the sectors.
3. The method of claim 1 , wherein divided frequency bands are allocated to the sub-MAP message regions, and wherein the divided frequency bands are corresponding to sub-MAP messages in a Frequency Assignment (FA).
4. The method of claim 1 , wherein the repetition of the MCS level for the MAP message is determined as 1 to 3.
5. The method of claim 1 , wherein the MAP message for each of the cells or each of the sectors is corresponding to the each sub-MAP message region.
6. The method of claim 1 , wherein the common MAP message region is segmented into three sub-MAP message regions and, wherein the first sub-MAP message region is allocated in a first frame, the second sub-MAP message region is allocated in a second frame, the third sub-MAP message region is allocated in a third frame.
7. The method of claim 1 , sizes of the sub-MAP message regions are determined by sizes of the MAP messages corresponding to each of the cells or each of the sectors.
