METHOD OF CONSTRUCTING RESOURCE ALLOCATION MAP FOR MOBILE COMMUNICATION SYSTEM
First Claim
1. A method of constructing a resource allocation map in a case where a base station allocates a radio resource to a plurality of mobile terminals by using a localized resource block in a mobile communication system, the localized resource block being a localized sub-channel composed of neighboring sub-carriers, the method comprising:
- including a mobile terminal identifier column where identifiers of the mobile terminals are continuously displayed, in the resource allocation map;
setting an index for each mobile terminal according to an order in which the mobile terminal identifiers are displayed, and allocating an index of a mobile terminal corresponding to each of resource blocks of the radio resource for each resource block, the resource block being a unit of a minimal radio resource found by dividing a radio resource used when data is transmitted; and
including an index bit pattern where indexes allocated for the individual resource blocks are arranged according to an order of the resource blocks included in the radio resource, in the resource allocation map.

Abstract
The present invention relates to a method of constructing a resource allocation map in a mobile communication system. In a method of constructing a map in a hierarchial pattern method in a case where a localized resource block (localized RB) and a distributed resource block (distributed RB) need to be simultaneously allocated in regards to a radio resource allocated in a previous frame or reserved with a fixed allocation, a radio resource that is reserved or not used and a radio resource that is newly allocated in a map of a current frame are classified and represented. Then, in regards to a radio resource that is allocated in a current frame, a localized RB and a distributed RB are classified and represented. As for the localized RB, allocation information is represented in an index pattern method, and as for the distributed RB, resource allocation information is represented in a toggle pattern method.

19. A method of constructing a resource allocation map in a case where a base station in a mobile communication system allocates a radio resource by using sub-maps and a main map, the sub-maps including radio resource allocation information for mobile terminals, the main map including information for a location of the radio resource used for transmission of the sub-maps and a modulation and coding scheme, the method comprising:
-
constructing a bit column including classification information corresponding to a resource block allocated in a current frame in the entire radio resource, the resource block being a unit of a minimal radio resource found by dividing a radio resource used when data is transmitted, and including the bit column in the man map; including a localized resource block bit pattern including classification information of a localized resource block corresponding to the resource block allocated in the current frame and a distributed resource block, in the main map; and including sub-map usage information corresponding to whether the sub-maps are used, in the main map, and classifying a sub-map localized resource block and a sub-map distributed resource block for each sub-map when the sub-maps are used. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
