In a wireless communication system where data transmission is performed between a base station and terminals, the base station individually generates, for each terminal, a bit map indicative of scheduling resource numbers to be allocated to terminals to which Localized transmission is applied, based on a resource-number mapping rule defined by providing individual resource block numbers to all resource blocks, taking resource block numbers of resource blocks for Distributed transmission as fixed values, and providing individual scheduling resource numbers to remaining resource blocks for Localized transmission except the resource blocks for Distributed transmission for each of scheduling resources corresponding to the number of aggregation.
