Abstract
Disclosed is a radio communication system in which transmission parameters, such as MCS of MBSFN, the number of subframes, and a transmission power of a reserved cell, are adaptively output, based on a unicast traffic volume in a MBSFN area, a number of terminals, and a number of cells of the MBSFN area, so that a system throughput in the MBSFN area is maximized while satisfying an MBSFN quality requirement condition.
