Abstract

An apparatus for determining modulation and coding schemes (MCS) allocates a plurality of feedback channels to a multicast group to which a plurality of terminals belong. The apparatus receives the feedback signal through one feedback channel selected according to the channel quality indicators of each terminal among a plurality of feedback channels from each terminal belonging to the multicast group, and determines the MCS for the multicast data from the feedback signal received in the plurality feedback channels.
