Abstract: PURPOSE: A composing apparatus and method thereof in the maximum diversity multiplexing gain protocol for the cooperation wireless telecommunication and interference symbol system. In order to use the hierarchical modulation technique in the case in which the overlapping symbol is necessary it is offered. CONSTITUTION: A sender transmits the early knowledge(S201). In sender, the overlapping symbol confirms whether the point of time when being necessary or not. If it is not the point of time when the overlapping symbol is necessary, sender transmits the general symbol which becomes to the general modulation(S203). If the overlapping symbol is the point of time when being necessary, sender transmits the layer symbol which becomes to the hierarchical modulation(S205).

Abstract: A resource allocation method according to the modulation of a mobile communications system is provided to determine the size of a transmission block and the number of a resource block according to the modulation method in a 3GPP LTE(3rd Generation Partnership Project Long Term Evolution) system. A modulation system and coded system are determined according to a CQI(Channel quality information)(S320). The number of allocated resource blocs is determined according to a modulation method with reference to a resource allocation table(S330). The resource allocation table stores the number of transferable bits corresponding to the number of resource blocks. The number of bits multiplexes the number of resource blocks, the number of resource units used for data transmission by resource block.
