<p>PURPOSE: A communication device in a high-capacity wireless communication system is provided to improve wireless communication service performance by applying multiple antenna system for each channel. CONSTITUTION: A high rank mapper unit(810) receives data to be transferred to a terminal, and an access number about the priority of a connecting point from the higher layer of the MAC layer. A lower rank mapper unit(830) maps again the mapping data which is mapped by the high rank mapper unit by the categories using each channel state information. A low rank memory unit buffers the mapped data in the lower mapper unit in order to transmit the mapped data to a physical layer. The memory unit comprises a plurality of queues for the connection categories classified by each connecting point.</p> |
