APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING MULTIPLE USER-MULTIPLE INPUT MULTIPLE OUTPUT RESOURCE ALLOCATION INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for transmitting and receiving multiple user-multiple input multiple output resource allocation information in a wireless communication system are provided to increase the amount of resource for the transmission of MU-MIMO data burst by minimizing the amount of resource for the transmission of MU-MIMO resource allocation information. CONSTITUTION: A-MAP IE which is allocated with MU-MIMO resources and classified into users is produced The A-MAP IE is transmitted in the position of one resource allocation location is transmitted as a SDMA(Spatial Division Multiple Access) manner. A MU-MIMO data burst and the produced the A-MAP IE are mapped in the same resource area . The same resource area is subband made of SLRU(Subband Logical Resource Unit). The A-MAP IE is mapped with the subband in a SDMA mode. The MU-MIMO data burst is mapped in the remaining area except for the mapped area of the A-MAP IE.
