METHOD AND APPARATUS FOR TRANSMITTING A SPATIAL STREAM FOR MU-MIMO IN A WIRELESS LOCAL AREA NETWORK SYSTEM

摘要

PURPOSE: A space stream transmitting method and an apparatus thereof for MU-MIMO(Multi User-Multiple Input Multiple Output) are provided to transmit space stream for MU-MIMO and to efficiently indicate space stream in a wireless LAN system. CONSTITUTION: An RF(Radio Frequency) unit(1630) is combined with a processor(1610). The RF unit transmits a frame. The processor transmits a management frame including group information to a receiver. The group information is information for allocating a location of a space stream. The processor transmits a frame including the space stream to the transmitter. [Reference numerals] (1610) Processor; (1620) RF unit; (1630) Memory
