Abstract:
Provided are a method for generating a preamble included in a frame of a Multi-User Multi-Input Multi-Output (MU-MIMO) system, and a data transmission apparatus and terminal in which the method is adopted. The data transmission apparatus may enable at least one Very High Throughput-Long Training Field (VHT-LTF) sequence to be included in at least one Space Time Stream (STS) transmitted to at least one terminal, and transmits the at least one VHT-LTF sequence. The at least one VHT-LTF sequence may have the same length as another VHT-LTF sequence simultaneously transmitted.
