DATA PROTECTION IN A MULTI-USER MIMO BASED WIRELESS COMMUNICATION SYSTEM CAPABLE OF IMPROVING THROUGHPUT OF A WIRELESS LAN SYSTEM

摘要

PURPOSE: A data protection in a multi-user MIMO based wireless communication system is provided to efficiently protect multi-user MIMO data by exchanging an RTS(Request To Send) and a CTS(Clear To Send) frames. ;CONSTITUTION: A wireless transmission terminal transmits a transmission requested frame to one or more wireless receiving terminals. The wireless transmission terminal respectively receives a transmission approval frame from one or more wireless receiving terminals. The transmission request frame comprises a VHT(Very High Throughput) data indicator for protecting a VHT traffic. The transmission request frame is an RTS frame. The transmission approval frame is a CTS frame.;COPYRIGHT KIPO 2011
