APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING DATA IN COMMUNICATION SYSTEM

摘要

PURPOSE: A data transmission and reception apparatus and method thereof are provided to rapidly and stably transmit and receive massive data using a beam forming method according to an MIMO(Multiple Input Multiple Output) method in a communication system. CONSTITUTION: A transmission unit(840) transmits an NDPA(Null Data Packet Announcement) frame and an NDP(Null Data Packet) frame to a terminal for obtaining the channel information of a terminal for transmitting and receiving data using a beam forming method according to an MIMO method. A reception unit(810) receives a beam forming frame from the terminal by responding to the NDPA frame and the NDP frame. A confirmation unit(820) confirms direction information for the normal reception of the NDP frame. The NDP frame includes the control information filed of the beam forming frame.
