METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA STREAMS IN A WIRELESS SYSTEM

摘要

PURPOSE: A data stream transmission and reception method and a device thereof are provided to execute a mapping for logical channels of additional physical layer slots according to the construction of a logical channel defined as a single input or multiple input encoding methods. CONSTITUTION: A reception unit receives data streams. A control unit maps the received data streams on an additional physical slot. The control unit constructs one or more frames including the additional physical slot. A transmission unit transmits the one or more frames through one or more wireless frequencies. The additional physical slot includes bit information which indicates the number of antennas transmitting the one or more frames.
