TRANSMITTING/RECEIVING APPARATUS AND METHOD THEREOF IN CODEBOOK BASED MULTIPLE ANTENNA SYSTEM

摘要

A transmission/reception apparatus and a method thereof in a codebook-based multiple antenna system is provided. In a transmission method in a codebook-based Multiple Input Multiple Output (MIMO) system, control information is received from a receiver. A codeword is determined within an Open-Loop (OL)-MIMO codebook where a Closed-Loop (CL)-MIMO codebook is reused based on the control information. At least one data stream is transmitted via at least one antenna using the determined codeword.
