APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA FRAME PROCESSING RESULT IN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for forming a physical channel for transmitting a processing result of a received data frame in an orthogonal frequency division multiple access (OFDMA) mobile communication system.

SOLUTION: The method includes selecting an orthogonal codeword corresponding to the processing result among predetermined orthogonal codewords, and transmitting the selected orthogonal codeword through at least one subcarrier group assigned for transmitting the processing result. A length of the orthogonal codeword is determined according to a number of symbol units included in the subcarrier group, and the predetermined orthogonal codewords are orthogonal to each other.
