METHOD AND APPARATUS FOR UPLINK FAST FEEDBACK INFORMATION TRANSMISSION IN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEMS

摘要

The present invention relates to a method and apparatus for transmitting a fast feedback information in the control information in the uplink in an orthogonal frequency division multiple access system. For this, in a communication system The present invention, using an orthogonal frequency division multiple access method, a method of transmitting uplink fast feedback information using a fast feedback channel, and generating the uplink fast feedback information to be transmitted, the high-speed corresponding to the feedback information that the minimum Hamming distance for any pair among all of the possible two code words are output the code word having the maximum process and an orthogonal modulating transmission symbols corresponding to the output code word, and the orthogonal It converts the modulated transmission symbols are allocated to a sub-carrier process and the bundle, the transmission signal composed of said sub-carriers and inverse fast Fourier bundle, and transmitting the transmission signal by the inverse fast Fourier transform. ; OFDMA, the uplink fast feedback information, M-ary, channel coding, modulation and demodulation, non-coherent.
