Summary :

In this letter, we propose the reducing method of feedback information for transmitting adaptable data rate in multi-user OFDMA/FDD system. In order to transmit the downlink channel information to Base-Station (BS) by using the limited uplink control channel, the proposed algorithm uses the channel variation level which describes the similarity among the adjacent clusters and uses just one modulation and coding scheme (MCS) level which represents the channel information of all clusters. The performance was investigated in one-cellular environment. It has a similar overhead for feedback information with conventional algorithm and has better performance than the conventional algorithm.
