In this paper, a downward system has cell and dual frequency division characteristics has been considered in which each user send state information of information channel to its home station. Since the cooperation between all stations is not possible in practice, a number of stations are grouped into clusters and users should estimate their own channel by sending pilots to base station and feedback channel state information to the station. Until the station has no receive the channel information of all users, prevents to send it that it cause delay in sending data at downward system.
