A method and an apparatus of a coordinator forming a coordinated communication system for enhancing cell edge terminal throughput are provided. The method includes receiving information on Sound Reference Signal (SRS) reception power at a terminal for respective cells of a scheduler belonging to the coordinator from the scheduler, generating terminal distinction information for indicating whether a terminal is a cell edge terminal based on the SRS reception power information or Signal to Interference plus Noise Ratio (SINR) estimated from the SRS reception power information, generating interference relationship information between terminals and cells based on the SRS reception power information or estimated SINR, and transmitting the terminal distinction information and interference relationship information to the scheduler.
