The present invention relates to a method for forming a cluster-based network structure and an apparatus therefor, in which one or more clusters are configured based on path loss values between terminals located in a base station cell, and a representative terminal is selected for each cluster, and the representative By transmitting and receiving data between the base station and the terminals through the terminal, it is possible to increase the energy efficiency of all terminals located in the base station cell.
In particular, through the gradual clustering technique and the path loss-based clustering technique described in the embodiments of the present invention, a clustering technique having higher energy efficiency than the conventional clustering technique is introduced, and the energy efficiency of all terminals located in the base station cell is introduced. Can be effectively increased.
