Abstract:
The present specification suggests a method for establishing a terminal-centric group cell on the basis of measurement signal variation for cooperative transmission and handover in a mobile communication system. Specifically, a base station receives transmissions of parameters from a terminal, configures a terminal surrounding cell information table, and configures a cooperative cell cluster configuration table using the terminal surrounding cell information table as the terminal moves. The base station performs cooperative transmission and handover using the cooperative cell cluster configuration table. The terminal sends parameters to the base station periodically or when a certain condition is met, and the base station updates the terminal surrounding cell information table and the cooperative cell cluster configuration table using the parameters sent from the terminal to thereby use the same for mobility management.
