METHOD AND APPARATUS FOR INTERFERENCE ALLIGNMENT IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, comprises a process for selecting one terminal for providing a service to each small distributed base station based on information included in feedback and a process for determining a terminal assigned by combining the base stations by comparing the cooperation gains based on the information when a base station operating method comprises a feedback reception process and terminal assignment information in the wireless communication system, and provides advantages which reduce the complexity of terminal selection and cooperation type determination by enabling a main control unit or the small distributed base station to select the terminal and which reduce the feedback amount of channel information by enabling the terminals to return additional channel information to the base station. [Reference numerals] (310) Terminal;(320) Small distributed base station;(330) Central management unit;(a) Transmit a random beam to a terminal;(b) Create feedback information;(c) Feedback information;(d) Have the feedback information shared by small distributed base stations;(e) Assign a terminal for each small distributed base station and decide a transmission type;(f) Share terminal assignment information;(g) Terminal service
