METHOD FOR REPORTING BUFFER STATUS OF TERMINAL AND APPARATUS THEREFOR IN SYSTEM IN WHICH HETEROGENEOUS WIRELESS COMMUNICATION TECHNOLOGIES ARE UTILIZED

摘要

The present invention relates to a method for reporting a buffer status and an apparatus therefor in a heterogeneous wireless communication system. A terminal receives a configuration message for a multi-RAT integration scheduling from a cellular controller, and, on the basis of the configuration message, can report the buffer status in a format comprising identification information for a logic channel and a multi-RAT scheduling indication field.
