1. A method of transmitting a buffer status report (BSR) in a multi-radio access technology (RAT) system including a cellular network and a wireless local area network (WLAN) by a multi-RAT user equipment (UE), the method comprising:
- receiving a setup message of multi RAT integration scheduling from a cellular controller,wherein the setup message of the multi-RAT integration scheduling includes condition information including a time threshold value which is a reference value to be compared with an access time, andwherein the access time is a time interval during which a BSR is transmitted through the WLAN;
transmitting a multi-RAT integration BSR to the cellular controller based on the setup message when the access time exceeds the time threshold value; and
transmitting a data through resources that are dynamically allocated resources of the cellular network and the WLAN based on the multi-RAT integration BSR.

Abstract
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.
