無線通信システムにおいて論理チャネルグループ拡張のためのバッファ状態報告を送信する方法及びそのための装置

Abstract

The present invention discloses a method for operating a User Equipment (UE) in a wireless communication system, which includes the steps of receiving uplink resources, allocating the uplink resources to at least two logical channels belonging to at least two Logical Channel Groups (LCGs), determining whether the size of the remaining uplink resources after allocation is smaller than a size of a long truncated BSR, which is a zero buffer size field plus a corresponding subheader, based on a size of the remaining uplink resources being equal to or larger than a size of a short buffer status report (BSR) plus a corresponding subheader and smaller than a size of a long BSR plus a corresponding subheader, and transmitting a short truncated BSR based on the uplink resources, based on the size of the remaining uplink resources being smaller than a size of the long truncated BSR, which is a zero buffer size field plus a corresponding subheader, and the at least two LCGs having available data for transmission.
