Methods of generating a data block in a mobile communication system

摘要

Disclosed is a method for generating a lower layer data block to be transmitted from a specific layer in a transmitting side to a receiving side in a mobile communication system. The method includes receiving an upper layer data block from an upper layer and generating a lower layer data block including at least part of the upper layer data block and a buffer status indicator indicating a status change of a data buffer associated with a group identifier corresponding to the upper layer data block. According to this data block generation method, states of buffers carrying upper layer data blocks are transmitted to a base station using minimum radio resources, thereby increasing system efficiency.
