Methods of generating data block in mobile communication system
First Claim
1. 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 comprising:
- 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 of a data buffer associated with a group identifier corresponding to the upper layer data block,wherein the group identifier indicates a group including a plurality of data service passages,wherein the buffer status indicator indicates whether or not the amount of data stored in the data buffer is greater than the total amount of data that can be transmitted for a time specified based on the amount of currently allocated radio resources,wherein the number of bits used to indicate the buffer status indicator is different for each group, andwherein the number of bits used to indicate the buffer status indicator is provided through system information.

Abstract
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.
