Methods of transmitting data blocks in wireless communication system
First Claim
1. A method for generating a data block at a medium access control, MAC, layer of a transmitting side in a wireless communication system, the method comprising:
- receiving an upper layer data block from an upper layer; and
generating the data block including a MAC header and a MAC payload, wherein the MAC payload comprises at least part of the upper layer data block and the MAC header comprises one or more sub-headers,wherein each of the one or more sub-headers comprises;
a LCID (logical channel identifier) field being used to indicate an identifier of a logical channel through which the upper layer data block is received,a 1-bit state indication information field being used to indicate a state of the upper layer data block, wherein the 1-bit value of the state indication information field is interpreted differently according to a value of the LCID field, anda L (length) field being used to indicate a size of the at least part of the upper layer data block,wherein the state indication information field in one of the one or more sub-headers indicates whether the upper layer data block includes a full header or a compressed header when the LCID field in the same sub-header indicates the upper layer data block is received through a the logical channel related with an IP packet of the upper layer.

Abstract
Disclosed is a method for generating a data block to be transmitted from a specific layer in a transmitting side to a receiving side in a wireless communication system. The method includes receiving an upper layer datei block from an upper layer and generating a lower layer data block including at least part of the upper layer data block and state indication information indicating a state of the upper layer data block, the state indication information being selected variably according to a logical channel through which the upper layer data block is received. This method optimizes overhead of a header of each upper layer data block according to contents of the upper layer data block and event situations associated with the upper layer data block, thereby increasing system efficiency.
