Method for formatting signal in mobile communication system
First Claim
1. A method for formatting a medium access control-protocol data unit (MAC-PDU) in a mobile communication system, the method comprising:
- generating a medium access control (MAC) header comprising a medium access control layer service access point (MAC-SAP) identifier and length of MAC SDU andappending the MAC header to at least two successive medium access control-service data units (MAC-SDUs), if said at least two MAC-SDUs have the same characteristics,wherein the MAC-SAP identifier identifies a plurality of logical channels on which the MAC-SDUs are transferred through a MAC-SAP located between the logical channel and a MAC sublayer, and wherein the plurality of logical channels are mapped to a single transport channel.

Abstract
A method for formatting a signal in a mobile communication system by appending a plurality of medium access control headers to a plurality of medium access control-service data units for data transfer between a mobile station and network in the mobile communication system. If the service data units have the same characteristics, a medium access control-protocol data unit is formed by successively coupling the service data units to any one of the medium access control headers. If the service data units have different characteristics, the protocol data unit is formed by sequentially coupling each of the service data units and each of the medium access control headers. The formed protocol data unit is then transformed into a transport block with a predetermined size. A medium access control sublayer formats medium access control-protocol data units according to transport channel characteristics in peer-to-peer communication in such a manner that the protocol data units can have different formats with respect to different transport channels. This makes it possible to provide more efficient functions.

8. A method for formatting a medium access control-protocol data unit (MAC-PDU) in a mobile communication system, the method comprising:
-
generating at least two medium access control (MAC) headers comprising a first identifier; and appending the MAC headers to at least two medium access control-service data units (MAC-SDUs) by sequentially coupling each of said MAC-SDUs and each of said MAC headers, wherein the first identifier is adapted to identify a logical channel on which the MAC-SDUs are transferred through a MAC-SAP located between the logical channel and a MAC sublayer, and wherein the logical channel is mapped to a transport channel.
