Method of formatting signal in mobile communication system
First Claim
1. A method of data processing in a medium access control (MAC) layer of a receiving side, comprising:
- receiving, from a lower layer, a first type of medium access control protocol data unit (MAC-PDU) received from a transmitting side, the first type of MAC-PDU comprising a plurality of medium access control service data units (MAC-SDUs) and a single MAC header including a first identifier which is common to the plurality of MAC-SDUs and a second identifier for identifying a receiver of the first type of MAC-PDU, wherein the plurality of MAC-SDUs are successively coupled to the single MAC header, wherein the first identifier is used by the MAC layer of the receiving side to transfer the plurality of MAC-SDUs to an upper layer of the receiving side; and
receiving, from the lower layer, a second type of MAC-PDU received from the transmitting side, the second type of MAC-PDU comprising a plurality of MAC-SDUs and a plurality of MAC headers, wherein each of the plurality of MAC-SDUs in the second type of MAC-PDU is respectively coupled to each of the plurality of MAC headers in the second type of MAC-PDU,wherein the first type of MAC-PDU is formed by a MAC layer of the transmitting side when the plurality of MAC-SDUs in the first type of MAC-PDU have the same characteristics, and wherein the second type of MAC-PDU is formed by the MAC layer of the transmitting side when the plurality of MAC-SDUs in the second type of MAC-PDU have different characteristics.

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.
