Abstract

The present invention is directed to a method for setting a user equipment identifier as user equipment identification information used when data received through a dedicated logical channel is transmitted through a common transport channel. The method includes transmitting data and a message type indicator as user equipment identification information from a RRC layer to an RLC layer; setting a user equipment identifier indicator according to the received message type indicator in the RLC layer and transmitting it with the data to a MAC layer; and selecting a user equipment identifier type and a user equipment identifier according to the set user equipment indication identifier, adding it to a header of a MAC SDU in the MAC layer and transmitting it to a corresponding MAC layer in a receiving device.
