Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) determines one random access configuration from a first random access configuration for a normal type of UE and a second random access configuration for a specific type of UE, and transmits a random access preamble based on the second random access configuration to an eNodeB (eNB) if the UE is a specific type of UE. Also, a method and apparatus for establishing, by a UE, a connection in a wireless communication system is provided. The UE transmits a connection request message including bandwidth related information to the eNB.
