Abstract: A method and apparatus for receiving extended access barring (EAB) parameters in a wireless communication system is provided. A user equipment (UE) receives an EAB parameter, and receives an EAB parameter modification. The received EAB parameter is invalidated upon receiving the EAB parameter modification. The UE also waits for applying EAB until modified EAB parameter is received, and receives the modified EAB parameter.

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.

Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).

Abstract: There is provided a method for random access procedure. The method may comprise: determining, by a user equipment (UE), a first subframe on which a first random access preamble is to be transmitted to a first node; determining, by the UE, a second subframe, on which a second random access preamble is to be transmitted to a second node, except for the first subframe; and transmitting, by the UE, the first random access preamble on the first subframe and the second random access preamble on the second subframe.
