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: In a wireless communication system, a user equipment, already configured with a first medium access control (MAC) entity for a master cell group (MCG) associated with a master base station, capable of configuring a secondary cell group (SCG) associated with a secondary base station based on a radio resource control (RRC) message received from the master base station. The user equipment can configure a second MAC entity for the newly configured SCG. Through a second RRC message from the master base station, the user equipment can then add a new SCG cell to the SCG, where the second MAC entity is commonly configured for one or more secondary SCG cells belonging to the SCG.

Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: A method and apparatus for scheduling uplink (UL) transmission in a wireless communication system is provided. A user equipment (UE) receives a backoff parameter from a network, and determines whether or not to apply the received backoff parameter before transmitting a scheduling request (SR) to the network via a dedicated channel. Whether or not to apply the received backoff parameter is determined according to a prioritized access, and the prioritized access corresponds to one of emergency access, high priority access, control element/information in media access control (MAC), radio link control (RLC) or packet data convergence protocol (PDCP), data radio bearer (DRB) for voice/video service, signaling radio bearer (SRB) 0, SRB 1, SRB 2, multimedia telephony service (MMTEL)-voice, MMTEL-video, and voice over long-term evolution (VoLTE).

Abstract: A method is presented for performing a device-to-device (D2D) operation by a first user equipment (UE) in a wireless communication system. The first UE receives configuration information of an evolved-universal mobile telecommunications service (UMTS) terrestrial radio access network (E-UTRAN) planned mode for the D2D operation from an evolved NodeB (eNB). The E-UTRAN planned mode is a D2D mode in which the eNB controls radio resources for the D2D operation. The UE performs the D2D operation with a second UE by using the radio resources in the E-UTRAN planned mode.

Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.
