Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) determines whether transmission of a first random access (RA) preamble to a first node and transmission of a second RA preamble to a second node overlap each other at a specific time duration. If it is determined that the transmission of the first RA preamble and the transmission of the second RA preamble overlap each other, the UE determines whether both the transmission of the first RA preamble and the transmission of the second RA preamble are available at the specific time duration based on an uplink power. If not available, the UE transmits the first RA preamble only at the specific time duration.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. In one embodiment, a user equipment (UE) determines a required amount of repetitions for uplink transmissions during a random access procedure, and performs repetitions for uplink transmissions based on the determined required amount of repetitions for uplink transmissions. The uplink transmissions may include transmission of preambles which are grouped. In another embodiment, a UE configures a communication windows for lost-cost machine-type communication (MTC) UE, and performs a random access procedure through the configured communication window.

Abstract: A method for changing a coverage enhancement (CE) mode at a user equipment (UE) in a wireless communication system in a wireless communication system is disclosed. The method includes steps of determining a CE mode level to be changed, transmitting a CE mode change request message to a network based on the determined CE mode level, and receiving a CE mode change message from the network via a physical downlink control channel. Especially, when the determined CE mode level is greater than a current CE mode level, a random access preamble associated with the determined CE mode level is transmitted to the network as the CE mode change request message.

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.

Abstract: Provided in one aspect is a method for handling a frequency priority performed by a terminal in a wireless communication system. The method comprises: receiving minimum priority application request information from a network; and handling a frequency priority for cell reselection on the basis of the minimum priority application request information and the supporting characteristics of the terminal. The minimum priority application request information indicates an application of the minimum priority to a current frequency of the terminal or all frequencies of current radio access technology (RAT) of a cell which the terminal camps on. The supporting characteristic of the terminal is whether the terminal supports the RAT other than the current RAT. The handling of the frequency priority is a variable application of the frequency priority for the cell reselection according to the contents of the minimum priority application request information and the supporting characteristics of the terminal.
