Abstract: Disclosed are a method by which a terminal receives an MBMS service and an apparatus for supporting the same. The method comprises the steps of: determining a coverage enhancement (CE) level of the terminal in a frequency at which an MBMS service of interest is provided; receiving a CE level of the MBMS service supported by a network; determining whether the MBMS service can be received by comparing the CE level of the terminal with the CE level of the MBMS service; and reporting, to the network, the CE level of the terminal or the number of iterations, which is indicated by the CE level of the terminal, required for the terminal when it is determined that the MBMS service cannot be received.

Abstract: Provided are a method for a terminal controlling uplink power in a rando access channel-less (RACH-less) handover, and an apparatus for supporting same. The method may comprise the steps of: receiving, from a source base station, an RRC connection reconfiguration message including an uplink grant; transmitting, to a target base station using a first transmission power, an RRC connection reconfiguration complete message, on the basis of the uplink grant; receiving, from the target base station, a NACK corresponding to the RRC connection reconfiguration complete message; ramping the first transmission power to a second transmission power; and transmitting the RRC connection reconfiguration complete message using the ramped second transmission power.

Abstract: A method handling a link failure by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of suspending at least one data radio bearer (DRB) upon detecting an occurrence of the link failure; transmitting, to a specific cell, a radio resource control message indicating the occurrence of the link failure; receiving a response message as a response of the radio resource control message from the specific cell; and resuming the at least one suspended DRB.
