Abstract: A method and apparatus for Radio Link Monitoring for multiple active bandwidth parts in a wireless communication system is provided. A wireless device receives a BWP configuration including information on (i) multiple BWPs, and (ii) a priority for the multiple BWPs. A wireless device activates a first BWP and a second BWP among the multiple BWPs. A wireless device performs RLM procedure only for the first BWP which has been determined as a primary active BWP. A wireless device determines to change the primary active BWP from the first BWP to the second BWP upon detecting a BWP failure for the first BWP. A wireless device performs RLM procedure for the second BWP which is selected as the primary active BWP.

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: A method for performing handover in a wireless communication system and a device therefor are disclosed. Specifically, the method for performing handover by a user equipment (UE) without a wireless local area network (WLAN) termination (WT) change from a source eNodeB (eNB) to a target eNodeB (eNB) in a wireless communication system, the method includes transmitting an end-marker request for requesting retransmission of an end-marker packet to the target eNB when a loss of the end-marker packet is detected after the handover without the WT change is started, and retransmitting the end-marker request or performing a recovery procedure for the end-marker packet when the end-marker packet is not received from the target eNB after the transmitting the end-marker request.
