Abstract: Disclosed are a method for performing a cell reselection procedure by a terminal, and an apparatus supporting the same. The method comprises the steps of: measuring a first CE level in a serving cell where the terminal is currently staying; measuring a second CE level in a neighboring cell where an MBMS service of interest is provided; calculating a ranking of the neighboring cell by adding an offset to a quality value measured for the neighboring cell, when the second CE level is higher than or equal to the first CE level; and performing a cell reselection procedure on the basis of the calculated ranking.

Abstract: A method and an apparatus for cell reselection by ranking cells using PLMN offset in unlicensed frequency in a wireless communication system is provided. The method, by a UE, may include measuring a quality of a serving cell and a neighboring cell, receiving a PLMN offset on unlicensed frequency from a network, determining ranking of the serving cell and the neighboring cell based on the PLMN offset and the measured quality, and performing a cell reselection based on the determined ranking.

Abstract: Disclosed are a method for measuring a mobility state of a terminal and an apparatus for supporting same. The method comprises the steps of: receiving, from a current cell, a mobility value related to a previous cell when a terminal moves from the previous cell to the current cell; storing the received mobility value; and measuring the mobility state of the terminal on the basis of the stored mobility value.

Abstract: Disclosed are a method for a terminal not supporting frequency priority-based cell reselection performing a cell reselection procedure in a wireless communication system, and a device supporting same. The method comprises the steps of: determining whether an MBMS service of interest is being provided on a serving cell by a neighboring cell; when it is determined that the MBMS service of interest is being provided by the neighboring cell, measuring the quality of a frequency of interest on which the MBMS service of interest is being provided; and performing a cell reselection procedure for the neighboring cell on the basis of the measured quality.

Abstract: Method and apparatus for a user equipment (UE) supporting dual connectivity (DC) with a master node and a secondary node are disclosed. According to these, the UE receives first configuration information from the master node and second configuration information from the secondary node. The UE applies the first configuration information first. And, the UE transmits a new configuration request message to the secondary node, if the UE cannot apply the second configuration information after applying the first configuration information.

Abstract: A light connection state is different from a substate of a radio resource control connection (RRC) state or the RRC connection state, and is a state which allows free movement of a UE in a plurality of cells without involving a handover process controlled by a network. A terminal in the RRC connection state, which has received a cell radio network temporary identity (C-RNTI) from a first cell, enters the light connection state and then moves to a second cell. The terminal in the light connection state receives, from the second cell, a random access reply including a temporary C-RNTI during a random access process, and replaces the C-RNTI received from the first cell with the temporary C-RNTI.
