Abstract: A method for a terminal to perform cell reselection procedures in a wireless communication system, and an apparatus supporting the same are provided. The terminal may: receive, from a network, a carrier spreading parameter and re-spreading priority; select a frequency on the basis of a re-spreading test; assign the re-spreading priority to the selected frequency; and perform cell reselection procedures on the basis of the assigned re-spreading priority. The carrier spreading parameter may be a variable for re-spreading of the terminal.

Abstract: Provided is a method for a terminal for measuring the reference signal received quality (RSRQ) of a serving cell.The terminal receives a discovery reference signal (DRS) measurement timing configuration (DMTC) from a network, and on the basis of the received DMTC, the terminal can measure the RSRQ of the serving cell. The serving cell may comprise a small cell supporting a DRS, and the small cell may be present on the same frequency as the serving cell. Furthermore, the RSRQ measurement of the serving cell can only be carried out during a non-DMTC period set in accordance with the DMTC. The non-DMTC period is a period during which a DRS is not transmitted from the small cell.
