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.

Abstract: A method by which a terminal performs cell measurement by selectively using reference signals (RSs) is provided. The terminal receives, from a network, a common RS (CRS) measurement configuration and a discovery RS (DRS) measurement configuration with respect to a frequency to be measured. If the network has configured a physical cell ID (PCID) list for CRS-based DRS measurement with respect to the frequency to be measured, DRS measurement is performed on cells included in the PCID list, and CRS measurement is performed on cells not included in the PCID list. If the network has not configured the PCID list for CRS-based DRS measurement with respect to the frequency to be measured, DRS measurement is performed on all cells belonging to the frequency to be measured.

Abstract: A method and apparatus for determining a measurement period in a wireless communication system is provided. A user equipment (UE) sets start of the measurement period to one of beginning of a period of a broadcast/multicast control channel or beginning of a scheduling period for the broadcast/multicast channel, which is one of a multicast control channel (MCCH) modification period, a MCCH repetition period, a broadcast control channel (BCCH) modification period, or a multicast channel (MCH) scheduling period (MSP). The UE performs, at a radio link control (RLC) layer or a media access control (MAC) layer, measurement from the start of the measurement period.

Abstract: A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. Upon receiving a MBMS-MDT configuration from a network, a user equipment (UE) selects a subset of multicast broadcast single frequency network (MBSFN) areas among multipleMBSFN areas providing interested MBMS services, and performs MBMS-MDT only for the selected subset of MBSFN areas. The subset of MBSFN areas may be selected based on priorities of the multiple MBSFN areas.

Abstract translation: 提供感兴趣的MBMS服务的MBSFN区域，并且仅针对所选择的MBSFN区域的子集执行MBMS-MDT。 可以基于多个MBSFN区域的优先级来选择MBSFN区域的子集。
