Abstract: The present invention provides a method and a device for transmitting or receiving channel state information (CSI). According to the present invention, when a user equipment can be set with one or more CSI processes per serving cell, a CSI request field included in downlink control information for a specific serving cell indicates at least whether a non-periodic CSI report triggered by the CSI request field is triggered for a set of CSI process(es) set by a higher layer from among the CSI process(es) for the one serving cell.

Abstract: The present invention relates to a method for transmitting and receiving an uplink signal for low-cost machine-type communication (MTC) used in a wireless communication system, and the apparatuses for supporting same. The base station of the present invention sets a maximum number of RBs capable of being allocated to the MTC device to be smaller than the total number of RBs in a system band supported by the base station. The MTC device of the present invention transmits an uplink signal through a physical uplink shared channel (PUSCH) on the basis of the maximum number of RBs capable of being allocated to the MTC device.

Abstract: A method for measuring a channel in a wireless communication system is provided. A terminal receives a first reference signal from a primary cell. The terminal receives a second reference signal from a secondary cell corresponding to the primary cell. The terminal measures a channel for the secondary cell on the basis of the second reference signal. A subframe in which the second reference signal is received is signaled from the primary cell.

Abstract: The present invention relates to a new type of carrier wave having a different configuration from existing carrier waves. The new type of carrier wave is detected by using at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). When the new type of carrier wave is formed for detection by using only one of the PSS or the SSS, or by using both of the PSS and SSS, the new type of carrier wave includes PSS and SSS transmissions which are different from existing PSS and SSS transmissions.
