Abstract: The present application discloses a method for transmitting uplink signals through multiple cells in a wireless communication system. Particularly, the uplink signal transmission method comprises: a step of receiving a first downlink signal at a first timing through a first cell and receiving a second downlink signal at a second timing through a second cell; a step of transmitting a first uplink signal, corresponding to the first downlink signal, through the first cell after a first processing time has elapsed since the first timing; and a step of transmitting a second uplink signal, corresponding to the second downlink signal, through the second cell after a second processing time has elapsed since the second timing, wherein, if the first uplink signal and the second uplink signal are transmitted at the same timing, uplink transmission power is allocated first to the uplink signal corresponding to the downlink signal received at the preceding timing between the first timing and the second timing.

Abstract: The present specification provides a method and UE for receiving configuration usable for a discovery, which can be used in a small cell scenario. In detail, the UE is configured for receiving measurement configuration for a discovery signal, wherein the discovery signal includes CRS, PSS, and SSS. The discovery may further include a channel status information-reference signal (CSI-RS) depending on a configuration of the CSI-RS. The measurement configuration may include at least one set of configuration elements. The UE performs a measurement on the discovery signal based on the received configuration. Further, the UE receives channel status information-reference signal (CSI-RS) configuration including at least one set of CSI-RS configuration elements used for a zero power CSI-RS, wherein the CSI-RS configuration includes at least one set of CSI-RS configuration elements, each set of CSI-RS configuration elements includes CSI-RS interval information and CSI-RS offset information.

Abstract: A method and apparatus for transmitting a physical uplink control channel (PUCCH) in a wireless communication system is provided. A machine-type communication (MTC) user equipment (UE) determines a PUCCH resource in a plurality of subframes. The PUCCH resource is subject to frequency hopping across the plurality of subframes regardless of a number of repetition of PUCCH transmission and a starting subframe of the PUCCH transmission. The UE transmits the PUCCH by using the PUCCH resource to a network.
