1. A method of controlling transmission and reception of a signal, which is controlled by a user equipment in a situation in which simultaneous transmission and reception is restricted in a plurality of cells in a wireless communication system, the method comprising:configuring an TDD (time division duplex) PCell (primary cell) and an TDD SCell (secondary cell); and
if transmission direction of the TDD PCell and transmission direction of the TDD SCell are different from each other in a subframe, restricting signal transmission and reception on the TDD SCell of the subframe,
wherein if the TDD SCell is not an eIMTA (enhanced interference mitigation and traffic adaptation) cell, the restricting signal transmission and reception on the TDD SCell of the subframe is performed based on a first UL-DL (uplink-downlink) configuration indicated by an SIB (system information block), and
wherein if the TDD SCell corresponds to the eIMTA cell, a first reference UL-DL configuration used for HARQ-ACK (hybrid ARQ acknowledgement) transmission and a second reference UL-DL configuration used for PUSCH (physical uplink shared channel) transmission are further configured for the TDD SCell by an RRC (radio resource control) signaling and a second UL-DL configuration used for UL-DL reconfiguration is further indicated for the TDD SCell by a PDCCH (physical downlink control channel), and the restricting signal transmission and reception on the TDD SCell of the subframe is performed based on the second UL-DL configuration among the first and second UL-DL configurations, and the first and second reference UL-DL configurations.
