Abstract: A method for receiving a signal by a user equipment (UE) in a wireless communication system is discussed. The method includes receiving, from a base station (BS), control information; and receiving, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information. Further, in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and the second time resource is smaller than the first time resource.

Abstract: This specification provides a method of receiving system information in a wireless communication system supporting a TDD narrowband. More specifically, the method performed by a user equipment includes receiving, from a base station, first system information on an anchor carrier, the first system information includes first information indicating whether a carrier used for second system information is an anchor carrier or a non-anchor carrier and second information on a location of the non-anchor carrier used for the second system information, and receiving, from the base station, the second system information on the non-anchor carrier based on the first system information. Accordingly, an SIB1-NB is transmitted and received even on a non-anchor carrier.
