Abstract: Provided are a method for discontinuous reception (DRX) in an unlicensed band, and a device using the same. The device is converted from a sleep state to an active state, and attempts downlink synchronization during a synchronization period. If the device does not obtain the downlink synchronization during the synchronization period, downlink data is received in the unlicensed band on the assumption that the modulation order of the downlink data scheduled in the active state is not greater than a specific value.

Abstract: Provided are a method for determining a valid subframe for cell in a non-licensed band in a wireless communication system, and a wireless apparatus using the method. The method comprises: determining whether all orthogonal frequency division multiplexing (OFDM) symbols of the cell are usable; and when all of the OFDM symbols of the subframe are usable, determining whether the subframe is a valid subframe based on whether a channel state information-reference signal (CSI-RS) resource is present in the subframe.
