Abstract: The present invention provides a method for defining, and for transmitting, a new uplink reference signal and devices supporting the method. In one embodiment of the present invention, a method in which a terminal transmits a millimetre wave reference signal (mW-RS) in a millimetre-wave (mmWave)-supporting wireless access system comprises the steps of: receiving a downlink reference signal in a predetermined number of sub-frames, and measuring two or more received power levels; determining whether to transmit an mW-RS, based on the value(s) of the difference(s) between the two or more received power levels; and transmitting the mW-RS if it has been decided to transmit an mW-RS. Here, the mW-RS is transmitted in order to measure whether the state of a wireless channel has transitioned between an LoS (Light of Sight) state and a NLoS (Non-LoS) state.

Abstract: A method is provided or receiving a downlink control information (DCI) from a base station (BS) by a user equipment (UE) in a wireless communication system. The UE monitors a plurality of Physical Downlink Control Channel (PDCCH) candidates having a cyclic redundancy check (CRC) scrambled by a cell radio network temporary identifier (C-RNTI) and having a same payload size in a common search space and a UE-specific search space on a primary cell to receive the DCI from the BS. The common search space and the UE-specific search space are overlapped. If the UE is configured with a carrier indicator field (CIF), determining, by the UE, that only a PDCCH in the common search space is transmitted by the BS from among the plurality of PDCCH candidates. The UE receives a Physical Downlink Shared Channel (PDSCH) corresponding to the PDCCH in the common search space.
