Abstract: A method for a user equipment (UE) in a wireless communication system includes monitoring a physical channel carrying downlink control information (DCI); and receiving, based on the DCI, downlink data in an unlicensed band cell (Ucell). Further, the downlink data is received in a 1st subframe of a downlink transmission burst, based on being configured to monitor the physical channel on the Ucell, the downlink data is received starting in one of a partial subframe or a normal subframe in the 1st subframe, and the partial subframe is smaller than the normal subframe.

Abstract: Multiple short transmission time intervals (TTIs), each of which is shorter than 1 ms, may be configured in a subframe. A user equipment (UE) may transmit a demodulation reference signal (DM-RS) which is shared among different UEs to an eNodeB (eNB). In this case, the DM-RS may be transmitted in a reference TTI, which is one short TTI among the multiple short TTIs, and the reference TTI may be indicated by downlink control information (DCI) received from the eNB. Alternatively, a UE may transmit the DM-RS which is shared among different short TTIs to the eNB.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.

Abstract: Provided are method and device for transmitting/receiving a downlink signal. A user equipment-specific reference signal (UE-RS) can be transmitted to a user equipment. A downlink control channel and a downlink data channel for the user equipment can share the UE-RS. Antenna port information about a transmission antenna port of the downlink control channel and/or a transmission antenna port of the downlink data channel is provided to the user equipment. The user equipment receives UE-RS(s) corresponding to the antenna port information and thus receives the downlink control channel and the downlink data channel.

Abstract: According to the present invention, a base station transmits zero-power information with respect to a downlink control channel, sets some of downlink control channel candidates in a slot at zero-power in accordance with the zero-power information, and transmits the downlink control channel via the downlink control channel candidates User equipment receives the zero-power information with respect to the downlink control channel and receives the downlink control channel via the downlink control channel candidates in the slot. The user equipment detects the downlink control channel by assuming, on the basis of the zero-power information, that the some of downlink control channel candidates are zero-power.
