Abstract: Disclosed herein are a method and an apparatus for transmitting an uplink signal. The method for transmitting an uplink signal includes: transmitting an uplink data in at least one symbol included in a short transmit time interval (sTTI) including 7 symbols or less; and transmitting a demodulation reference signal (DMRS) for the uplink data through an even-numbered subcarrier or an odd-numbered subcarrier in one symbol in which the uplink data is not transmitted, among the symbols included in the sTTI.

Abstract: A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.

Abstract: A communication system configured to send data using an interference alignment scheme is disclosed herein. The disclosed communication system includes an MS and a BS. The disclosed BS sends data using a transmission beamforming matrix that minimizes intra-cell interference. The disclosed MS receives the data using a reception beamforming matrix that minimizes inter-cell interference. The BS sends information about a reference beamforming matrix to the MS, and sends a pilot signal to the MS using the reference beamforming matrix. The MS estimates an effective channel using the reference beamforming matrix, and calculates the intensity of an interference signal from an interference BS.

Abstract: A method of managing a low-duty mode operation is provided by a small base station. The small base station determines a low-duty cycle pattern in which an available interval for data traffic transmission on active air interface and an unavailable interval for transmitting no data traffic are repeated, and provides a terminal with low-duty cycle pattern information. The low-duty cycle pattern information includes a length of the available interval and a start offset indicating a wireless frame at which the low-duty cycle pattern starts.
