Abstract: This document discloses a method and an apparatus for transmitting and receiving data in a wireless communication system supporting a specific service. A mobile terminal according to the present invention transmits a preamble and data for the specific service to a base station; and receives feedback information carrying a reception result of the preamble and the data from the base station. Based on the feedback information, the mobile terminal may not re-transmit the preamble and the data to the base station or re-transmit at least one of the preamble or the data to the base station, wherein the preamble and the data are transmitted through a first contention based channel, the first contention based channel is not a dedicated channel for a specific UE.

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: Provided are a method and device for performing channel estimation in a wireless communication system. Specifically, user equipment receives a control channel in the first symbol of a plurality of symbols received for a short TTI (sTTI) set to be shorter than a TTI. The user equipment receives a data channel scheduled by the control channel in the remaining symbols other than the first symbol of the plurality of symbols received in the sTTI. The user equipment receives a user equipment (UE)-specific reference signal having the same frequency resource as a first cell-specific reference signal received in the TTI in the first symbol. The first cell-specific reference signal is received subsequent to the UE-specific reference signal, and the UE-specific reference signal is received in the sTTI. The user equipment decodes the control channel or the data channel using the UE-specific reference signal.
