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 apparatus for transmitting uplink data. Particularly, a method for transmitting uplink data in a wireless communication system, the method includes transmitting, by a user equipment, a scheduling request to a base station, and transmitting, by the user equipment, uplink data through a contention-based physical uplink shared channel (PUSCH) resource block that can transmit the uplink data without a uplink grant of the base station, wherein the scheduling request and the contention-based PUSCH resource block may be transmitted in an identical subframe.

Abstract: Provided are an apparatus and a method for allocating resources in a wireless communication system. In particular, the present invention includes the feature of alternately allocating resources for D2D communication and resources for cellular communication, or allocating resources of a D2D link to not be adjacent to each other. In addition, the present invention prevents interference with the cellular communication and interference with other D2D links by allocating a partial area of the resources allocated for the D2D communication to an area for transmitting a D2D uplink symbol to an eNB, or by adding a GP symbol to a partial area of the resources for the D2D communication. Furthermore, in the case of applying a TDD scheme, the present invention prevents interference with symbols for performing the cellular communication by defining a partial section of a special subframe as a section for transmitting the D2D uplink symbol, or by reflecting a time delay of N OFDM symbol durations. Accordingly, the present invention prevents the D2D communication from causing interference.
