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.

Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.

Abstract: The present invention relates to a method and an apparatus for generating a signal for low latency in a wireless communication system. The method, according to one embodiment of the present invention, for a communication device generating a situation-reporting signal for low latency and transmitting the signal to a base station in a wireless communication system comprises the steps of: generating the situation-reporting signal on the basis of a pre-set, specific situation recognized by the communication device; and transmitting the generated situation-reporting signal to the base station, wherein the situation-reporting signal may be generated so as to have a subcarrier spacing which is a pre-set number of times larger than a subcarrier spacing of a legacy communication system, the pre-set number being an integer.

Abstract: Provided is a method and apparatus for transmitting interference signal information for inter-cell interference cancellation in a wireless communication system. The method for transmitting interference signal information may comprise the steps of: calculating the intensity of a signal on the basis of antenna gain and transmission power for a generated signal; generating probability information on the probability that interference is cancelled when the signal acts as interference; determining interference signal information indicating a feature of the signal when the signal acts as interference, on the basis of the antenna gain, the intensity of the signal, and the probability information; and transmitting the interference signal information to an adjacent cell.
