Patent ID: 10136442

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.
