D2D D2D communication and Method for frequency resource allocation based on location using the same

摘要

The present invention relates to a D 2D communication system and a location-based frequency resource allocation method using the same. A method for allocating frequency resources in a D-2D communication system, the method comprising the steps of: acquiring location information and rate information of a plurality of terminals in a cell and searching for a candidate terminal; Grouping the cellular group and the D 2D group into a D 2D group of the cellular group and the D 2D group of the cellular group and the D 2D group, And setting the frequency resources to be shared using the candidate sequence of the candidate group of the cellular group and the candidate group of the candidate group of the D 2D group. As described above, according to the present invention, by allocating resources to the D 2D terminal using the position information and the transmission rate information, it is possible to reduce the interference caused by the terminal of the D 2D (-) in the downlink communication, Can be reduced, and the performance of the system can be improved.
