Abstract: A resource scheduling method for direct device to device communications in a communication system according to the present invention comprises the following steps: selecting a mobile communication terminal to communicating with a base station for each channel dividing mobile communication resources which the base station occupies; calculating a signal to interference noise ratio of the mobile communication terminal by assuming that each terminal pair for direct communications between the selected mobile communication terminal and the terminal located within the service coverage of the base station is allocated to each channel; comparing the signal to interference noise ratio of the mobile communication terminal calculated for each channel with a first threshold and determining the terminal pairs whose signal to interference noise ratios for each channel are greater than the first threshold as candidate members of a combination sharing the relevant channel; and determining whether the relevant channel is allocated to each candidate member of the combination determined for each channel. [Reference numerals] (300) Select a first combination consisting of the entire members of the combination corresponding to a relevant channel;(305) Select a first D2D pair having a maximum SINR among the members of the first combination;(310) Calculate an SINR in terms of a mobile communication terminal if the channel corresponding to the first combination is additionally allocated to the first D2Dpair;(315) If the channel corresponding to the first combination is additionally allocated to the first D2D pair, the SINR in terms of the mobile communication terminal is greater than a first threshold?;(320) Determine not to additionally allocate the channel corresponding to the first combination to the first D2D pair;(325) Assume that the channel corresponding to the first combination is additionally allocated to the first D2D, and calculate an SINR in terms of the D2D pairs to which the channel is already allocated;(330) Is each of SINRs in terms of the first D2D pair and in terms of the D2D pair to which the channel corresponding to the first combination including the first D2D pair is allocated greater than a second threshold?;(335) Delete the first D2D pair from the candidate members of the first combination;(340) Allocate a unit resource of the first combination to the first D2D pair;(345) Does a candidate member whose resource allocation is not determined exist among the candidate members of the first combination?;(AA) Start;(BB,DD,FF,HH) No;(CC,EE,GG) Yes
