Fifth-generation (5G) mobile networks are expected to support vast numbers of connected devices and device-to-device (D2D) communication is expected to play a key role in 5G mobile networks. This paper studies the optimization problem of resource allocation that provides rate guarantee by fewest resource blocks. To solve it efficiently, we combine several optimization techniques such as relaxation and the block successive upper bound minimization (BSUM) method and derive a closed-form formula for each iteration in BSUM. Simulation results show that our method outperforms existing algorithms.
