A single bidirectional link is used to allow communication between two devices in the device-todevice (D2D) communication system. D2D technology has to implement with the current cellular system. As both users D2D and cellular use the same licensed spectrum for transmission the chances of interferences increases. It is challenging for researchers to find out the proper mechanism to decrease interference and maximize performances. In this paper, we try to survey the challenges and their solutions to enable D2D communication in the cellular network with low interference. Here we describe the peer discover, mode selection process and interference management with power control and resource allocation. Finally, we can say that with proper power control, spectrum slicing and resource allocation we can mitigate co-tier and cross-tier interferences.
