Although centralised-control schemes for device-to-device (D2D) underlay communications can produce satisfactory results by efficiently managing the interference between cellular and D2D transmissions, they can become prohibitively complicated and may require a large amount of feedbacks from devices, because it is important to handle the inter-cell interference as well as the intra-cell interference. Such a burden can be alleviated by a distributed-control mechanism, in which a base station performs the resource management of its cellular devices and each D2D device selects its own resource without a small-scale control of the cellular network. This paper addresses interference issues in distributed-control D2D underlay systems and presents an interference mitigation technique based on frequency spreading, in order to meet the target outage probability. This paper also proposes a simple estimation scheme, which can be used for the mode selection and the determination of D2D transmission parameters. Copyright
