“…This is because some bottleneck links may impose too stringent constraints to the overall network. In contrast, much better network throughput can be achieved by selecting a subset of active links in each slot and allocating positive power only to these selected links [3], [4]. By scheduling in time over different subsets of active links, it is possible to achieve individual throughputs (i.e., long-time averaged rates) such that some desired network utility function is maximized.…”

Device-to-device (D2D) communication enables proximity-based applications by exchanging information directly between nearby devices without routing through the cellular infrastructure. In this work, we propose a low-complexity distributed link scheduling and power control mechanism (ITLinQ+) for spectrum sharing in D2D networks, inspired by recent findings showing that power control and treating interference as Gaussian noise achieves rates close to the information-theoretic capacity region of the underlying interference channel under some conditions on the channel strengths. We show that ITLinQ+ substantially improves the average sum-throughput over other state-of-the-art schemes, such as FlashLinQ and the recently proposed ITLinQ. In particular, the new scheme provides large gains in terms of power efficiency.

One of the important processes in device-to-device communication is the discovery of proximate devices. In order to perform precise discovery of devices, the distance information among all the device pairs should be gathered by each device sending a discovery signal in turn and the other devices receiving the signal. However, periodic discovery signal transmission by every device might require too long discovery period or too large resource for discovery. Above all, some discovery information might be lost due to several practical reasons and it may take substantial amount of time to obtain all the necessary information. In this paper, we propose a proximate-device-discovery method using partial discovery information in order to reduce the resource for discovery and support the cases in which some discovery information can be lost. We also discuss discovery probabilities with partial discovery information.※ 본 연구는 지식경제부 및 한국산업기술평가관리원의 산업융합원천기술개발사업(정보통신)의 일환으로 수행되었습니다 (10038765, 스마트 모바일 서비스를 위한 B4G 이동통신기술개발) 주저자：동국대학교 정보통신공학과,

“…Gradually, other major D2D use-cases, like machine-to-machine communications [5], multicasting [6,7], cellular offloading [8], peerto-peer communications [9], and video delivery [10À13] emerged. Qualcomm's FlashLinQ [14] is the first effort to implement D2D communications in cellular networks. In order to create ingenious techniques for peer discovery, link management, and time synchronization in D2D cellular networks, FlashLinQ explores benefits of orthogonal frequency division multiplexing/orthogonal frequency access (OFDM/OFDMA) technologies and distributed scheduling.…”

Device-to-device (D2D) communication facilitates two users in close proximity to communicate directly, bypassing the Evolved Node B (eNB). It provides several advantages like increased spectral efficiency, energy efficiency, decreased transmission delay, and traffic offloading from eNBs. Native support of D2D communications in the emerging fifth generation cellular systems raises significant challenges, like interference, mode selection, resource allocation, and security. Ratification of standards and collaborative research works between industries and academia are now focusing to gradually resolve these challenges. In this paper, we present a novel survey of D2D communications. Our survey provides a new classification of major research works in D2D communications on the basis of frequency and control. Subsequently, major D2D architectures, protocols, and relevant applications are discussed. We also make a detailed review of the analysis techniques and point out open research challenges.
