“…Appendix C shows the analysis for the conditional statistics of γ SINR,j , conditioned on the values of |M co,j | and | N j |, which results in (31) and its special case in (47). Now, using the findings in Section III, the unconditional statistics of γ SINR,j can be expressed in a similar form to (27), but with the conditional statistics of γ SINR,j in (31) replace that of γ SINR,j therein.…”

This paper studies imperfect underlay device-to-device (D2D) association in spectrumshared cellular networks. It addresses important system and design interference constraints, processing load limitations and transmit power constraints at D2D terminals. The paper proposes decentralized schemes for D2D communication between D2D terminals when downlink channel resources can be reused in the D2D network. The D2D transmitters are characterized considering their processing load limitation and allocated transmit power constraints. Moreover, the downlink channels that can be reused in the D2D network are quantified while meeting interference constraints imposed by the primary cellular network. Two schemes to identify reusable channels, which vary in terms of their efficiency, communication overhead requirement and implementation complexity, are described. Moreover, two D2D association schemes, namely the simultaneous and sequential D2D associations, are proposed and both aim to concurrently maximize the desired link quality and minimize the effect of interference effect at D2D receivers. Generalized analytical results that are applicable for various imperfect association scenarios are presented. The findings are applicable for any D2D channel models and performance metrics. They provide insights into various imperfect underlay D2D association scenarios under the practical system and design constraints.

“…Herein, the D2D service is adaptively managed such that the served device by the BS attempts to first meet its required QoS, and then it can utilize the remaining unused spectrum bands (channels) to serve other active device(s), which can not be served by BS, through direct D2D link(s). Capitalizing on the findings in [11], which investigated the impact of user identities and their access conditions in the context of closed small-cell networks, and the improved interference-free resource allocation proposals for coordinated multiuser open-access small cells in [12], various operational and design aspects for a suitable D2D cooperation path that can meet specific design targets at the served device are then developed and quantified.…”

This paper proposes new approaches for underlay device-to-device (D2D) communication in spectrum-shared heterogeneous cellular networks. It considers devices that share downlink resources and have an enabled D2D feature to improve coverage. The mode of operation classifies devices according to their experienced base station (BS) coverage, potential to be served by BS, ability of BS to meet their quality of service (QoS), and their downlink resources occupancy. The initiation of D2D cooperation is conditioned on proposed provisional access by an active device, wherein its serving BS attempts to meet its QoS using as low number of spectrum channels as possible, while treating remaining channels for feasible D2D cooperation. Detailed formulations for the mode of operation and a proposed D2D path allocation scheme are presented under perfect and imperfect operation scenarios. The developed results are generally applicable for any performance metric and network model.
