Device-to-device (D2D) communication is being heralded as an important part\nof the solution to the capacity problem in future networks, and is expected to\nbe natively supported in 5G. Given the high network complexity and required\nsignalling overhead associated with achieving synchronization in D2D networks,\nit is necessary to study asynchronous D2D communications. In this paper, we\nconsider a scenario whereby asynchronous D2D communication underlays an OFDMA\nmacro-cell in the uplink. Motivated by the superior performance of new\nwaveforms with increased spectral localization in the presence of frequency and\ntime misalignments, we compare the system-level performance of a set-up for\nwhen D2D pairs use either OFDM or FBMC/OQAM. We first demonstrate that\ninter-D2D interference, resulting from misaligned communications, plays a\nsignificant role in clustered D2D topologies. We then demonstrate that the\nresource allocation procedure can be simplified when D2D pairs use FBMC/OQAM,\nsince the high spectral localization of FBMC/OQAM results in negligible\ninter-D2D interference. Specifically, we identify that FBMC/OQAM is best suited\nto scenarios consisting of small, densely populated D2D clusters located near\nthe encompassing cell's edge.\n
