In Release 14, 3GPP completed a first version of cellular\nvehicle--to--everything (C-V2X) communications wherein two modalities were\nintroduced. One of these schemes, known as \mode-3, requires support\nfrom eNodeBs in order to realize subchannel scheduling. This paper discusses a\ngraph theoretical approach for semi-persistent scheduling (SPS) in\n\mode-3 harnessing a sensing mechanism whereby vehicles can monitor\nsignal--to--interference--plus--noise ratio (SINR) levels across sidelink\nsubchannels. eNodeBs request such measurements from vehicles and utilize them\nto accomplish suitable subchannel assignments. However, since SINR\nvalues---herein also referred to as side information---span a wide range,\nquantization is required. We conclude that 3 bits per vehicle every 100 ms can\nprovide sufficient granularity to maintain appropriate performance without\nsevere degradation. Furthermore, the proposed algorithm is compared against\npseudo-random and greedy SPS algorithms.\n
