Device-to-Device (D2D) communications as an underlay to future 5G networks is being considered as a suitable platform for vehicular communication. Key in this regard is intelligent Radio Resource Management (RRM), which needs to provision adequate quality of service, in terms of the reliability and latency of vehicular transmissions. The classical approach building upon Channel State Information (CSI) is assumed to have high management overhead due to the acquisition of the said information. Hence, alternative RRM schemes, which rely on, e.g., location information, have also emerged. Such schemes, however, are more conservative in regards to the reuse of radio resources and have lower spectral efficiency. In this paper, we compare the performance of two RRM schemes for vehicular D2D underlay networks - a CSI-based one and a location-based one, in terms of their required measurement overhead, with implications to general schemes of the respective class.
