N2 - This paper studies the pilot placement for power-efficient uplink positioning within future fifth generation (5G) enhanced vehicle to everything (eV2X) networks. The optimal pilot allocation of multicarrier signals may help to fulfil the stringent requirements, in terms of vehicle position accuracy and latency, within vehicular applications, such as autonomous driving. Contiguous and non-contiguous pilot placements in the frequency domain are assessed, by considering the tradeoff between minimum Cramér-Rao bound (CRB) and peak-to-average power ratio (PAPR), among other pilot design criteria. Contiguous placement of pilots with a high separation between subcarriers is a candidate pattern to fulfil the design criteria within future vehicular networks.
