Addressing Rare Outages in CV2X with Time-Controlled One-shot Resource
Scheduling
Abstract
Cellular Vehicle-to-Everything (C-V2X) has become one of the highest
anticipated technologies for vehicular safety network. In LTE C-V2X
Basic Safety Messages (BSMs) are transmitted on radio resources that are
allocated with a periodic resource reusability. This allocation is based
on a semi persistent sensing-based scheduling scheme (SPS) algorithm.
But, due to this reuse of periodic resources, the possibility of loss of
consecutive packets between the same vehicle pair is significant. This
study dis-cusses different approaches proposed to solve this consecutive
loss problem. Based on this investigation, this article suggests an
efficient One-Shot based solution with a new control parameter, that
performs superior to the state-of-the-art solution that is standardized
in SAE J3161/1 which this article analyzes and shows to have limitation
in case of high-density scenario.
