- Abstract
- Recently, the 3rd Generation Partnership Project (3GPP) has introduced cellular vehicular-to-everything (C-V2X) standards to support vehicle-to-everything (V2X) communications. In C-V2X, radio resources can be managed either through a central network control or decentralized manner (Mode 4). In Mode 4, each vehicle selects its own resources to transmit V2X messages without any cellular network support. Focusing on Mode 4, we study and discuss the impact of transmission power under varying density of vehicles through simulations. Based on the discussion results, we proposes an adaptive power control algorithm. In our proposed algorithm, each vehicle takes real-time channel sensing information as an input for its transmit power control. Finally, we show that the proposed algorithm outperforms the conventional scheme.
