We study energy efficient VUE association problem, which aims to balance the power consumption of VUEs and cellular infrastructure with the help of the selection of the appropriate communication interface. the problem aims to minimize power consumption of the network for Uplink (UL) and Downlink (DL) decoupled UE association scheme, considers switching on/off the Small Base Stations (SBS)s and supports C-V2X link formation either over LTE-Uu conventional cellular radio interface and 5G or over Sidelink (SL), PC5 radio interface. We additionally incorporate realistic power consumption model for BSs, VUEs in UL and Fronthaul (FH) links, centralized controller and Transmit (TX) and Receive (RX) operations of VUEs. Simulation results demonstrate that enabling the selection of communication interface provides decrease in power consumption of the network instead of forcing VUEs to form communication links over LTE-Uu conventional cellular radio interface for varying number of distance thresholds and VUEs.TelecommunicationsConference proceeding287334800006N/A7096
