Vehicle-To-Everything Downlink and Uplink Communication Using Multi-Carrier Rate-Splitting
Résumé
To highlight the potential of RSMA and multicarrier (MC) techniques in vehicle-to-everything (V2X) communication, we propose and present a two-way communication MC-RSMA V2X communication system that supports a large number of equipments (UEs) and promotes the dual function of sidelink and cellular communication. We employ k-mean clustering for vehicle grouping and a suboptimal sub-carrier allocation with naive equal time and optimal precoder design for data transfer. To confirm the efficacy of the proposed system model, we compare the MC-RSMA solution against an MC-SDMA benchmark, using sum-rate as the performance metric. From the simulation results, the proposed system demonstrates significant improvements over the two multi-access technique benchmarks.
