Abstract: In the situation of 5G platoon communications, the Platoon Leader Vehicle (PLV) utilizes group casting to transmit control messages to Platoon Member Vehicles (PMVs). Due to the restricted transmission power for groupcasting, it may be necessary to select one PMV as the Platoon Relay Vehicle (PRV) to handle re-groupcasting PLV's messages. To improve the usage of limited spectrum resources, resource sharing can be implemented to enhance spectrum efficiency within the platoon. This study proposes a resource allocation method, which is called Resource Sharing for Platoon Groupcasting (RSPG), for platoon's group casting based on transmission reliability. RSPG employs the tripartite matching to allocate a subchannel to either a PLV or PRV, that shares the assigned subchannel with the corresponding individual entity (IE), which does not belong to any platoon. The simulation results demonstrate that the proposed method outperforms in terms of IEs' QoS satisfaction rate, the number of subchannels allocated to platoons, and overall spectral efficiency.
