Enhanced SB-SPS Scheme to Mitigate Half Duplex Problem for Relay Transmission in Vehicle Platooning
In vehicle platooning, relay transmission using sidelink communications, specified by the C-V2X (Cellular Vehicle-to-Everything) standard is considered as a means of information exchange. The autonomous resource management scheme, SB-SPS (Sensing Based Semi Persistent Scheduling), has been standardized for sidelink communications. However, a half duplex problem, one of major problems in the SB-SPS, is not sufficiently resolved for the relay transmission in vehicle platooning. This work proposes an enhanced resource management scheme to mitigate half duplex problem in vehicle platooning employing the SB-SPS scheme. The performance evaluation through computer simulation demonstrates the effectiveness of the proposed scheme.
