This study investigates relay-assisted mode 1 sidelink multicast transmission for low-latency vehicle-to-everything communications, and proposes a hybrid multiple access approach to accommodate mode 1-mode 2 sidelink traffic.
This study investigated relay-assisted mode 1 sidelink (SL) multicast transmission, which encounters interference from mode 2 SL transmission, for use in low-latency vehicle-to-everything communications. To accommodate mode 1-mode 2 SL traffic, we use the hybrid multiple access (MA) approach, which combines orthogonal MA (OMA) and nonorthogonal MA (NOMA) schemes. We introduce a low-complexity location-based hybrid MA algorithm and its associated relay selection that can be used when SL channel state information is unavailable.
