"allows up to 1 million IoT devices/ square km sporadically send small data bursts... grant-free communication allows devices to send data without prior authorization, reducing processing/ power consumption in end devices, scheduling operations in base stations... data collision risk overcome using analysis systems with randomly distributed elements... interference cancellation improved base station throughput up to 20%, most effective for devices at intermediate distances... fairness/ throughput trade-off"
