Reducing EMF emissions in ultra-reliable low-latency communications with HARQ

Using HARQ is an efficient mean of adding diversity to communications systems without using unnecessary resources, and when properly tuned, it can be beneficial even for URLLC applications. We have shown how properly designing the scheme can lead to important reductions in the maximum EMF radiation being output by the communication system. In the context of URLLC, several suboptimal aspects of HARQ have to be improved and fine-tuned with latency in mind. However, even in those cases, clever engineering and design can overcome possible added latencies and harvest the efficient resource usage of HARQ. This efficient use of resources is relevant as it enables devices to communicate using less energy and therefore reduces the EMF emission, which is particularly relevant when considering the massive scale of deployments foreseen for the near future.
