  The reliance on wireless network architectures for applications demanding
high reliability and fault tolerance is growing. These architectures heavily
depend on wireless channels, making them susceptible to impairments and
blockages. Ensuring functionality, particularly for safety-critical
applications, demands robust countermeasures at the physical layer. In
response, this work proposes the utilization of a dynamic Rate Splitting (RS)
grouping approach as a resilience mechanism during blockages. RS effectively
manages interference within networks but faces challenges during outages and
blockages, where system performance can deteriorate due to the lowest decoding
rate dictating the common rate and increased interference from fewer available
channel links. As a strategic countermeasure, RS is leveraged to mitigate the
impact of blockages, maintaining system efficiency and performance amidst
disruptions. In fact, the introduction of new RS groups enables the exploration
of novel solutions to the resource allocation problem, potentially
outperforming those adopted before the occurrence of a blockage. As it turns
out, by employing the dynamic RS grouping, the network exhibits an antifragile
recovery response, showcasing the network's ability to not only recover from
disruptions but also surpass its initial performance.
