Techniques, schemes, designs, systems and methods pertaining to HARQ and ARQ design for URLLC in mobile communications are described. A processor of a first apparatus of a mobile network performs a first transmission to a second apparatus of the mobile network in support of ultra-reliablelow-latency communications (URLLC) with a first amount of redundancy. The processor determines whether a predefined condition is met. Responsive to a determination that the predefined condition is met, the processor performs a second transmission to the second apparatus in support of the URLLC with a second amount of redundancy greater than the first amount of redundancy. The processor also multiplexes URLLC traffic and enhanced Mobile Broadband (eMBB) traffic in transmissions to the second apparatus.
