In this paper, we consider co-existing two different types of devices inmachine-type communication (MTC), namely type-1 and type-2 devices, wheretype-1 devices need short access delay for low-latency requirements, whiletype-2 devices are delay-tolerant. For short access delay, we study the use offast retrial in preamble transmissions when a group of preambles is dividedinto two subsets to support two different types of devices. Stabilityconditions are derived using Foster-Lyapunov criteria in terms of arrivalrates, the number of preambles, and the number of type-1 devices. We alsopropose an adaptive algorithm that dynamically decides the minimum number ofpreambles for type- 1 devices under stability conditions.
