In this paper, we consider co-existing two different types of devices in\nmachine-type communication (MTC), namely type-1 and type-2 devices, where\ntype-1 devices need short access delay for low-latency requirements, while\ntype-2 devices are delay-tolerant. For short access delay, we study the use of\nfast retrial in preamble transmissions when a group of preambles is divided\ninto two subsets to support two different types of devices. Stability\nconditions are derived using Foster-Lyapunov criteria in terms of arrival\nrates, the number of preambles, and the number of type-1 devices. We also\npropose an adaptive algorithm that dynamically decides the minimum number of\npreambles for type- 1 devices under stability conditions.\n
