论文摘要
在本文中，我们考虑在机器类型通信（MTC）中共存两种不同类型的设备，即类型1和2型设备，其中1型设备需要短期延迟延迟的低延迟需求，而2型2设备则延迟容忍。对于短期访问延迟，我们研究了一组序言分为两个子集以支持两种不同类型的设备时，我们研究了在序言传输中快速重试的使用。使用Foster-Lyapunov标准来得出稳定性条件，以到达率，前序数量和1型设备数量来得出。我们还提出了一种自适应算法，该算法在稳定条件下动态决定了1型设备的最小序列数量。
In this paper, we consider co-existing two different types of devices in machine-type communication (MTC), namely type-1 and type-2 devices, where type-1 devices need short access delay for low-latency requirements, while type-2 devices are delay-tolerant. For short access delay, we study the use of fast retrial in preamble transmissions when a group of preambles is divided into two subsets to support two different types of devices. Stability conditions are derived using Foster-Lyapunov criteria in terms of arrival rates, the number of preambles, and the number of type-1 devices. We also propose an adaptive algorithm that dynamically decides the minimum number of preambles for type- 1 devices under stability conditions.
