5G即将到来，物联网（IoT）预计将成为5G网络范式的一个突出场景。新兴的5G-IoT场景需要潜在地支持和鼓励大量低成本、低延迟、长电池寿命和高可靠性的设备。物联网预计在未来几年内将有数十亿个同时连接，这将完全改变移动的网络的特征。M2M通信是IoT的主要使能技术，其与5G的机器类型通信（MTC）密切相关。因此，5G的机器类型具有使命关键服务的大量设备之间的通信现在变得非常流行，并被命名为5G-IoT场景。用于5G-IoT场景的信道编码面临着新的挑战，以支持其对延迟，可靠性，可扩展性和能耗的各种要求。因此，FEC码需要支持码长和速率的不同要求，以及具有低解码复杂度的高吞吐量。本文比较了5G-IoT场景的各种候选信道编码方法。极化码被认为是信道编码理论的主要进步，并保证了最佳性能。因此，极化码被认为是5G-IoT场景的有希望的候选者。本文重点研究了极化码在5G-IoT场景中的适用性。
5G is on the horizon and internet of things (IoT) is anticipated as an eminent scenario for the 5G network paradigm. The emerging 5G-IoT scenarios are required to potentially support and encourage the massive number of devices of low cost, low latency, long battery life with high reliability. IoT is envisioned to have billions of simultaneous connections over next few years that will completely change the characteristics of mobile network. M2M communication is prime enabling technology of the IoT which is much related to the 5G’s Machine type Communication (MTC). Therefore, 5G’s machine type Communication between massive numbers of devices with mission critical services is become very popular now days and named as 5G-IoT scenario. Channel Coding for the 5G-IoT scenarios is facing novel challenges as to support its various requirements on latency, reliability, scalability and energy consumption. Hence, an FEC code needs to endorse diverse requirements of code lengths and rates, as well as high throughput with low decoding complexity. This paper compares various candidate channel coding methods for 5G-IoT scenario. Polar code is believed as dominant advancement in channel coding theory and guarantees for apical performance. And hence, polar code is considered as promising candidate for the 5G-IoT scenario. This paper put an emphasis on the suitability of polar codes for 5G-IoT scenario .
