Cellular networks that are traditionally designed for human-type communication (HTC) have the potential to provide cost effective connectivity to machine-type communication (MTC). However, MTC is characterized by unprecedented traffic in cellular networks, thus posing a challenge to its successful incorporation. In this work, we propose a unified framework for amicable coexistence of MTC and HTC. We consider a heterogeneous network where machine-type devices coexist with enhanced mobile broadband (eMBB) devices and propose transceiver techniques that promote efficient signal recovery from these devices. For this, we present an eMBB pilot and MTC data generation strategy that facilitates joint coherent decoding of eMBB data and non-coherent decoding of MTC data. Furthermore, we assess the feasibility of coexistence using receiver operating characteristics, outage probability, and normalized mean square error (NMSE). Our numerical results reveal that a harmonious coexistence of the heterogeneous services can be achieved with properly configured average signal-to-noise ratios and pilot length.

异构网络的联合相干和非相干检测和解码技术

传统上为人类通信 (HTC) 设计的蜂窝网络有可能为机器通信 (MTC) 提供具有成本效益的连接。然而，MTC 的特点是蜂窝网络中的流量空前，因此对其成功整合提出了挑战。在这项工作中，我们提出了一个 MTC 和 HTC 友好共存的统一框架。我们考虑了一个异构网络，其中机器类型的设备与增强型移动宽带 (eMBB) 设备共存，并提出了促进从这些设备进行有效信号恢复的收发器技术。为此，我们提出了一种 eMBB 导频和 MTC 数据生成策略，该策略有助于 eMBB 数据的联合相干解码和 MTC 数据的非相干解码。此外，我们使用接收器操作特性、中断概率和归一化均方误差 (NMSE) 来评估共存的可行性。我们的数值结果表明，通过正确配置平均信噪比和导频长度，可以实现异构服务的和谐共存。
