摘要翻译：
未来的移动网络不仅要提高移动宽带(MBB)链路的传统链路质量和数据速率，而且要开发新的控制信道来满足时延敏感的使用情况。特别是，对于许多物联网（IoT）用户来说，对超可靠低延迟通信(URLLC)的需求得到了极大的强调。在本文中，我们提出了一种新的扩频波形设计，我们提出了控制信号的传输，以建立URLLC通信。这些控制信号在属于网络中的MBB通信的频谱资源上传输，但以对这些数据信道影响最小的水平传输。所提出的波形虽然是直接序列扩频(DSSS)技术，但其设计是为了利用OFDM宽带通信在网络中可用的符号同步。显然，这允许与网络的其他部分进行简单的同步。所提出的DSSS方法可以在每个OFDM时间帧内传输单个比特和多个比特，并且可以同时服务于多个用户设备(UE)节点。

英文摘要：
Future mobile networks not only envision enhancing the traditional link quality and data rates of mobile broad band (MBB) links, but also development of new control channels to meet the requirements of delay sensitive use cases. In particular, the need for ultra-reliable low-latency communications (URLLC) for many internet of things (IoT) users is greatly emphasized. In this paper, we present a novel spread spectrum waveform design that we propose for transmission of control signals to establish URLLC communications. These control signals are transmitted over the spectral resources that belong to the MBB communications in the network, but at a level that minimally affects these data channels. The proposed waveform, although a direct sequence spread spectrum (DSSS) technique, is designed to take advantage of symbol synchronization available to the OFDM broad band communications in the network. This, clearly, allows simple synchronization with the rest of the network. The proposed DSSS method can transmit single and multiple bits within each OFDM time frame and can serve many user equipment (UE) nodes simultaneously.
