技术领域technical field

本发明涉及通信技术领域，尤其涉及一种终端设备。The present invention relates to the field of communication technologies, and in particular, to a terminal device.

背景技术Background technique

随着经济的发展和社会的进步，消费者对通信技术的发展提出了新的需求，如更高的通信速率，以支持超高清视频的应用；更低的网络延时，满足自动驾驶远程医疗的控制速度需求；更大的连接容量和流量密度，以满足泛在的物联网以及热点区域覆盖的需求。这些需求，基于长期演进LTE网络架构和技术的演进，以及LTE频谱的现状，已经没法满足，因此，第五代移动通信技术(简称5G)应运而生。With the development of economy and the progress of society, consumers have put forward new demands for the development of communication technology, such as higher communication rate to support the application of ultra-high-definition video; lower network delay to meet the requirements of autonomous driving telemedicine control speed requirements; greater connection capacity and traffic density to meet the ubiquitous IoT and hotspot area coverage requirements. These demands cannot be met based on the evolution of the LTE network architecture and technology and the status quo of the LTE spectrum. Therefore, the fifth generation mobile communication technology (5G for short) came into being.

第五代移动通信技术为了满足下行高数据速率的需求，对于6GHz以下的频率范围，规划了3.3GHz-4.2GHz，4.4GHz-5.0GHz两个频率范围的新频段，并引入了100MHz的单载波信道带宽，高阶调制如1024QAM调制技术，以及下行4*4MIMO技术等。同时在未来的5G手机里边，4G LTE将长期存在，将LTE的下行数据传输能力和5G的下行数据传输能力整合起来，将可以为用户提供比单独5G网络更高的数据速率体验。In order to meet the demand for high downlink data rate, the fifth-generation mobile communication technology has planned two new frequency bands of 3.3GHz-4.2GHz and 4.4GHz-5.0GHz for the frequency range below 6GHz, and introduced a 100MHz single carrier Channel bandwidth, high-order modulation such as 1024QAM modulation technology, and downlink 4*4MIMO technology, etc. At the same time, in future 5G mobile phones, 4G LTE will exist for a long time. The integration of LTE's downlink data transmission capability and 5G's downlink data transmission capability will provide users with a higher data rate experience than a single 5G network.

因此，如何针对上述功能的引入进行终端设计，在成本、功耗、印制电路板PCB空间等方面都带来了很大的挑战。Therefore, how to design a terminal for the introduction of the above functions brings great challenges in terms of cost, power consumption, and printed circuit board PCB space.
