Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments.

FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application.

As shown in FIG. 1, communication system 100 can include terminal device 110 and network device 120. Network device 120 can communicate with terminal device 110 over an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

It should be understood that the embodiment of the present invention is only exemplified by the communication system 100, but the embodiment of the present invention is not limited thereto. That is, the technical solution of the embodiment of the present invention can be applied to various communication systems, for example, a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a broadband. Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD) , Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, New Radio (NR) or future 5G systems. In addition, the technical solutions in the embodiments of the present application can be applied to various communication systems based on non-orthogonal multiple access technologies, for example, a sparse code multiple access (SCMA) system, and a low-density signature (Low). Density Signature (LDS) system, etc., of course, the SCMA system and the LDS system may also be referred to as other names in the communication field; further, the technical solution of the embodiment of the present application can be applied to multi-carrier using non-orthogonal multiple access technology.

Moreover, a large number of LTEs are deployed below 6 GHz, and there are few spectrums below 6 GHz that can be used for 5G. Therefore, NR must study spectrum applications above 6 GHz, while high-band coverage is limited and signal fading is fast.

Typical applications for URLLC include: industrial automation, power automation, telemedicine operations (surgery), and traffic safety. Typical features of mMTC include: high connection density, small data volume, delay-insensitive service, low cost and long life of the module.

In addition, since the complete 5G NR coverage is difficult to obtain, the network coverage of the embodiment of the present invention may adopt a wide-area Long Term Evolution (LTE) coverage and an NR coverage mode. At the same time, in order to protect the mobile operator's previous investment in LTE, it is further possible to adopt a tight interworking mode of operation between LTE and NR.
