- the 5G usage scenarios shown in FIG. 1 are only exemplary, and the technical features of the present disclosure can be applied to other 5G usage scenarios which are not shown in FIG. 1.
- Three main requirement categories for 5G include (1) a category of enhanced mobile broadband (eMBB), (2) a category of massive machine type communication (mMTC), and (3) a category of ultra-reliable and low latency communications (URLLC).
- eMBB enhanced mobile broadband
- mMTC massive machine type communication
- URLLC ultra-reliable and low latency communications
- Partial use cases may require a plurality of categories for optimization and other use cases may focus only upon one key performance indicator (KPI).
- KPI key performance indicator
- eMBB far surpasses basic mobile Internet access and covers abundant bidirectional work and media and entertainment applications in cloud and augmented reality.
- Data is one of 5G core motive forces and, in a 5G era, a dedicated voice service may not be provided for the first time.
- voice will be simply processed as an application program using data connection provided by a communication system.
- Main causes for increased traffic volume are due to an increase in the size of content and an increase in the number of applications requiring high data transmission rate.
- a streaming service (of audio and video), conversational video, and mobile Internet access will be more widely used as more devices are connected to the Internet.
- Cloud storage and applications are rapidly increasing in a mobile communication platform and may be applied to both work and entertainment.
- the cloud storage is a special use case which accelerates growth of uplink data transmission rate.
- 5G is also used for remote work of cloud. When a tactile interface is used, 5G demands much lower end-to-end latency to maintain user good experience.
- Entertainment for example, cloud gaming and video streaming, is another core element which increases demand for mobile broadband capability. Entertainment is essential for a smartphone and a tablet in any place including high mobility environments such as a train, a vehicle, and an airplane.
- Other use cases are augmented reality for entertainment and information search. In this case, the augmented reality requires very low latency and instantaneous data volume.
- one of the most expected 5G use cases relates a function capable of smoothly connecting embedded sensors in all fields, i.e., mMTC. It is expected that the number of potential Internet-of-things (IoT) devices will reach 204 hundred million up to the year of 2020.
- An industrial IoT is one of categories of performing a main role enabling a smart city, asset tracking, smart utility, agriculture, and security infrastructure through 5G.
- URLLC includes a new service that will change industry through remote control of main infrastructure and an ultra-reliable/available low-latency link such as a self-driving vehicle.
- a level of reliability and latency is essential to control a smart grid, automatize industry, achieve robotics, and control and adjust a drone.
- 5G is a means of providing streaming evaluated as a few hundred megabits per second to gigabits per second and may complement fiber-to-the-home (FTTH) and cable-based broadband (or DOCSIS). Such fast speed is needed to deliver TV in resolution of 4K or more (6K, 8K, and more), as well as virtual reality and augmented reality.
- Virtual reality (VR) and augmented reality (AR) applications include almost immersive sports games.
- a specific application program may require a special network configuration. For example, for VR games, gaming companies need to incorporate a core server into an edge network server of a network operator in order to minimize latency.
- Automotive is expected to be a new important motivated force in 5G together with many use cases for mobile communication for vehicles. For example, entertainment for passengers requires high simultaneous capacity and mobile broadband with high mobility. This is because future users continue to expect connection of high quality regardless of their locations and speeds.
- Another use case of an automotive field is an AR dashboard.
- the AR dashboard causes a driver to identify an object in the dark in addition to an object seen from a front window and displays a distance from the object and a movement of the object by overlapping information talking to the driver.
- a wireless module enables communication between vehicles, information exchange between a vehicle and supporting infrastructure, and information exchange between a vehicle and other connected devices (e.g., devices accompanied by a pedestrian).
- a safety system guides alternative courses of a behavior so that a driver may drive more safely drive, thereby lowering the danger of an accident.
- the next stage will be a remotely controlled or self-driven vehicle. This requires very high reliability and very fast communication between different self-driven vehicles and between a vehicle and infrastructure. In the future, a self-driven vehicle will perform all driving activities and a driver will focus only upon abnormal traffic that the vehicle cannot identify.
- Technical requirements of a self-driven vehicle demand ultra-low latency and ultra-high reliability so that traffic safety is increased to a level that cannot be achieved by human being.
- a smart city and a smart home/building mentioned as a smart society will be embedded in a high-density wireless sensor network.
- a distributed network of an intelligent sensor will identify conditions for costs and energy-efficient maintenance of a city or a home. Similar configurations may be performed for respective households. All of temperature sensors, window and heating controllers, burglar alarms, and home appliances are wirelessly connected. Many of these sensors are typically low in data transmission rate, power, and cost. However, real-time HD video may be demanded by a specific type of device to perform monitoring.
- the smart grid collects information and connects the sensors to each other using digital information and communication technology so as to act according to the collected information. Since this information may include behaviors of a supply company and a consumer, the smart grid may improve distribution of fuels such as electricity by a method having efficiency, reliability, economic feasibility, production sustainability, and automation.
- the smart grid may also be regarded as another sensor network having low latency.
- Mission critical application is one of 5G use scenarios.
- a health part contains many application programs capable of enjoying benefit of mobile communication.
- a communication system may support remote treatment that provides clinical treatment in a faraway place. Remote treatment may aid in reducing a barrier against distance and improve access to medical services that cannot be continuously available in a faraway rural area. Remote treatment is also used to perform important treatment and save lives in an emergency situation.
- the wireless sensor network based on mobile communication may provide remote monitoring and sensors for parameters such as heart rate and blood pressure.
- Wireless and mobile communication gradually becomes important in the field of an industrial application.
- Wiring is high in installation and maintenance cost. Therefore, a possibility of replacing a cable with reconstructible wireless links is an attractive opportunity in many industrial fields.
- it is necessary for wireless connection to be established with latency, reliability, and capacity similar to those of the cable and management of wireless connection needs to be simplified. Low latency and a very low error probability are new requirements when connection to 5G is needed.
- Logistics and freight tracking are important use cases for mobile communication that enables inventory and package tracking anywhere using a location-based information system.
- the use cases of logistics and freight typically demand low data rate but require location information with a wide range and reliability.
