Introduction System (5G) will pave the way for many new capabilities The capabilities of 5G represents a major advancement and features such as ultra-high speed, massive machine over current wireless systems—very high speed of 10 type communications, ultra-reliability, and low latency. Gbps (100 times faster than LTE), up to a 1,000,000 5G is expected to be developed in the years ahead as the connected devices /km2 (100 times the number of devices essential ICT infrastructure supporting the IoT era and supported by LTE), 1 ms delay (one-tenth the delay of Japan’s economic growth. LTE)—which promises to open up all kinds of new Japan’s “Growth Strategy 2018”, approved by the service offerings and applications across many different Cabinet on June 15 this year, highlights the importance of industrial sectors. “rapid dissemination and development of 5G in rural areas 3GPP (3rd Generation Partnership Project) and of Japan”. 5G is required as a powerful engine for growth ITU-R (ITU Radiocommunication Sector) have nationwide, not only in urban areas but also in rural areas stepped up international standardization activities to to activate those region and resolve the problems besetting make 5G a reality by the year 2020.

Preconditions Preconditions for the 5G system were clearly specified 2) Performance Requirements to be Achieved by 5G to define the system and ensure that there were no ITU-R Recommendation M.2412 provides a inconsistencies among the various projects. Here we guideline for evaluating radio interface for IMT-2020 assume that the mobile communications system is the (5G). Within the guideline, test environments are defined 5G system now being investigated by the 3GPP, which is for an evaluation that combines a usage scenario and a expected to be recommended by the ITU-R as the IMT- geographic environment. The evaluation environments 2020 system. are classified as “indoor hot spots”, “dense urban”, “rural”, and “urban wide areas.” The guideline is associated with a 4. Test Environment list of up to 13 requirements: peak data rate, and so on. We use the scenarios, technical performance The key technical performance requirements in the requirements, and required values for the evaluation guideline are a peak data rate of 20 Gbps, a connection environment of 5G as defined by the ITU-R. density of 1,000,000 devices/km2, and a latency of 1 ms. The test environment for the Field Trials is fully 1) Usage Scenarios compliant with these guidelines. The ITU-R drafted the recommendation “IMT 5. Implementation System Vision” (M.2083), which summarizes the basic 5G capabilities and concepts. The Field Trials were conducted in collaboration In this recommendation, three 5G usage scenarios are with major telecom companies and institutions that described: were selected to execute the six projects. Applications (1) eMBB (enhanced Mobile Broadband) were provided by trial partners, and the 5G trials were (2) mMTC (massive Machine Type Communications) conducted not only in the Tokyo metropolitan area, but in (3) URLLC (Ultra Reliable Low Latency rural parts of Japan as well.
