5g technology R & D test starts and its candidate spectrum has made progress. According to the news on August 18, according to the overall plan of China's 5g technology R & D test, it has entered the second phase of 5g technology R & D test. At this stage, 5g prototype product tests will be carried out on a unified planning, frequency and test platform, and the prices of all DuPont tmzytel nylon products will be raised worldwide. Up to now, Huawei and ZTE have basically completed the second stage of testing, Ericsson and Nokia will start testing, and Datang and Samsung will start testing as planned. At the same time, in this phase of testing, German, Rhode, Lianyi, Spreadtrum and MTK chip/instrument manufacturers were also introduced to realize the physical layer interworking between instruments and system equipment. China's 5g work has turned to standardization and technical testing in an all-round way

China's 5g work has turned to standardization and technical testing in an all-round way

on January 7, 2016, the Ministry of industry and information technology held the "5g technology R & D test" kick-off meeting in Beijing, which means that China's 5g technology test has been fully launched. According to the plan, China's 5g technology R & D test will be carried out during the year, which is divided into three stages: key technology verification, technical scheme verification and system scheme verification. Up to now, China has completed the first phase of 5g technology R & D test, and seven enterprises including Huawei, ZTE, Ericsson, Datang Telecom, Nokia Shanghai Bell, Samsung and Intel have participated in this phase of test. The test completed 7 key wireless technologies including large-scale antenna, new multiple access, new multi carrier and high-frequency communication, as well as 4 key network technologies such as network slicing and mobile edge computing, which fully verified the technical feasibility of the above key technologies in supporting diversified 5g scenarios such as Gbps (gigabit per second) user experience rate, millisecond end-to-end delay and million connections per square kilometer, The confidence of the industry in promoting 5g technology innovation and development has been further enhanced

at a 5g related seminar held yesterday, people from the Ministry of industry and information technology disclosed that in order to seize the development of 5g, the Ministry of industry and information technology actually took the lead in launching the research and development experiment of 5g technology in january2016. In September 2016, the first phase of key tests had been successfully completed

review the progress of global 5g work. In july2016, the US FCC officially divided 28ghz and other high-frequency resources, with a total bandwidth of 10.85ghz, including 3.85ghz licensed spectrum and 7GHz unlicensed spectrum; In july2017, the US government announced that it would invest US $400million to support 5g wireless technology research and development and network speed measurement, and planned to build test platforms in four cities. The US operator Verizon established the Verizon 5g technology alliance as early as 2015, and released a series of v5g technical specifications ahead of 3GPP in 2016, hoping to guide the standardization of 3GPP 5g through v5g specifications

in September 2016, the EU released the 5g action plan, which defined the EU's plans to promote 5g frequency planning, standardization, technical testing, commercial deployment, vertical industry application promotion, capital investment and international cooperation from 2016 to 2025

in February 2016, some US, Japanese and Korean operators (KT, SKT, Verizon and DoCoMo) united with major foreign equipment and chip enterprises to establish 5g open test specification Alliance (otsA)

according to the 5g standard acceleration schedule determined by 3GPP, it is determined that the new 5g air interface standard of the independent group will be completed in december2017, and the ASN will be completed in march2018 1; The independent group 5g new air interface standard was completed in June, 2018, and Asn was completed in September, 2018 1; In september2019, the three scenarios of embB, mmtc and urllc will be supported to meet all ITU technical requirements. At present, 5g has entered a critical period of standard development, and all countries have issued relevant 5g test and commercial plans

it is understood that the United States has begun to lay out an advanced wireless communication research plan and carry out 5g tests in multiple cities; Japan plans to start 5g technology test in 2017 and commercial in 2020; South Korea also launched the research and development of 5g test platform in 2016, and realized pre commercialization in early 2018; EU will launch 5g test in 2018 and realize 5g service vertical industry in 2020; China has started 5g technology research and development test, and will start 5g network commercial in 2020

according to Dr. weikejun, the deputy leader of the wireless technology working group of imt-2020 (5g) promotion group, how to ensure the quality of the screen depends on our experimental machine. China's 5g technology research and development test has entered the second stage of testing. In this stage, 5g prototype product testing will be carried out on a unified planning, frequency and testing platform. So far, Huawei and ZTE have basically completed the second phase of the test task. Ericsson and Nokia have started the test. Datang and Samsung will start the test as planned. At the same time, Shide, Roeder, Lianyi, Spreadtrum and MTK chip/instrument manufacturers were also introduced into the test at this stage, realizing the physical layer interworking of instrument month system equipment and promoting the construction of 5g complete industrial chain

"China's 5g work has turned to standardization and technical testing in an all-round way. ITU has launched the 5g technology evaluation research in february2016, and has basically defined the 5g evaluation requirements, including 5 test environments, 14 evaluation indicators, channel models, etc." Dr. weikejun disclosed

5g candidate spectrum has made positive progress

it is reported that the international standardization of 5g key technologies has made achievements. On the one hand, a number of key wireless technology achievements have been incorporated into the 5g new air interface technology scheme, promoting the inclusion of polar code into the 5g standard. Flexible system design ideas and large-scale antenna technology framework have been accepted by 3GPP. In terms of new multiple access technology, Huawei and ZTE are expected to be fully put into operation in 2017, and Datang and other domestic enterprises have profound technical accumulation. ZTE, as the reporter, is leading the standardization research of 3GPP new multiple access technology. On the other hand, the new 5g network architecture and a number of key network technology achievements were promoted to be incorporated into the 3GPP network standard. Among them, the service-based 5g new network architecture was adopted as the 5g core 1 at the SA plenary session in June. The main technical parameters of the experimental machine fully comply with the requirements of gb/t6111 and gb/t15560 standards

in terms of 5g candidate spectrum research, according to Dr. Wei Kejun, for low frequencies below 6GHz, MHz has been approved for 5g technology research and development test in 2016, and MHz has been approved for 5g technology research and development test in 2017. The Ministry of industry and information technology also solicited public opinions on "issues related to the use of MHz and MHz frequency bands by the fifth generation international mobile communication system (imt-2020)"; For high frequencies above 6GHz, the Ministry of industry and information technology has 5GHz and Two 5GHz frequencies were sent to the public to solicit opinions on planning the frequency of the fifth generation international mobile communication system (5g) in the millimeter wave band, which was approved for 5g technology research and development test in 2017
