江淮机电网3月8日报道 3月7日，3GPP的RAN第75次全体大会在克罗地亚的杜布罗夫尼克召开，这是又一次值得载入全球移动通信史册的“里程碑”式的会议：3GPP决定提前完成5G新空口标准！具体地，新的时间节点是：分别于2017年12月完成、2018年3月冻结非独立5G新空口标准。

3GPP决定提前完成 5G 新空口标准，有利于推动部分运营商（尤其是韩国的运营商）在2019年即可尽早实现5G新空口的大规模试验和部署。（韩国计划于2018年冬奥会期间开通5G试商用网络。）

此外，在5G新空口首个版本的标准化工作中，将把“前向兼容性”作为关键的设计原则。这将支持在频段内引入后续5G标准版本中的全新功能和特性，对于支持那些目前尚未确定的行业及用例并实现万物互联的5G愿景至关重要。

此次会议上，AT&T、NTT DOCOMO、SK电讯、沃达丰、爱立信、Qualcomm Technologies（美国高通）、英国电信、Telstra、韩国电信、英特尔、LG Uplus、KDDI、LG电子、Telia Company、Swisscom、TIM、Etisalat Group、华为、Sprint、vivo、中兴通讯、Deutsche Telekom（德国电信）等23家企业共同提交了要求3GPP加速制定5G新空口标准的提案。

另外，此次3GPP RAN第75次全体大会还确定：分别于2018年6月完成、2018年9月冻结独立5G新空口标准。

对于提前完成5G标准新空口标准，20家企业所发表的看法是：

AT&T

“We support both the Standalone and Non-Standalone configurations of 5G New Radio,” said Tom Keathley, senior vice president- wireless network architecture and design, AT&T. “Our focus is on prioritizing important specifications in the standards to bring 5G to market as quickly as possible. In the process of defining any standard, it is normal to make some decisions earlier than others. These accelerated decisions on key components of 5G New Radio standards will allow an earlier start on the development of the infrastructure and devices of tomorrow’s 5G deployments.”

NTT DOCOMO, INC.

Seizo Onoe, executive vice president and chief technology officer, NTT DOCOMO said, “5G is the key enabler to create new business opportunities across industries. DOCOMO plans a commercial launch with Non-Standalone 5G NR by 2020. Acceleration of the standardization schedule will facilitate early implementation of the standard-compliant 5G NR. We will ensure the highly-stable 5G services through large-scale trial activities with a wider range of industry partners.”

SK Telecom, Co. Ltd.

Park  Jin-hyo, senior vice president, head of network technology R&D center, SK Telecom said, “As the demand for 5G commercialization is rapidly increasing, it is crucial to complete globally agreed 5G standardization in time. 3GPP NR is the global 5G standard and we are making continuous efforts to accelerate 3GPP NR standardization with partners.”

Vodafone Group

Luke Ibbetson, head of research and development and strategy, Vodafone Group, said, “Standardisation of the New Radio interface will be critical to the successful development of 5G over the coming years. As the industry starts to design and test a new generation of services and applications, a common global standard for the underlying mobile technology will allow innovation to flourish and help us achieve economies of scale.”

Ericsson

Arun Bansal, senior vice president and head of business unit network products, says, “The faster we commercialize 5G based on 3GPP specifications, the faster we will realize its benefits for the entire industry. We are thrilled to participate in this initiative to accelerate the 5G ecosystem and commercial deployment.”

Qualcomm Technologies, Inc.

Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT said, “5G NR technologies will be critical to meet the ever-increasing connectivity requirements for emerging mobile broadband experiences such as virtual reality, augmented reality and connected cloud computing, and we are already seeing the need to bring these technologies to devices globally sooner rather than later. There is great value in accelerating the timeline to commercialization, while maintaining the global scale through the proper standardization process in 3GPP.”

针对“23家企业于MWC 2017在巴塞罗那宣布将共同支持加速5G新空口（5G NR）的标准化进程”，2017年2月28日，西班牙电信的CTO（首席技术官）Enrique Blanco认为，加速5G新空口标准制定进程本身就是个大错误。

那么，西班牙电信CTO为什么认为加速5G新空口标准制定进程本身就是个大错误呢？西班牙电信首席技术官Enrique Blanco先生在MWC 2017的报告中提到：移动通信网络演进必须解决一些关键的挑战性问题，现有部署模式（增加频谱、增加基础设施）已经无法实现可持续发展。5G应该要考虑成本问题、经济可持续性问题；5G带来诸多新的技术创新，是无线技术发展的又一步。但5G的4大应用场景均面临着很大的挑战，西班牙电信正积极为5G的发展做贡献；NB-IoT及LTE-M可解决目前物联网通信所遇到的诸多显著问题。目前，西班牙电信已经准备好部署IoT物联网。MWC 2017，西班牙电信和爱立信联合展示把5G应用于远程驾驶（使用15 GHz频段）。

结论是：5G的可靠性、高速率、低延迟均满足5G远程驾驶的需求。

延迟低于30毫秒：5G空口2毫秒延迟+传输2毫秒延迟+视频编码器的延迟。大的数据容量：1个5G基站可满足高达50辆汽车的相关需求。频带宽：14.5-15.35 GHz频段，共850 MHz带宽，采取TDD双工制式。大规模天线技术：MU-MIMO（多用户MIMO）。
