5G NR in the unlicensed spectrumHao LinZuomin WuChuanfeng HeCong ShiKevin Lin5G NR and Enhancements
Enhancements on MIMO for NRare dedicated to the improvement of MIMO performance in 5G NR. A lot of new items have been introduced in Rel-15, building on the Rel-14 enhancements in LTE, along with the change in the RF antenna array and introduction of Type-II channel state information (CS...
如图3所示,为了满足终端日益增长的速率和容量需求,NR和未来6G通信系统将引入毫米波、太赫兹等高频段以获取更大的频带资源。考虑到频段越高,传播损耗越大,为了实现更好的覆盖,毫米波需运用大规模天线和波束赋性技术,其中,在NR初期版本中,基站独立指示各载波波束,...
5G NR广播多播业务(Multicast/Broadcast Services,MBS)的发展使得多媒体内容(例如共安全和关键任务服务、V2X 应用、IPTV、直播视频、无线软件交付和 IoT 应用等)能够通过广播的传输方式传送到UE,因而用户能够随时随地观看广播电视节目或接收数据推送服务。通常传输数据是以单播形式进行,当用户人数过多时网络就会出现拥塞。
此前在2020年3月,中国广电700MHz频段2×30/40MHz技术提案获3GPP接入网全会采纳并列入5G国际标准,成为全球首个5G低频段(Sub-1GHz)大带宽5G国际标准。去年12月,由中国广电参与的“Enhancements of NR Multicast and Broadcast Services...
Future research in 5G NR is focusing on enhancements such as integrated access and backhaul (IAB), non-terrestrial networks (NTNs), and further optimization of network slicing. Additionally, research is being conducted on extending 5G capabilities to support use cases like holographic communications,...
中国广电参与5G NR组播广播的持续演进立项 12月16日会议中最终确定下的27个项目中包含了课题“Enhancements of NR Multicast and Broadcast Services(WI)”,其由RAN2主导,是基于R16/R17特性演进和增强的R18课题。该课题参与方包括了中国信科下的电信科学技术研究院、中国广电、中国移动、华为、中兴、诺基亚、爱立信等...
Normative standardization for NTN NR and NTN IoT started in Rel 17. Further enhancements, especially focusing on mobility scenarios and throughput enhancement, will come with Rel 18.Rel 19 will address the regenerative payload (i.e., base station functionality embarked in the satellite) according ...
如前所言，中国广电支持支持RAN共享功能的写入，主要考虑了有实际的部署场景和优化需求，认为非常需要提高NR MBS传输的效率。对于支持免费广播/仅接收模式的增强功能“Enhancements for Support of Free-to-Air/receive only mode (pending SA1/SA2 support)”，中国广电表述为是“强烈建议将此功能作为WID中的一个...
