3、24Acronyms.25Acknowledgments.27Endnotes.28 Extended Reality and 3GPP Evolution 3Executive SummaryExtended Reality(XR)enhances our lived experiences with Augmented Reality(AR),Virtual Reality(VR)and Mixed Reality(MR).It creates either fully virtual,immersive environments or blends those virtual lands

4、capes and features with the“real”world.Its use cases are not limited to consumer applications like gaming,but also include enterprise,institutions,and manufacturing.XR will influence the way people play,work,learn,and interact with each another.VR,but particularly AR,requires significant development

5、 in multiple areas including but not limited to multi-media,artificial intelligence,computing,display systems,and communication to provide experiences that incorporate XR into our daily lives.Low latency,high reliability,lower power consumption and high capacity are key service requirements for the

6、success of XR.5G New Radio(NR)developed by 3rd Generation Partnership Project(3GPP)is designed to support emerging XR uses cases that require such Key Performance Indicators(KPI).While 5G NR benefits XR,potential enhancements for 5G and balanced KPIs require further end-to-end optimizations.This whi
