摘　　要：随着元宇宙的兴起,扩展现实成为产业界重点关注的多媒体应用技术。为了逐步实现扩展现实,需要增强现有无线网络技术。首先介绍了扩展现实业务特点和在3GPP中的标准进展,探索了扩展现实业务对5G-Advanced网络提出的挑战,为了满足扩展现实业务的低功耗和高容量需求,研究了扩展现实业务感知技术、节能增强技术和容量增强技术,通过引入分组数据单元集参数、业务抖动等辅助信息实现业务感知,通过引入非整数周期、非连续接入播放器降低终端功耗,通过支持新缓冲状态表格、增强配置授权提升系统容量,通过仿真评估和性能分析,展示了所提增强技术可以为扩展现实业务提供更好的无线网络支持。With the rise of the metauniverse,extended reality has become the multimedia application technology vigorously promoted by the industry.To realize extended reality,it is necessary to enhance the existing wireless network technology to meet the requirements of extended reality services.Firstly,the characteristics of extended reality technology and standard progress in 3GPP were analyzed.In addition,the challenges posed by extended reality services to the 5G-Advance network were explored.To meet the challenges posed by extended reality services,the XRawareness mechanism,power saving enhancement mechanism,and capacity improvement technologies were investigated.Specifically,based on the packet data unit related parameters,jitter,etc.assistance information,the network can be aware of the XR traffic.In addition,the power consumption can be reduced by introducing the non-integer discontinuous reception mechanism and the playout buffer.And the capacity can be improved by introducing the new buffer status table and enhanced configured grant.Finally,the simulation results and performance analysis show that the proposed enhancement mechanisms can better support the extended reality services.
