The explosive growth of immersive and metaverse services has driven the demand for extended reality(XR)transmissions across wireless networks.XR 360° video,captured by omnidirectional cameras and supported by interactive sensors,often provides users with unique immersive experiences and real-time interactions.However,the ultra-high data rate and ultra-low latency requirements for XR 360° video transmissions present new signal processing challenges for XR communication systems.This paper pro-vides a comprehensive survey of promising physical layer signal processing technologies for XR communica-tions and systems.These include multiple antenna technologies for XR,mmWave/terahertz waves for XR communication,machine-learning-based XR transmission,and resource allocations for XR communications.Additionally,we propose a novel signal processing and transmission framework that fully exploits the space-time-frequency dimensions of virtual reality communications.Finally,we summarize the current technical challenges in signal processing for XR communications and related systems and discuss future trends in XR communications.
