“…It should be noted that sensing should be codesigned with communication in 6G wireless systems. The Joint Communication and Sensing (JCAS) is an integral part of the 6G networks [59]. The massive MIMO systems, RIS, mmWave signals, Terahertz signals, and many other wireless technologies provide high resolution of sensing.…”

Extended Reality (XR) is an umbrella term that includes Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). XR has a tremendous market size and will profoundly transform our lives by changing the way we interact with the physical world. However, existing XR devices are mainly tethered by cables which limit users' mobility and Quality-of-Experience (QoE). Wireless XR leverages existing and future wireless technologies, such as 5G, 6G, and Wi-Fi, to remove cables that are tethered to the head-mounted devices. Such changes can free users and enable a plethora of applications. High-quality ultimate XR requires an uncompressed data rate up to 2.3 Tbps with an end-to-end latency lower than 10 ms. Although 5G has significantly improved data rates and reduced latency, it still cannot meet such high requirements. This paper provides a roadmap towards wireless ultimate XR. The basics, existing products, and use cases of AR, MR, and VR are reviewed, upon which technical requirements and bottlenecks of realizing ultimate XR using wireless technologies are identified. Challenges of utilizing 6G wireless systems and the next generation Wi-Fi systems and future research directions are provided.

The sixth-generation (6G) network is expected to provide both communication and sensing (C&S) services. However, spectrum scarcity poses a major challenge to the harmonious coexistence of C&S systems. Without effective cooperation, the interference resulting from spectrum sharing impairs the performance of both systems. This paper addresses C&S interference within a distributed network. Different from traditional schemes that require pilot-based high-frequency interactions between C&S systems, we introduce a third party named the radio map to provide the large-scale channel state information (CSI). With large-scale CSI, we optimize the transmit power of C&S systems to maximize the signal-to-interference-plus-noise ratio (SINR) for the radar detection, while meeting the ergodic rate requirement of the interfered user. Given the non-convexity of both the objective and constraint, we employ the techniques of auxiliary-function-based scaling and fraction programming for simplification. Subsequently, we propose an iterative algorithm to solve this problem. Simulation results collaborate our idea that the extrinsic information, i.e., positions and surroundings, is effective to decouple C&S interference.

To accommodate the ever-growing data requirements in densely populated areas and address the need for high-resolution sensing in diverse next-generation applications, there is a noticeable trend towards utilizing large unallocated frequency bands above 100 GHz. To overcome the harsh propagation conditions, large-scale antenna arrays are crucial and urge the need for cost-effective, mass-manufacturable technologies. A dedicated Any-Layer High Density Interconnect PCB technology for highly efficient wireless D-band (110–170 GHz) systems is proposed. Specifically, the adapted stack accommodates broadband air-filled substrate-integrated-waveguide components for efficient long-range signal distribution and low-loss passives. The viability of the suggested technology platform is demonstrated by designing, fabricating and measuring several essential low-loss air-filled substrate-integrated-waveguide components, such as a dual rectangular filter, with a minimal insertion loss of 0.87 dB and 10 dB-matching within the (132.8–139.2 GHz) frequency band, and an air-filled waveguide with a routing loss of only 0.08 dB/mm and a flat amplitude variation within 0.01 dB/mm over the (115–155 GHz) frequency range. A broadband transition towards stripline, with a limited loss of 1.1 dB, is described to interface these waveguides with compactly integrated chips. A tolerance analysis is included as well as a comparison to the state of the art.
