“…In [14], [15], a RoF-enabled channel sounder at 28 GHz with a measurement range of up to 300 m and at 300 GHz with a measurement range of up to 600 m were reported, with a focus on system design, link budget, and back-to-back and field measurements. Such schemes are also extensively employed in [16] to support the D-band channel measurements.…”

To support research and development for sixthgeneration (6G) communication, it is imperative to understand the application needs and develop accurate and realistic channel models to meet the application needs. Several key radio technologies are identified for 6G research, including utilization of frequency bands ranging from sub-6 GHz to THz, antenna configuration covering simple single antenna to complicated gigantic multiple-input and multiple-output (MIMO) systems, and diverse deployment scenarios requiring various measurement ranges. This paper summarizes latest strategies to significantly extend the capabilities of current vector network analyzer (VNA)-based channel sounder, mainly radio-over-fiber (RoF) to enable longrange channel measurements, phase compensation to achieve accurate and coherent phase measurement, frequency extension to extend the carrier frequency and frequency bandwidth, and virtual antenna array (VAA) schemes to enable multiantenna/link channel measurements.

For 5G beyond and/or 6G mobile services, a new spectrum at frequencies above 100 GHz has received great attention lately. To characterise the similarities and the differences between frequencies below 100 GHz and above 100 GHz, this paper provides analyses of multi‐frequency propagation characteristics based on wideband measurements at 28, 38, 71, 82, and 159 GHz, with an emphasis on the sub‐THz (i.e. the 159 GHz) propagation characteristics. All the frequency measurements were conducted in the same cubicle office room environment by locating the transmitter and the receiver at the same positions. The measurement results show that the path loss and the shadow fading characteristics do not exhibit significant differences depending on the frequency range from 28 to 159 GHz. However, the delay spread shows a generally decreasing trend as the frequency increases. Additionally, angular domain analyses were conducted with the 159 GHz measurements.

Sub-terahertz (THz) communication is envisioned as one of the key components for 6G because of the abundantly available spectrum resource. Accurate and efficient channel models are prerequisites for developing sub-THz communication systems. Due to the sparsity and more ray optics propagation characteristics of the sub-THz channel, deterministic Ray-Tracing (RT) has attracted much attention for sub-THz channel modeling, which shows the potential of reducing the simulation complexity yet maintaining the accuracy. This paper presents an implementation of RT for sub-THz channel modeling and demonstrates its performance based on sub-THz channel measurements. A virtual massive multiple-inputmultiple-output (MIMO) channel operating at 100 GHz and a double-directional 300 GHz channel are considered in the RT implementation, where the RT achieves a high similarity compared to the channel measurements in terms of channel impulse response and power angular spectrum. Besides, the near-field and spatial non-stationary properties of the sub-THz massive MIMO channel and the dominant multipaths of the 300 GHz channel are accurately reconstructed in the RT simulation. This work can provide insights into deterministic sub-THz channel modeling research from the implementation, evaluation, and challenges perspectives.
