“…We briefly introduce the previous works and discuss their differences from these existing works. Note that the measurement campaigns in other scenarios (e.g., outdoor [15] or indoor scenarios with longer receiver (RX)-transmitter (TX) distances [16,17]) are excluded from the following discussion. Moreover, our focus is on generating CIRs in a static environment because the user equipment is likely to be static in the FR2-2 use case, similar to the devices in IEEE 802.15.3c WPANs.…”

IEEE OJAP encourages responsible authorship practices and the provision of information about the specific contribution of each author. the assumed ICD lies in the aforementioned range [8].Meanwhile, revisiting the standardization history of the communication systems exploiting this FR2-2 band, the 5G NR operated in this band is also likely to support shorterrange communications, that is, wireless personal area network (WPAN)-like or wireless local area network (WLAN)-like scenarios. In more detail, the first standardization activity for the communication system operating at 60 GHz was devoted to realizing mmWave WPAN systems by the IEEE 802.15.3c task group [9]. Therein, indoor scenarios with a communication distance of

“…The segregation comes at the expense of additional equipment and costs to replace all cable-based synchronization either between the LOs or between the signal generator and spectrum analyzer. Global positioning system (GPS)-assisted synchronized Rb clock [57] or high precision Synchronomat based on Rb clocks [58] is used for synchronizing the LOs at the two ends. In addition, high-precision LO consisting of phase-locked dielectric resonator oscillators can be used in place of the internal clocks of the standard LOs [11].…”

“…In addition, high-precision LO consisting of phase-locked dielectric resonator oscillators can be used in place of the internal clocks of the standard LOs [11]. The internal trigger pulses of the signal generator (SG) and the spectrum analyzer (SA) are synchronized using a direct cable connection during calibration but separated during actual measurement [57]. However, during long measurements, the Rb clocks or the trigger pulses of the SG and SA might fall out of sync and hence the synchronization procedures have to be repeated.…”

As the world warms up to the idea of millimeter wave (mmWave) communication and fifth generation (5G) mobile networks, realization slowly dawns that the data rate, latency, throughput, and other performance metrics that are used to assess a new wireless communication technology will not be enough to support the demands of envisioned futuristic applications. Thus there is an eagerness to further climb up the frequency ladder to use the large swathes of available spectrum in the 0.1 − 10 THz band which is expected to act as the key technology enabler to fulfill the requirements of the sixth generation (6G) wireless communication and possibly even beyond. Channel measurement and modeling are crucial to the design and deployment of future wireless communication systems and researchers across the world are putting their best foot forward to accelerate the process. The present article presents comprehensive assimilation of research efforts in the context of THz channel sounding. A detailed overview of the current channel sounding techniques is first introduced followed by their relevance to THz band channel measurement. An in-house novel channel sounder developed for THz band measurement is also briefly introduced in this context. The paper next provides elaborate dissemination of various measurement campaigns in the band of interest followed by the modeling techniques that are available in the literature and are being adopted for the THz band. Post the description of different challenges and future research directions in the context of sounding, measurement, and modeling the article is concluded.
