“…Firstly, the low sub-THz band may alleviate the challenges for the hardware cost. Secondly, this band retains similar propagation characteristics to the mmWave band [9,10], and we can hypothesize that the short-range communication can be designed with the analogy from the already established mmWave short-range communication systems, that is, 60 GHz WPAN systems such as IEEE 802.15.3c [5] and IEEE 802.11ad [11].…”

“…Recently, a channel model applicable to the low sub-THz band has been developed for indoor short-range communication systems [6]. This channel model is designed based on a propagation measurement at 93-97 GHz in a compatible manner with the well-known 3GPP stochastic channel model (SCM).…”

“…Second, 3GPP SCM assumes the same intra-cluster characteristics for all clusters, such as intracluster delay spread, intra-cluster azimuth AoA spread, and the number of intra-cluster rays, but there is variation from cluster to cluster in reality. Hence, the model proposed in [6] redesigned a distribution model of cluster azimuth AoA, intracluster delay spread, intra-cluster azimuth AoA spread, and the number of intra-cluster rays as uniform distribution, I. Moreover, to reflect this channel characteristic on the subsequent transmission performance evaluation, we generate ten samples of channel responses based on the aforementioned model.…”

“…6. For conversion from the SNR to communication distance, the path loss model for the low sub-THz band proposed in [9] and the parameters shown in Table IV were used. From this figure, it is found that PSCCH and PSSCH of the 2nd-stage SCI carrying the control information can be received with BLER below 0.1 within 2.5 m; hence, a meter-level communication is feasible.…”

The simulation leverages a recently developed channel model improved for indoor short-range communication in a low sub-THz band of 93-97 GHz [6].

To meet increasing demands for higher-rate communication, exploring the sub-terahertz (THz) band is attracting huge attention. The first standardization of a sub-THz communication was performed at the IEEE 802.15.3d task group, which designed an ultra-wideband short-range communication operating in a 300 GHz band. However, to alleviate hardware challenges, the usage of a much lower-sub-THz band, that is around 100 GHz, should also be considered. Moreover, in terms of the advantage of using signal processing circuits common to 5G new radio (NR), the frame format should be designed in a compatible manner with the commercially pervasive 5G NR, which cannot be reached by IEEE 802.15.3d. Motivated by these backgrounds, this paper proposes a 5G NR-based ultra-wideband short-range communication operating in a low sub-THz band that lies in 90-110 GHz. This can be achieved by using 5G NR sidelink communication with the bandwidth expansion to several GHz, and no changes are made for the frame format to retain compatibility. This study conducts a performance evaluation of such a 5G NR sidelink system with a 4 GHz bandwidth by using a recently developed channel model at the 93-97 GHz band. The evaluation reveals that the proposed communication system using the 5G NR sidelink can achieve a block error rate (BLER) equal to 0.1 for both control and user-data transmissions even when a 4 GHz bandwidth is utilized. Moreover, it is shown that transmission at a meter-level distance is feasible even when an omnidirectional antenna in an azimuth plane is used.

This paper proposes a comprehensive 3GPPcnaompatible channel model with statistical enhancement tailored for indoor short-range device-to-device (D2D) communications operating in the frequency range (FR) of 52.6-71.0 GHz termed FR2-2. Regardless of the existence of various channel models at this band for indoor communications, there will be a need for developing a channel model compatible with and understandable from the current 3GPP stochastic channel model (SCM) to facilitate the discussion in the 3GPP for developing such FR2-2 short-range D2D communication framework based on the fifthgeneration (5G) new radio (NR). Indeed, such a futuristic vision can be foreseen from the fact that the 3GPP is discussing the evolution of sidelink, referred to as a D2D communication framework; however, there are no 3GPP SCM-compatible channel models applicable to FR2-2 short-range D2D communications. To fill this void, we propose the channel model coined 3GPPCompFR2-InS that allows us to generate channel impulse responses (CIR) for computer simulations, which is suitable for various indoor short-range D2D communication scenarios while retailing the similarity in terms of the implementation policy of the 3GPP SCM. 3GPPCompFR2-InS is verified based on the real-world measurements at the 60 GHz band from the viewpoint of both the validity of the channel model parameters and that of the statistical behavior of the generated CIRs.
