3GPP TR 38.901 Channel Model

Abstract: The 3rd Generation Partnership Project (3GPP) recommends an accurate and compatible stochastic channel model for 0–100 GHz frequency band, which is useful to design, optimize, and evaluate the fifth‐generation (5G) systems. This standardized model can be acquired by generating the large‐ and small‐scale fading models. This article firstly reviews the main existing channel models suitable for millimeter‐wave (mmWave) frequency band as well as the typical channel modeling methods, i.e. the deterministic and stoc… Show more

“…To highlight the impact of posture instead of the multipath propagation, the birth-death process of clusters in NLoS paths and the delay variations caused by moving of clusters are omitted. The simulated U2V communication system operates at 2.4 GHz and the path and sub-path angles are assumed to follow the 3GPP 38.901 standard definition [39,35]. The mean value of the Ricean K-factor is set as 7 and the variation is set as 4, which means the LoS component is also timevariant.…”

“…Even amongst different deterministic or stochastic approaches, there are variations in their benefits and limitations. To address such challenges and provide an optimum solution different hybrid approaches combining different deterministic approaches [166], [240], [241] or deterministic and stochastic approaches [96], [242]- [247] are proposed. The details of such trade-offs are further elaborated in subsubsections IV-C1 and IV-C2.…”

“…The size of the cells and channel model change according to different scenarios [ 39 ], which are referenced from the test scenior in the 3GPP protocol, such as UMa, RMa, RMi. By default, the outsider scenario of the non-line-of-sight of the RMa was selected to evaluate the proposed method.…”

“…In the traditional MADRL, since the complex communication environments usually contain a large amount of information, uniform experience replay leads to poor stability and the slow convergence of neural networks; (2) It weakens the interconnectivity between agents, especially in the system where the agent plays a direct role with the other agents (for example, an agent promotes individually and hinders others). Therefore, the traditional MADRL, which uses a distributed training process to explore solutions, is unsuitable for finding the action characteristics of each agent; and (3) It is not realistic to simplify the channel with a free-space propagation model, since some test scenarios are neglected in different channel models [39], including the urban macro-cell (UMa), rural macro0cell (RMa), and rural micro-cell (RMi) in IMT-2020.…”
