6G universal channel modeling method suitable for full-band and full-scene

Abstract

The invention discloses a 6G universal channel modeling method suitable for a full frequency band and a full scene. The method specifically comprises the following steps: S1, setting a propagation scene and a propagation condition, and determining a carrier frequency, an antenna type, a receiving and transmitting end layout and the like; s2, generating large-scale fading such as path loss, shadow fading and blocking effect; s3, generating large-scale parameters with spatial consistency; s4, a scatterer position obeying ellipsoid Gaussian scattering distribution is generated, the time delay, angle and power of the cluster are calculated according to the positions of the receiving and transmitting end and the scatterer, and a channel coefficient is generated; and S5, updating large and small scale parameters according to the motion of the transmitting and receiving end and the birth and extinguishment process of the cluster, and generating a new channel coefficient. The 6G pervasive geometric random channel model disclosed by the invention is the only one channel model which can be universally suitable for full-band, full-coverage scenes and full-application scenes in the industry at present, and is crucial for 6G channel model standardization, 6G generality theory technology research and system fusion construction.

Description

technical field [0001] The invention relates to a 6G pervasive channel modeling method suitable for all frequency bands and all scenarios, and belongs to the technical field of wireless communication. Background technique [0002] 6G wireless channels can be summarized into full frequency bands (sub-6GHz / millimeter wave / terahertz / optical wireless frequency bands), full coverage scenarios (air-space-earth-sea integration, including satellite, UAV, land and marine communication channels) and full applications Scenario (Internet of Vehicles, high-speed rail channels, large-scale antenna arrays, reconfigurable smart surfaces, industrial IoT, etc.) channels, as follows figure 2 shown. At the same time, the 6G full-band full-scenario channel also exhibits many new channel characteristics, which brings new challenges to the 6G channel modeling work. [0003] In the whole frequency band, due to the application of high frequency bands such as millimeter wave and terahertz, the wire...

Problems solved by technology

5G standardized channel models such as B5GCM, 3GPPTR38.901, IMT-2020 and QuaDRiGa have made attempts on this issue, but none of them can accurately and comprehensively describe all the aforementioned characteristics

In terms of the full spectrum, these models are not suitable for the visible light band, and more or less ignore some characteristics of the millimeter wave / terahertz band, such as QuaDRiGa ignores the modeling of atmospheric absorption and blocking effects, 3GPP TR 38.901 and IMT -2020 ignores the frequency non-stationary characteristics of the high frequency band; in terms of full coverage, these channel models are all for land mobile communication channels, and cannot be applied to satellite, UAV and ocean communication scenarios; in terms of full application, they are not Supports modeling of hyper-high-speed rail channels, reconfigurable smart surfaces, and industrial IoT channels, and, 3GPP TR 38.901 and IMT-2020 do not consider spherical waves and spatial non-stationary properties of (ultra) large-scale antenna arrays

In summary, these models still lack universality and do not consider all the channel characteristics mentioned earlier
