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...
