Channel prediction method and device for pre-deployment of mobile air base station

Abstract

The embodiment of the invention provides a channel prediction method and device for pre-deployment of a mobile air base station. The method comprises the following steps: constructing a three-dimensional environment model at a to-be-predicted moment according to environment data at the to-be-predicted moment and behavior data at the to-be-predicted moment; and configuring communication parametersin the three-dimensional environment model at the to-be-predicted moment, and obtaining channel parameters at the to-be-predicted moment through a ray tracing method. The space-time correlation of marine environment information and ship route information are utilized to predict marine environment changes, so that a predicted three-dimensional environment model is constructed, and channel parameterinformation is estimated in the predicted three-dimensional environment model. The channel prediction method effectively adapts to the change of a marine environment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel prediction method and device for pre-deployment of mobile base stations in the air. Background technique [0002] The industry and academia at home and abroad use mobile air platforms to build air communication systems, and cooperate with ground mobile communication systems, satellite communication systems and ship networking to realize broadband Internet access in sea areas and improve the broadband experience of sea users. For example, the use of airships, which work in the stratosphere and can cover large areas, are called high-altitude pseudo-satellites. [0003] In addition, drones have attracted much attention. Utilizing the characteristics of flexible movement of UAVs, UAVs are used as a pre-deployment platform for mobile air base stations. In the vast sea, mobile air base stations are pre-deployed according to communication needs to achieve on-de...
