Abstract

The invention discloses an intelligent metasurface control method, device and system based on time division multiplexing, belonging to the technical field of wireless communication, including: determining the reflection coefficient of each reflection unit of the intelligent metasurface; converting the reflection coefficient into a corresponding control signal; by means of time division multiplexing, the control signal is output to the smart metasurface in parallel to control the reflection units. In this way, on the one hand, the present invention implements time-division multiplexing of the controller pins to realize the purpose of using a small number of controller pins to control large-scale reflection units, thereby saving the cost of the intelligent metasurface system and improving the utilization efficiency of the controller; On the one hand, a layer of buffer is added between the controller and the smart metasurface, which is conducive to the proper isolation of the controller and the smart metasurface, and avoids all damage after failure.

Description

Technical field [0001] The present invention belongs to the field of wireless communication technology, more particularly, relates to an intelligent hypersurface control method based on time division multiplexing, apparatus and system. Background [0002] In the field of 5G wireless communication and even the future of 6G wireless communication, millimeter wave technology has an extremely important role as a key technology, but millimeter wave has a very fatal defect, and the loss when encountering obstacles is serious, resulting in unsatisfactory communication effects. [0003] To solve this problem, the prior art is to add a specially manufactured, low-cost, programmable smart hypersurface (RIS / Large Intelligent Surface / Reconfigurable IntelligentSurface / Software Defined Surface / Metasurface / IRS / Intelligent) to the wireless communication environment ReflectingSurface / Reconfigurable Meta-Surfaces / Holographic MIMO, etc., hereinafter expressed in RIS) to assist communication. The ma...
