Problems solved by technology

[0003] However, on the one hand, since the smart surface does not have complex digital baseband processing capabilities, it is difficult to estimate the channel from the smart surface to the user, that is, it is difficult to adaptively adjust the parameters of the electromagnetic unit to achieve the purpose of user tracking
On the other hand, the user may be transparent to the smart surface, that is, the user may not know the existence of the smart surface

Abstract

The invention provides an intelligent surface control method and related equipment thereof, and relates to the technical field of communication. The control method comprises the following steps: monitoring first control information, wherein the first control information is used for opening or closing an intelligent surface; when the intelligent surface is in the on state, second control information and / or third control information are / is monitored, the second control information is used for adjusting the electromagnetic unit period of the intelligent surface, and the third control information is used for adjusting the electromagnetic unit regulation and control parameter set of the intelligent surface. Through reasonable distribution and utilization of the intelligent surface switch control information, the electromagnetic unit period adjustment information and the electromagnetic unit regulation and control parameter group setting information, effective control of the intelligent surface is realized.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a smart surface control method and related equipment. Background technique [0002] Intelligent Reflecting Surface (IRS, Intelligent Reflecting Surface), also known as Reconfigurable Intelligent Surface (RIS, Reconfigurable Intelligent Surface) (for the convenience of description, the subsequent collectively referred to as intelligent surface) is composed of a large number of low-cost electromagnetic units, which can be The parameters of the unit (such as phase) are adjusted to control the reflection direction of the signal incident on the smart surface, so that the signal is reflected in the desired direction. Due to the characteristics of low cost, low power consumption, and easy deployment, smart surfaces are expected to become candidate technologies for 6G wireless communications. [0003] However, on the one hand, since the smart surface does not have ...
