Bidirectional intelligent reflection unit selection method

Abstract

The invention provides a bidirectional intelligent reflection unit selection method, which comprises the following steps that: a user I and a user II work in the same frequency band, the user I and the user II carry out receiving and transmitting at the same time, and the user I completes communication with the user II through cooperation of an intelligent reflection unit selected from a plurality of intelligent reflection units, the intelligent reflection unit with the minimum two-way transmission outage probability is taken as a selected intelligent reflection unit; the user I and the user II serve as sending ends to send information and serve as information sinks to receive information sent by the opposite side through the selected intelligent reflection unit. According to the method, the intelligent reflection unit with the minimum two-way transmission outage probability is selected for auxiliary communication, so that the wireless communication performance of the Internet of Things is remarkably improved, and the wireless communication quality is also enhanced.

Description

technical field [0001] The invention relates to a method for selecting a bidirectional intelligent reflection unit, which belongs to the technical field of wireless communication. Background technique [0002] The Internet of Things technology deploys a large number of nodes, which often need to communicate with each other. Due to the large deployment area of ​​the nodes, sometimes two nodes cannot communicate directly, and an auxiliary communication module is required to participate in this case. The intelligent reflection unit is a new auxiliary communication module, which has low power and easy deployment compared with traditional relays. The intelligent reflection unit can effectively improve the network transmission performance by reflecting the data signal, and spread the radio wave to a farther position better, providing an effective technical means. [0003] For example, Chinese patent application CN202011490400.7 discloses a communication method, system and device...

Problems solved by technology

[0006] In view of the above problems, the object of the present invention is to provide a method for selecting a two-way intelligent reflection unit. During two-way communication, an appropriate intelligent reflection unit is selected according to the probability of bidirectional transmission interruption, so as to ensure the efficient operation of the Internet of Things system and solve the problems existing in the prior art. The wireless communication performance and communication quality need to be improved when the two-way wireless information transmission is carried out
