Communication system, method, device and storage medium

Abstract

Provided in an embodiment of the present invention are a communication system, method, device and storage medium, the system comprising: a base station, a reflecting surface and a plurality of user terminals, each user terminal broadcasting a pilot signal; the base station receiving the first receiving signal, analyzing the first receiving signal, calculating to obtain corresponding channel state information, and further determining a target configuration parameter of the reflecting surface; the reflection surface adjusting self configuration according to the target configuration parameters to obtain an adjusted reflection surface; the base station encoding a plurality of pieces of data information to be sent into a data packet, and broadcasting a base station signal carrying the data packet; the adjusted reflecting surface receiving a second receiving signal, and reflection phase shift and reflection amplitude being applied to the second receiving signal to obtain a reflection signal; and each user terminal receiving the third receiving signal and decoding the third receiving signal to obtain the to-be-sent data information corresponding to the user terminal. Therefore, the transmission delay of the communication system is reduced under the condition that the bit error rate is controlled as much as possible.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication system, method, device and storage medium. Background technique [0002] A communication system generally includes a source (sending device), a sink (receiving device) and a channel (transmission medium), etc. When the source sends data information (such as sound, image, text, etc.) to the sink, it first encodes the data information, It is transmitted to the sink in the form of a signal through the channel, and the sink decodes the signal to obtain the data information sent by the source. [0003] With the development of communication technology, the requirements for the transmission delay (the time it takes for data information to be sent from the source to the destination) and bit error rate (the index to measure the accuracy of the data information transmitted within a specified time) of the communication system are increasing. For example, the p...

[0005] However, the above scheme ignores that the transmission delay in the communication system is proportional to the code length. The longer the code length, the longer the transmission delay. Moreover, if the user terminal is in a relatively complex environment, such as a city, factory, etc. In the environment, when the signal broadcast by the base station encounters an obstacle, path loss will occur, and the signal power received by the user terminal will be correspondingly weakened, resulting in a decrease in the achievable rate of transmitting data information to be sent in the communication system and an increase in transmission delay
