Priority-Based Intelligent Reflecting Surface for Uplink 6G Communication

Abstract

The sixth-generation (6G) wireless communication network will be implemented to launch the intelligent information system, which is extensively digitized, fascinated by intelligence, and guided by global data. The 6G network can serve a large number of devices with extremely low network latency while also being more reliable and convenient, but the Line-of-Sight (LOS) cut constraint is a major challenge for expanding coverage. The concept of Intelligent reflecting surface (IRS) has recently drawn a great deal of interest as a promising approach for increasing wireless coverage, cost-effectiveness, and power efficiency for 6G wireless communication. To improve communication performance, IRS is able to dynamically switch wireless channels. The majority of recent publications on IRS take into account frequency-flat channels and presuppose that the broadcaster has perfect knowledge of channel state information (CSI). A Priority-based Intelligent Reflecting Surface for uplink 6G Communication is proposed in this paper for frequency-selective channels and a practical uplink subcarrier channel estimation. While determining minimum subcarrier bandwidth, a stringent end-to-end latency requirement of 0.1 ms is maintained for different 6G network services ensuring faster and more effective data transmission reliability of 99.9999%.
