Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a millimeter wave communication system. Background technique [0002] With the development of services such as smart 8K video, VR, online games, and smart home interconnection, the demand for wireless data transmission rates is increasing, and is developing from hundreds of Mbps to thousands of Mbps. In 2020, IEEE released the 802.11ax standard, which operates in the 2.4GHz and 5GHz license-free frequency bands. At the same time, technologies such as MU-MIMO, 160MHz bandwidth, and 1024QAM high-order coding were introduced to achieve a maximum transmission rate of 9.6Gbps. In 2019, IEEE established the 802.11be standard working group to increase the theoretical maximum rate from 9.6Gbps of 802.11ax to 30Gbps of 802.11be. However, the interference in license-free frequency bands such as 2.4GHz and 5GHz is quite serious, and its application in the real environment is ...

AI Technical Summary

Problems solved by technology

However, the interference in license-free frequency bands such as 2.4GHz and 5GHz is quite serious, and its application in the real environment is limited, especially for 160MHz bandwidth technology. Due to the existence of interference, the working bandwidth will degenerate to 80MHz, 40MHz or even 20MHz, and the data transmission rate is rapid decline, increased latency, and extremely unstable performance

In the licensed frequency band below 6GHz, available bandwidth resources are also very scarce, especially it is difficult to obtain large continuous bandwidth, which brings a bottleneck to the development of mobile communication
