Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0048] The present invention relates to a multi-beam distributed power MAC protocol communication method, which relies on the multi-beam antenna structure MAC protocol communication method, and makes full use of the limited transmission power of the transceiver through a distance-aware distribution method, thereby achieving an increase in the multi-input multi-output too Hertz for communication network throughput purposes.

[0049] In the present invention, the process of a node transmitting a data packet to another node is divided into two stages, which are the control information transmission stage using 2.4GHz and the terahertz data transmission stage. Due to the serious path loss in the terahertz channel and the limited transmission power of the nodes, there is an upper limit to the number of te...

Abstract

The invention relates to a multi-beam distribution power MAC protocol communication method, which combines 2.4 GHz and terahertz frequency band communication, controls information to be transmitted ina 2.4 GHz frequency band, and does not influence the stability of terahertz frequency band data transmission. By combining a distance-aware power distribution method with a multi-beam terahertz antenna design, the limited transmission power of a transceiver is fully utilized, and multiple-input-multiple-output terahertz communication is realized in a distributed network, and the power utilizationrate and the network throughput are maximized. Compared with a method for distributing transmission power according to needs, the multi-beam distribution power MAC protocol communication method solves the problem of excessive saving, and prevents idle power from being generated; and the throughput of the network is maximized while the limited transmission power of a single node is fully utilized.

Description

technical field [0001] The present invention relates to a radio transmission system, that is, the technical field using a radiation field, and in particular to a multi-beam distributed power MAC protocol communication method for a multi-input multi-output terahertz communication network. Background technique [0002] With the explosive growth of wireless data traffic in recent years, data transmission rates are expected to soon need to reach terabits per second (Tbps), however, the upcoming 5G network can only provide transmission speeds of gigabits per second (Gbps); In the face of people's ever-increasing demand for higher data transmission rates and limited electromagnetic spectrum resources, Terahertz (Terahertz, THz, 0.1-10THz) communication is considered to be one of the key technologies to realize the next generation of ultra-high-speed wireless communication systems . [0003] However, there is a serious path loss in the terahertz frequency band. If you want to achi...
