Problems solved by technology

However, in point-to-point communication, in order to save power consumption, some subframes may not need to send data, so the automatic gain control (AGC) setting of the receiving end can only use the historical value when receiving, and the channel estimation can only use the reference symbol in the data ( RS) to carry out
When the communication environment is relatively harsh (such as many obstacles, complex geographical environment and high-speed movement), there are certain deficiencies in performance

Abstract

The invention provides a point-to-point communication method and a point-to-point communication system. According to the method of the invention, a physical layer frame is used between a first end and a second end for communication, the physical layer frame comprises a preamble sequence and a physical data channel, the preamble sequence is used for real-time tracking on automatic gain control and channel estimation, and the physical data channel is used for bearing data transmission of the physical layer.

Description

technical field [0001] The present invention mainly relates to the field of mobile communication, in particular to a point-to-point communication method and system. Background technique [0002] In some new application scenarios, such as Internet of Vehicles and drones, point-to-point communication that does not depend on the network is used. The scenarios used in point-to-point communication can be static communication or mobile communication. As typical applications, the Internet of Vehicles and drones are high-speed mobile communications. Taking drones as an example, when drones take real-time aerial photography, wireless transmission of large amounts of data is required. High-speed movement and real-time transmission of large amounts of data are new problems in point-to-point communication. [0003] There is no unified frame structure in the existing point-to-point communication methods. Taking unmanned aerial vehicles as an example, the most commonly used communicat...
