Method, device and system for adjusting sending rate in near field communication scene

Abstract

The invention provides a method, device and system for adjusting a sending rate in a near field communication scene, relates to the technical field of communication, and can improve the performance of a rate adjustment scheme in the near field communication scene. The method is applied to data sending equipment, and comprises the following steps: acquiring connected transmission layer information, physical layer channel information of a sending link where the sending equipment is located, and physical layer channel information of a receiving link where data receiving equipment is located; and according to the transmission layer information, the physical layer channel information of the sending link and the physical layer channel information of the receiving link, adjusting the sending rate of the transmission layer of the sending equipment, wherein the connection is the connection between the sending equipment and the receiving equipment. The method is applied to a flow of adjusting the sending rate in a near field communication scene.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office on June 30, 2020, with the application number 202010624214.1, and the title of the invention is "Method, device and system for adjusting transmission rate in near-field communication scenarios", all of which The contents are incorporated by reference in this application. technical field [0002] The present application relates to the field of communication technologies, and in particular to a method, device and system for adjusting a sending rate in a near field communication scenario. Background technique [0003] At present, the data of electronic products held by users has surged, and the communication requirements for electronic products have also increased.

Problems solved by technology

The above congestion control technologies can adjust the sending rate of the transmission layer of the sending end to a certain extent. However, in the near-field wireless communication scenario, the time-varying wireless channel is obvious, and it is difficult for the sending end to accurately increase the sending window to adjust to a suitable transmission layer. Sending rate, specifically, if the sending rate of the transport layer is slow, the throughput will be affected and the link bandwidth cannot be fully utilized; if the sending rate of the transport layer is fast, it will cause a large queuing delay or even packet loss

[0005] It can be seen that in the near-field wireless communication scenario, the current transmission layer transmission rate adjustment scheme has poor performance in transmission layer transmission rate adjustment
