Wireless digital communication method

Abstract

The invention discloses a wireless digital communication method, which relates to the technical field of wireless communication. By the method, the communication flexibility of a wireless audio transmission system can be improved, the resource utilization rate of the system can be increased and the power consumption of the system can be effectively reduced. The wireless digital communication method provided by the embodiment of the invention comprises the following steps of: receiving frame structure regulation information from a transmitter, wherein the frame structure regulation information comprises radio frequency packet regulation information and is generated according to communication state indication information when the transmitter learns that a communication state is changed, and the communication state indication information indicates a receiver state and / or a channel state; and regulating a used frame structure by utilizing the frame structure regulation information, and performing data communication with the transmitter according to the regulated frame structure. The scheme is applied to a plurality of wireless communication systems with relatively higher requirements on transmission quality.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless digital communication method. Background technique [0002] With the advancement of wireless digital transmission technology, especially based on the 2.4GHz frequency band, the appearance of a system-on-chip with low power consumption, low radiation, and low cost has made wireless digital transmission technology widely used in wireless digital audio products. possible. [0003] At present, wireless digital audio transmission technology mainly includes three types of wireless transmission technologies based on Wireless Fidelity (WiFi), Bluetooth and 2.4G. Among them, the wireless audio transmission technology based on WiFi has the advantages of high bandwidth, but due to the large transmission power of WiFi, it causes problems such as high energy consumption and high radiation; There is a high delay on the Internet; the wireless transmission tec...

Problems solved by technology

[0006] This existing processing method causes a waste of system bandwidth resources and increases system power consumption. For example, the existing wireless audio communication method is only for communication systems in fixed scenarios, and the pre-set frame structure is only applicable to this fixed scene. The communication method of the sending end and the earphone end in the scene is not flexible enough, and when the communication scene changes, the pre-set frame structure may no longer be applicable to the new scene, resulting in the inability to transmit audio data; and the existing frame In the structure, multiple retransmission packets are set for the data packet, and when the data packet is transmitted normally, there is no need to retransmit the data. In this existing processing method, in any case, each frame transmitted includes multiple A retransmission packet not only wastes the bandwidth of the system, but also increases the power consumption of the sending end and the earphone end
