Therefore, when the link quality is poor, it will lead to a large number of "waiting" and "retransmission" processes. These retransmissions occupy valuable network resources and cause huge transmission delays. For portable devices, this also means waste of battery power

Embodiment Construction
[0015] A physical layer adaptive processing method for improving network transmission reliability. When the communication quality indicator signal drops below a certain threshold, the MAC at the sending end of the network communication protocol stack increases the load of user data in a physical frame layer. Regularly repeat, interleave, and evenly insert more cyclic redundancy check CRC bytes; at the same time, add corresponding de-interleaving, de-duplication, and segmental judgment cyclic redundancy check to the media access layer MAC at the receiving end of the network communication protocol stack. Check the CRC.

The invention relates to a physical layer self-adaption processing method for improving network transmission reliability. In network communication, when a communication quality indicating signal is decreased below a certain threshold, CRC bytes which are regularly repeated, interwoven and densely and evenly inserted and belong to user data loads in a physical frame layer are added to the sending end media access layer MAC of a network communication protocol stack; meanwhile, the method of adding corresponding CRCs which are de-interwoven, remove duplicates and are judged in a subsection mode to the receiving end media access layer MAC of the network communication protocol stack guarantees error-free transmission of information. Communication reliability is effectively improved when network communication quality is poor, the probability of successfully transmitting the user data loads is improved, and network resource waste and energy consumption of terminal equipment caused by retransmission by requested repeatedly are avoided.
Description
technical field [0001] The invention relates to a physical layer adaptive processing method for improving network transmission reliability, and belongs to the technical field of wireless local area network transmission. Background technique [0002] The current network communication covers a large aspect of communication technology. Usually network communication follows the layered model of OSI. The bottom layer of the layered model is MAC layer (media access control layer, media access layer) and PHY Layer (physical layer, physical layer). In the current relatively common wireless network transmission technology field, Bluetooth and ZigBee are more and more widely used. In these transmission protocols, PHY does not have special FEC (forward error correction, former Error correction) for error correction protection, only rely on the "error detection - retransmission" mechanism for data transmission. Therefore, when the link quality is poor, it will lead to a large number o...
