MPDU Header-Body Separation for Reliable High-Efficiency Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of transmitting medium access control protocol data units (MPDUs) with separate reliable coding for headers and bodies on the same resource results in low transmission efficiency, particularly in scenarios with high reliability requirements.
Innovation Solution
Implementing the transmission of frame header and frame body information in a separation manner, where the frame body information is transmitted in a manner to a receive end and the transmission of the frame header and the frame body are carried separately in a PPDU and a PPDU and a PPDU and a PPDU and a PPDU.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MPDU frame header and frame body are transmitted on the same resource with separate reliable coding for the header, then the transmission reliability of the frame header is improved, but the transmission efficiency is reduced
Solution Approach 1:
The patent divides the MPDU transmission into separate segments: frame header information and frame body information are transmitted in separate PPDUs. This segmentation allows the frame header to be transmitted with higher reliability through separate reliable coding while the frame body can use more efficient coding, thus resolving the contradiction between reliability and transmission efficiency
Solution Approach 2:
The patent introduces first information as an intermediary element that is transmitted together with the frame header. This first information indicates the correspondence between the frame header and frame body, enabling the receive end to correctly match them even though they are transmitted separately. This intermediary facilitates the separation transmission while maintaining the reliability needed for header-body matching
2Productivity
If the frame header and frame body are transmitted separately in different PPDUs, then the transmission efficiency is improved, but the complexity of matching and parsing increases
Solution Approach 1:
The first information acts as a mediator that simplifies the matching process between frame header and frame body. By including this indication information in the transmitted data, the receive end can automatically and accurately match the frame body to its corresponding frame header without complex parsing logic, thus maintaining low device complexity while enabling separate transmission
Solution Approach 2:
The first information provides feedback-like indication about the correspondence relationship between frame header and frame body. This embedded indication allows the receive end to verify and establish the correct matching relationship, reducing the complexity of the matching and parsing operations

AI summary
This application pertains to the field of communications technologies, and provides a data communication method and a related apparatus. The method includes: A transmit end separately sends generated frame header information and frame body information of an MPDU in a separation manner to a receive end. The frame header information includes a frame header, and the frame body information includes a frame body. In addition, the frame header information includes first information used to indicate the frame body corresponding to the frame header. Therefore, although the frame header is separated from the frame body, the receive end can still determine the frame body corresponding to the frame header of the MPDU, so that transmission efficiency is improved. Moreover, this is not only applicable to a single MPDU, but also applicable to an A-MPDU.
