Link Identifier Indication for Multi-Link Wireless Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-link wireless communication devices, the high signaling overheads for indicating links lead to inefficiencies in data transmission, as sending on one link can affect receiving on another, necessitating accurate determination of links to improve communication efficiency.
Innovation Solution
A method involving the use of link identifiers and transceive capability indications in radio frames to reduce signaling overheads, where link information is associated with a link identifier, and multi-link operating capability fields indicate simultaneous transceiving capabilities among multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-link devices work on a large quantity of links to ensure communication quality, then communication reliability is improved, but signaling overheads for indicating links increase
Solution Approach 1:
The patent uses link identifier indication to create a simplified representation (copy) of link information. Instead of transmitting complete link details, the system uses compact link identifiers that reference pre-defined link configurations, significantly reducing signaling overhead while maintaining the ability to identify and manage multiple links for reliable communication
Solution Approach 2:
The patent segments link information into two parts: link identifiers (compact references) and link configurations (detailed parameters). This segmentation allows the system to transmit only the necessary identifier information in signaling, while the full link configurations are maintained separately, reducing the overhead associated with indicating multiple links
2Measurement precision
If link information is explicitly indicated for each link, then link identification accuracy is improved, but data transmission efficiency deteriorates due to high signaling overheads
Solution Approach 1:
The patent creates compact link identifier representations that accurately reference complete link configurations. These identifier copies maintain sufficient information for accurate link identification while occupying minimal signaling space, thus preserving identification accuracy without sacrificing transmission efficiency
Solution Approach 2:
The patent performs preliminary setup by pre-defining link configurations and assigning link identifiers beforehand. This preliminary action allows the system to reference pre-configured links using compact identifiers during data transmission, eliminating the need to repeatedly transmit full link information and thereby improving transmission efficiency while maintaining identification accuracy

AI summary
A link identifier indication method includes: A multi-link device working on a plurality of links sends a radio frame, where the radio frame includes link information of at least one link in the plurality of links, and link information of one link is used to indicate the link and corresponds to a link identifier of the link; a receiving device that receives the radio frame may determine the link identifier of the link corresponding to the link information, so that in communication of the multi-link device, a link can be identified by using the link identifier.
