Non-AP MLD Operation Mode Transition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition between different operation modes in wireless communication systems, such as those supported by non-AP MLDs, is often time-consuming and inefficient, leading to performance degradation, especially when frequent transitions are required.
Innovation Solution
A method where a non-AP MLD transits to a target operation mode by sending a notification in a single management frame, carrying necessary information in a subfield, without requiring additional management frames, thereby simplifying the transition process and reducing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple-step transition is used for operation mode changes, then transition control is thorough and reliable, but transition time increases and system performance degrades
Solution Approach 1:
The patent merges the operation mode notification and the mode transition into a single step process. The non-AP MLD transits to the target operation mode directly after sending the notification, combining what would traditionally be separate notification and transition steps into one unified operation, thereby reducing transition time while maintaining control reliability
Solution Approach 2:
The non-AP MLD prepares and sends the operation mode notification frame in advance, containing all necessary information about the target operation mode. This preliminary action allows the AP MLD to be ready for the transition, and the actual transition occurs immediately after notification without requiring additional intermediate steps, thus reducing overall transition time
2Measurement precision
If multiple management frames are exchanged for mode transition, then transition information is complete and accurate, but communication overhead increases
Solution Approach 1:
The operation mode notification frame serves multiple functions simultaneously: it notifies the AP MLD of the intended mode change, carries complete transition information (including target mode type and related parameters), and triggers the actual transition. This multi-functional frame eliminates the need for separate frames for each purpose, reducing communication overhead while maintaining information completeness
Solution Approach 2:
The patent extracts all necessary transition information into a single notification frame structure. By consolidating what would traditionally be distributed across multiple frames into one comprehensive notification, the system reduces the total number of frames exchanged while ensuring all required information is transmitted accurately
3Adaptability or versatility
If frequent operation mode transitions are performed, then system adapts to changing user scenarios, but cumulative overhead and time loss increase
Solution Approach 1:
The system enables dynamic operation mode transitions allowing the non-AP MLD to adapt to changing user scenarios by switching between different operation modes (STR, NSTR, MLSR, EMLSR). The simplified single-step transition mechanism allows frequent adaptations without the cumulative overhead penalty of traditional multi-step processes, thus maintaining high system throughput even with frequent mode changes

AI summary
A method for performing operation mode transition control in a wireless communication system and associated apparatus are provided, where a non-access-point multi-link device (non-AP MLD) is wirelessly linking to a first access point multi-link device (AP MLD). The method includes: transmitting, by the non-AP MLD, a first operation mode notification in a first management frame to the first AP MLD, for a first target operation mode to which the non-AP MLD is going to transit, carrying at least information regarding the first target operation mode, wherein the information is carried in at least one subfield of the first operation mode notification; and transiting, by the non-AP MLD, to the first target operation mode without transmitting additional management information regarding the first target operation mode to the first AP MLD.
