Solution Overview
Problem
Current wireless communication technologies face challenges in managing multi-link communication across multiple frequency bands, particularly in supporting low-latency transmission and efficient spectrum utilization in scenarios like video transmission and augmented/virtual reality applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-link communication is implemented across multiple frequency bands, then spectrum utilization and transmission rate are improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent segments the multi-link communication management by introducing a Reduced Neighbor Report (RNR) element that is selectively included in beacon frames only when specific conditions are met. This segmentation approach divides the communication management into conditional scenarios, reducing the overall coordination overhead while maintaining multi-link productivity.
Solution Approach 2:
The patent changes the parameter of beacon frame content by conditionally including or excluding the RNR element based on execution primitives and neighbor AP conditions. This parameter change allows the system to adapt the level of detail in communication coordination, optimizing the balance between transmission rate and coordination overhead.
2Productivity
If reduced neighbor report element is conditionally included in beacon frames, then communication efficiency is improved, but measurement precision of neighbor AP information may be compromised
Solution Approach 1:
The patent applies partial action by including the RNR element only when specific conditions are satisfied, rather than always including it. This partial inclusion strategy improves communication efficiency by reducing unnecessary beacon frame overhead while maintaining sufficient neighbor AP information accuracy for the given conditions.
Solution Approach 2:
The patent changes the parameter of information completeness in beacon frames based on execution primitives. When the execution primitive indicates reduced measurement requirements, the RNR element is conditionally included, achieving a parameter-based balance between communication efficiency and measurement precision.
3Loss of time
If multi-link devices coordinate beacon frames across multiple links, then low-latency transmission is achieved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by establishing execution primitives and conditional rules in advance for RNR element inclusion. This preliminary configuration enables low-latency transmission during actual multi-link operations without requiring complex real-time coordination decisions, thus reducing device complexity while maintaining low latency.
Solution Approach 2:
The patent uses parameter changes in the execution primitive to control the level of coordination required. By changing the execution primitive parameter, the system can switch between different coordination modes, achieving low-latency transmission with simplified coordination mechanisms appropriate for each scenario.

AI summary
A communication method is performed by an access point (AP) supporting multi-link (ML) communication, and includes: determining a first message frame, wherein the first message frame includes a reduced neighbor report (RNR) element in response to a condition related to ML communication being satisfied; and sending the first message frame on a first link among multiple links.
