Engineering Contradiction Analysis
1Productivity
If multiple communication links are utilized to enhance data throughput, then data transmission rate is improved, but system complexity increases
Solution Approach 1:
The system segments communication resources by dividing multiple communication links into distinct communication groups, where each group contains a subset of links. This segmentation allows independent management and control of different link groups, reducing overall system complexity while maintaining high throughput capabilities through parallel operation of multiple groups.
Solution Approach 2:
The system dynamically switches between different communication groups based on channel conditions, traffic requirements, and interference levels. This dynamic adaptation enables the system to optimize performance by activating only the necessary number of links at any given time, thereby improving throughput while managing complexity through selective activation rather than permanent full-utilization of all links.
2Reliability
If multiple communication links are used to improve reliability, then communication reliability is enhanced, but device complexity increases
Solution Approach 1:
The system merges multiple communication links into unified communication groups that can be managed as single entities. By combining links within each group and implementing group-level control mechanisms, the system achieves diversity gain and improved reliability through multiple paths while reducing device complexity through consolidated management structures rather than individual link management.
Solution Approach 2:
The system changes operational parameters by switching between different communication groups with varying configurations of links, frequencies, and modulation schemes. This parameter variation enables the system to adapt to changing channel conditions and maintain reliable communication through diversity while managing complexity through parameter optimization rather than structural expansion.
3Productivity
If channel bonding and MIMO schemes are implemented across multiple links, then data transmission capability is enhanced, but interference management difficulty increases
Solution Approach 1:
The system introduces communication groups as intermediary structures between individual links and the overall system. These groups act as mediators that aggregate interference characteristics from multiple links within each group, enabling simplified interference management at the group level while still utilizing channel bonding and MIMO techniques within groups to enhance data transmission capability.

AI summary
For example, a non-AP MLD may determine whether an EMLSR enablement criterion is met. For example, the EMLSR enablement criterion may be based on one or more predefined enablement criteria corresponding to one or more enablement-criteria parameters. For example, the non-AP MLD may activate operation of the non-AP MLD at an EMLSR operation mode of an MLO over a plurality of links with an AP MLD based on a determination that the EMLSR enablement criterion is met. For example, the non-AP MLD may determine whether an EMLSR disablement criterion is met during the EMLSR operation mode. For example, the EMLSR disablement criterion may be based on one or more predefined disablement criteria corresponding to one or more disablement-criteria parameters. For example, the non-AP MLD may switch the non-AP MLD from the EMLSR operation mode to a non-EMLSR MLO mode based on a determination that the EMLSR disablement criterion is met.
