Conditioned Multi-Link Operation for mmWave Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing and optimizing communication over millimeter Wave (mmWave) links, particularly in terms of power consumption and complexity, as mmWave communication often requires higher power and more complex interfaces compared to sub-10 GHz bands.
Innovation Solution
The implementation of a Multi-Link Operation (MLO) mechanism that allows for conditioned communication over mmWave links, where the system can reuse components from sub-10 GHz bands, and selectively restricts mmWave usage based on conditions such as power consumption, data size, latency, and access categories, to reduce complexity and power usage.

Engineering Contradiction Analysis
1Productivity
If mmWave communication is used to achieve higher data rates and capacity, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic communication mode selection that adapts between mmWave and sub-10 GHz bands based on real-time conditions. The system dynamically switches communication modes to optimize the trade-off between data rate and power consumption, using mmWave when high performance is needed and sub-10 GHz when power savings are prioritized.
Solution Approach 2:
The system applies partial use of mmWave communication by selectively activating it only when specific conditions are met (e.g., when high data rates are required and channel conditions are favorable). Rather than continuously using mmWave, the system employs it partially and conditionally to achieve performance improvements without sustained high power consumption.
2Productivity
If mmWave communication interface is implemented to enable high-speed wireless communication, then communication capability is improved, but device complexity increases
Solution Approach 1:
The patent creates a unified communication system that can operate across multiple frequency bands (both mmWave and sub-10 GHz) using a common architectural framework. The same communication interface and protocol stack handle both bands, making the system multi-functional without requiring separate dedicated interfaces for each band, thus reducing overall complexity.
Solution Approach 2:
The system introduces a band selection mechanism and conditional communication framework that acts as an intermediary between the application layer and the physical communication interfaces. This mediator manages the complexity by abstracting the differences between mmWave and sub-10 GHz interfaces, allowing higher-layer protocols to operate uniformly regardless of the underlying band being used.
3Use of energy by moving object
If conditional communication restrictions are applied to limit mmWave usage, then power consumption is reduced, but communication flexibility decreases
Solution Approach 1:
The communication restrictions are implemented dynamically rather than statically. The system continuously evaluates channel conditions, device state, and application requirements to adaptively adjust mmWave usage conditions. This dynamic approach maintains flexibility by allowing the system to override or relax restrictions when conditions warrant, while still achieving power savings during normal operation.
Solution Approach 2:
The system employs feedback mechanisms that monitor communication performance, power consumption, and channel conditions to continuously refine the conditions for mmWave usage. This feedback loop ensures that flexibility is preserved by learning from actual system behavior and adjusting restrictions optimally, preventing overly conservative limitations while maintaining power efficiency.

AI summary
For example, a non Access Point (AP) (non-AP) Multi-Link Device (MLD) may be configured to set at least one millimeter Wave (mmWave) link usage condition field to indicate mmWave link usage condition information for Multi-Link (ML) Operation (MLO) over an mmWave link and a sub 10 Gigahertz (GHz) (sub-10 GHz) link with an AP MLD. For example, the mmWave link usage condition information may be configured to indicate one or more conditions for the AP MLD to use the mmWave link to transmit one or more transmissions to the non-AP MLD. For example, the non-AP MLD may be configured to transmit a frame, which includes the at least one mmWave link usage condition field, for example, to the AP MLD.
