Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in accessing and maintaining high-frequency radio frequency links such as 3.5 GHz, 45 GHz, or 60 GHz due to access constraints and propagation losses, which limits throughput and system capacity.
Innovation Solution
Utilizing a lower-frequency anchor link (e.g., 2.4 GHz, 5 GHz, or 6 GHz) to facilitate communication with higher-frequency links by exchanging identifying and control information, enabling conditional setup and management of higher-frequency links through reduced neighbor reports and multi-link probe responses.

Engineering Contradiction Analysis
1Productivity
If high-frequency radio frequency links (3.5 GHz, 45 GHz, or 60 GHz) are used for wireless communication, then data rates and system capacity are improved, but access constraints and propagation losses increase
Solution Approach 1:
The patent introduces a lower-frequency anchor link as an intermediary to facilitate communication and coordination for high-frequency links. The anchor link exchanges identifying information and control information, enabling conditional setup and management of high-frequency links while mitigating their reliability issues through reduced signaling overhead and better propagation characteristics.
2Productivity
If high-frequency radio frequency links (3.5 GHz, 45 GHz, or 60 GHz) are used for wireless communication, then system capacity is improved, but propagation losses increase
Solution Approach 1:
The lower-frequency anchor link serves as a mediator that enables high-frequency link operations with reduced energy loss. By handling identification and control signaling through the anchor link, the system minimizes the number of high-frequency transmissions required, thereby reducing overall propagation losses while maintaining high system capacity.
3Reliability
If lower-frequency anchor link is used to facilitate high-frequency link communication, then access reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential identifying information and control information needed for high-frequency link management and transfers it through the anchor link. This selective extraction approach enables reliable anchor link utilization while minimizing signaling overhead by transmitting only critical data rather than complete communication streams.

AI summary
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for high frequency multi-link support systems operation. In some aspects, an access point (AP) multi-link device (MLD) and a non-AP MLD may use a first radio frequency link to support and facilitate communications using a second radio frequency link, where such a second radio frequency link may otherwise be associated with access constraints or difficulties. For example, the first radio frequency link may be a sub-7 gigahertz (GHz) link and the second radio frequency link may be a 3.5 GHz, 45 GHz, or 60 GHz link. The AP MLD may transmit, to the non-AP MLD via the first radio frequency link, identifying and control information associated with the second radio frequency link. The non-AP MLD and the AP MLD may use the identifying and control information to communicate data via the second radio frequency link.
