Wireless Station Capabilities Element Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of wireless communication standards, such as IEEE 802.11ay, results in cumbersome capabilities elements that either need to be omitted from beacons to reduce transmission time or consume significant bandwidth when included, complicating the process of establishing wireless connections.
Innovation Solution
A method and system for establishing wireless connections by generating a capabilities element with a core set of capabilities in a fixed format and an extended set in an extensible format, allowing each device to signal its capabilities efficiently, balancing information completeness with reduced bandwidth consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If capabilities elements are included in beacon frames, then complete capability information is provided for connection establishment, but beacon transmission time increases and bandwidth is consumed
Solution Approach 1:
The patent segments capability information into two distinct parts: a compressed capability information field included in beacon frames, and a full capabilities element exchanged separately during connection establishment. This segmentation allows beacons to remain concise while complete capability information is still available when needed, resolving the contradiction between information completeness and transmission time.
2Loss of information
If capabilities elements are included in beacon frames, then complete capability information is provided, but bandwidth consumption increases
Solution Approach 1:
By dividing capability information into a compressed summary for beacons and a full detailed element for connection establishment, the patent reduces bandwidth consumption in frequent beacon transmissions while ensuring complete capability information is exchanged during the less frequent connection establishment process.
Solution Approach 2:
The patent applies partial action by including only compressed capability information in beacons rather than the full capabilities element. This partial inclusion reduces bandwidth consumption while still providing sufficient information for basic device identification and capability overview, with the understanding that complete information exchange occurs during connection establishment.
3Loss of time
If capabilities elements are omitted from beacons, then transmission time is reduced, but additional frames are required to exchange capability information
Solution Approach 1:
The patent performs preliminary action by including compressed capability information in beacon frames before connection establishment. This preliminary provision of capability information allows devices to perform basic compatibility checks and filtering earlier in the process, reducing the need for additional capability exchange frames and simplifying the overall connection establishment procedure.

AI summary
A method in a first wireless station of establishing a connection with a second wireless station includes: generating a frame including a capabilities element having: a core capabilities field containing a predefined sequence of core subfields having respective predefined lengths; the core subfields containing respective first core values defining core capabilities of the first wireless station; and at least one extended capability field containing: an extended capability identifier subfield containing an identifier of one of a plurality of predefined extended capabilities; an extended capability length subfield containing an extended capability length value; and an extended capability payload subfield having a length equal to the extended capability length value; the payload subfield containing a first extended value defining an extended capability of the first wireless station; and responsive to generating the frame, transmitting the frame.
