Wireless Frame Presence Indication for Multi-Link Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing and transmitting beacon and other frames, particularly in multi-link wireless networks where coordination of transmission information and parameters across different links is complex.
Innovation Solution
The method involves outputting a first frame that indicates the presence and attributes of subsequent second frames, which can include transmission information and parameters specific to each link, allowing for coordinated communication across multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beacon frames are transmitted periodically on multiple links to ensure reliable communication, then network reliability is improved, but transmission overhead and channel occupancy increase
Solution Approach 1:
The beacon information is segmented into two parts: essential beacon data transmitted periodically, and supplementary information transmitted aperiodically in response to specific requests. This segmentation allows the system to maintain reliable communication while reducing overall transmission overhead by only sending additional information when needed.
Solution Approach 2:
The patent implements periodic beacon transmissions combined with event-driven supplementary transmissions. The periodic beacon frames maintain basic communication reliability, while aperiodic transmissions occur only when specific conditions are met (such as when a station requests additional information), thereby reducing energy waste from unnecessary transmissions.
2Loss of information
If multiple beacon frames are transmitted to convey comprehensive network information, then information completeness is improved, but channel occupancy and transmission time increase
Solution Approach 1:
The patent extracts only the essential beacon information into periodic transmissions, while supplementary information is extracted and transmitted separately on-demand. This extraction approach ensures that critical information is always conveyed while avoiding the time penalty of transmitting all possible information in every beacon frame.
Solution Approach 2:
The patent prepares beacon information in advance by identifying which information is essential versus supplementary. Essential information is pre-packaged for periodic transmission, while supplementary information is prepared for on-demand transmission only when requested, optimizing the timing and efficiency of information delivery.
3Speed
If beacon frame transmission intervals are shortened to improve network responsiveness, then network responsiveness is improved, but energy consumption and transmission overhead increase
Solution Approach 1:
The patent uses extended periodic intervals for essential beacon transmissions to reduce energy consumption, while maintaining network responsiveness through on-demand supplementary transmissions. When stations need additional information, they can request it immediately without waiting for the next periodic beacon, thus achieving both energy efficiency and responsiveness.
Solution Approach 2:
The patent implements a feedback mechanism where stations can request supplementary beacon information when needed. This feedback loop allows the network to respond to actual information needs rather than following a rigid schedule, improving responsiveness without requiring continuous periodic transmissions at high frequency.
Data Source
AI summary
This disclosure provides a method for wireless communication performable at an access point (AP). The AP transmits a first frame to a non-AP wireless station (STA). A first field of the first frame indicates transmission information associated with one or more second frames. A second field of the first frame contains a first set of parameters associated with the AP. The AP further transmits a second frame to the non-AP wireless STA. The second frame may include at least one field containing a second set of parameters associated with the AP. The first set of parameters are different from the second set of parameters.
