Solution Overview

Problem

In wireless communication systems, particularly in IEEE 802.11 standards, the size limit of Beacon frames and management frames restricts the inclusion of all non-transmitted BSSID profiles and neighbor reports, making it difficult for station devices to obtain complete information about associated BSSs, leading to incomplete data transmission.

Innovation Solution

A BSS information spreading indication system that allows a transmitted BSSID AP to indicate the number of beacon intervals, ensuring that all non-transmitted BSSID profiles and neighbor reports are included in subsequent Beacon frames, with a pattern of inclusion based on the indicated intervals, and provides mechanisms for probe responses to indicate missing information and suppress unnecessary transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all non-transmitted BSSID profiles and neighbor reports are included in a single Beacon frame, then complete BSS information is provided to station devices, but the frame size exceeds the maximum limit of management frames

Engineering Contradiction:
Improvecompleteness of BSS informationVSAvoidframe size
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent segments the BSS information by introducing a BSS information spreading indication mechanism that divides the inclusion of non-transmitted BSSID profiles and neighbor reports across multiple beacon intervals. Instead of attempting to include all information in a single frame, the system spreads the information distribution over time, with each beacon frame containing a subset of the complete BSS information based on the indicated spreading pattern.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If BSS information is spread over multiple beacon intervals, then frame size limits are respected, but station devices experience increased uncertainty and may not receive complete information within a reasonable time

Engineering Contradiction:
Improveframe size complianceVSAvoidinformation acquisition time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent applies preliminary action by including a BSS information spreading indication in the beacon frame that预先 informs station devices about the pattern and duration of information distribution. This indication allows STAs to anticipate when complete information will be available and to adjust their reception behavior accordingly, reducing uncertainty and enabling more efficient information acquisition despite the multi-interval spreading.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by providing STAs with information about the spreading pattern through the beacon indication, allowing devices to monitor and track the distribution of BSS information over time. This feedback mechanism enables STAs to determine when they have received complete information or when to continue monitoring for additional updates.

Inventive Principle:
Principle #23Feedback

3Reliability

If beacon frames transmit complete BSS information frequently, then station devices can maintain up-to-date information, but wireless channel overhead and energy consumption increase

Engineering Contradiction:
Improveinformation freshnessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by spreading BSS information distribution across multiple beacon intervals rather than transmitting complete information in every frame. The BSS information spreading indication establishes a periodic pattern that allows the system to maintain information freshness over time while reducing the frequency and volume of transmissions, thereby lowering energy consumption and channel overhead compared to frequent complete information transmissions.

Inventive Principle:
Principle #19Periodic action

AI summary

This disclosure describes systems, methods, and devices related to basic service set (BSS) information spreading indication. A device may determine one or more collocated access points (APs). The device may determine a target beacon transmission time (TBTT) associated with a beacon interval. The device may determine a first beacon frame comprising a first multiple basic service set identification (BSSID) element. The device may determine a second beacon frame comprising a second multiple BSSID element. The device may determine a time period associated with the first beacon frame and the second beacon frame. The device may cause to send the first beacon frame at a first time to one or more station devices. The device may cause to send the second beacon frame at a second time to the one or more station devices.
