Trigger-Based Random Access Allocation in Multi-BSSID Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in efficiently allocating resource units (RUs) across multiple basic service sets (BSSs) within a wireless local area network (WLAN), leading to inefficient use of wireless resources and potential disparities in access among different BSSs.
Innovation Solution
The implementation of a system that allows an access point (AP) to prioritize the allocation of random RUs to each BSS based on various factors such as the number of associated stations, traffic types, priority levels, security parameters, and quality of service (QoS) parameters, ensuring fair and efficient resource distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If random RUs are allocated to all BSSs equally, then resource distribution appears simple and fair, but wireless resource utilization becomes inefficient and access disparities occur among BSSs with different loads
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on individual BSS characteristics. Each BSS receives random RUs according to its specific needs and load conditions rather than uniform allocation. The AP monitors per-BSS metrics (number of associated STAs, traffic types, QoS parameters) and adjusts RU allocation accordingly, making the allocation policy adaptive to local conditions of each BSS.
Solution Approach 2:
The patent implements dynamic resource allocation where the AP continuously adjusts random RU allocation to each BSS based on changing network conditions. The allocation is not static but adapts in real-time to factors such as varying numbers of associated STAs, changing traffic types, and fluctuating QoS requirements. This dynamic approach optimizes wireless resource utilization while maintaining fairness among BSSs with different loads.
2Productivity
If resource allocation is prioritized based on multiple factors (number of STAs, traffic types, QoS parameters), then resource distribution efficiency improves, but the complexity of allocation decisions increases
Solution Approach 1:
The patent employs feedback mechanisms where the AP continuously monitors various BSS parameters (number of associated STAs, traffic types, QoS parameters, security parameters) and uses this feedback information to make informed resource allocation decisions. The AP adjusts random RU allocation based on the collected feedback, creating a closed-loop system that optimizes resource distribution efficiency while systematically managing the complexity of allocation decisions through data-driven policies.
3Ease of operation
If all BSSs compete for random RUs simultaneously, then resource allocation appears fair, but access disparities occur among BSSs with different numbers of associated stations
Solution Approach 1:
The patent changes the allocation parameter from uniform random distribution to differentiated distribution based on multiple BSS-specific parameters. The AP considers the number of associated STAs, traffic types, priority levels, security parameters, and QoS requirements to adjust the probability and quantity of random RU allocation to each BSS. This parameter-based differentiation ensures both fairness (BSSs with more STAs get more resources) and efficiency (resources match actual network needs).

AI summary
This disclosure provides systems, methods, and apparatuses for allocating wireless resources to a multiple basic service set identifier (BSSID) set including a number of BSSIDs each associated with a corresponding one of a number of access points (APs). An AP may allocate random access resources for use by stations belonging to the multiple BSSID set using a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element. The AP may transmit a trigger frame containing the number of AID values to the stations belonging to the multiple BSSID set.
