Pseudo Access Association for Dense Wireless Channel Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dense wireless communication scenarios, multiple STAs contend for the same spectrum resource, leading to low channel use efficiency when establishing direct connections without infrastructure APs, as they must voluntarily contend for channels, which hampers system throughput.
Innovation Solution
A pseudo access method where a STA finds and establishes a pseudo access association with an AP, allowing unauthorized users to receive scheduling management, thereby preventing multiple STAs from contending for the same spectrum resource, improving channel use efficiency by enabling direct connection scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If STAs perform P2P communication without infrastructure AP, then direct connection is established, but channel use efficiency deteriorates due to voluntary contention
Solution Approach 1:
The patent introduces a pseudo-AP as an intermediary entity that mediates between contending STAs. The pseudo-AP receives contention requests from STAs, allocates channel resources, and coordinates direct connections, transforming the voluntary contention mechanism into a scheduled resource allocation system that improves channel efficiency while maintaining direct connection capability
Solution Approach 2:
The patent enables the pseudo-AP to perform multiple functions: it acts as a contention coordinator for direct connections, a resource allocator for channel access, and a scheduling entity for time-slot assignment. This multi-functional approach allows a single entity to manage both infrastructure and ad-hoc communications efficiently
2Adaptability or versatility
If multiple STAs contend for the same spectrum resource, then direct connection flexibility is maintained, but channel use efficiency deteriorates due to collisions
Solution Approach 1:
The patent implements periodic time-slot allocation where the pseudo-AP assigns specific time windows to different STA pairs for direct communication. This periodic scheduling prevents collisions by ensuring that only authorized STA pairs transmit during their allocated slots, thereby improving channel efficiency while preserving connection flexibility
Solution Approach 2:
The patent employs preliminary resource allocation where the pseudo-AP pre-assigns channel resources and time slots to STA pairs before direct communication begins. This advance planning eliminates contention collisions by ensuring that STAs have predetermined access rights, thus improving channel efficiency without sacrificing adaptability

AI summary
Embodiments of the present invention disclose a pseudo access method, a direct connection scheduling method for pseudo access, a station, and an access point, so as to improve channel use efficiency for communication between STAs in a dense scenario. The method in the embodiments of the present invention includes: after finding an AP supporting pseudo access, sending, by a STA, pseudo access information to the AP, and establishing a pseudo access association with the AP, so that a STA that is not an authorized user of the AP can perform pseudo access to the AP, and accept scheduling management by the AP.
