WLAN Uplink Collision Control via Base Station Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WLAN networks, the probability of uplink data collisions increases due to random backoff time selection by user equipment, leading to reduced system capacity and compromised service quality, especially when multiple devices contend for resources.
Innovation Solution
Implementing a method where user equipment receives indication information from a base station to stop or continue uplink data transmission through a WLAN access point, using service identifier information to manage transmission, thereby reducing data volume and collision probability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user equipment uses random backoff time selection to contend for uplink data transmission resources in WLAN network, then ease of operation is improved, but uplink data collision probability increases
Solution Approach 1:
The base station monitors WLAN channel status and provides feedback to user equipment in the form of indication information, instructing whether to perform uplink data transmission. This feedback mechanism allows the system to adapt to changing channel conditions and avoid collisions by coordinating transmission decisions across multiple user equipment devices.
Solution Approach 2:
The base station acts as an intermediary between user equipment and the WLAN network. It receives channel status information, processes it, and generates indication information that mediates the transmission decisions of user equipment, thereby reducing collision probability while maintaining ease of operation.
2Productivity
If multiple user equipment devices contend for uplink data transmission in WLAN network, then system capacity is improved, but uplink data collision probability increases
Solution Approach 1:
The base station provides centralized feedback to multiple user equipment devices, coordinating their transmission decisions based on overall WLAN channel conditions. This allows the system to maintain high capacity by allowing multiple devices to transmit while reducing collision probability through coordinated access control.
Solution Approach 2:
The system dynamically adjusts transmission permissions for each user equipment device based on real-time channel conditions. The base station generates indication information that dynamically controls which devices can transmit at any given moment, optimizing both system capacity and collision avoidance.
3Productivity
If user equipment transmits uplink data through WLAN access point, then productivity is improved, but service quality deteriorates due to collisions
Solution Approach 1:
The base station provides feedback control by sending indication information to user equipment, enabling the system to maintain high productivity through WLAN transmission while ensuring service quality by preventing collisions through coordinated access management.

AI summary
Embodiments of the present invention provide a data transmission method, user equipment, and a base station. The method can include receiving, by user equipment, indication information for stopping transmission sent by a base station, where the indication information for stopping transmission is configured to instruct the user equipment to stop transmitting uplink data for at least one service by through an access point AP of a wireless local area network WLAN. The method can also include stopping, by the user equipment according to the indication information for stopping transmission, transmitting the uplink data for the at least one service through the AP. In this process, the user equipment reduces a data volume of uplink data transmitted through the WLAN, so as to decrease a probability that an uplink data collision occurs in the WLAN, thereby improving service quality.
