Uplink Data Offload Transmission via Base Station Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, uplink data transmission on supplementary networks often experiences collisions and retransmissions due to poor data transmission quality, leading to increased transmission time delays, especially for data with higher Quality of Service (QoS) requirements.
Innovation Solution
A data offload transmission method where a base station obtains transmission performance parameters, such as data transmission time delay and signal quality, and configures user transmission restrictions to prevent collisions by either stopping data transmission or reducing data segment length when thresholds are exceeded, thereby improving data transmission efficiency.

Engineering Contradiction Analysis
1Ease of operation
If user equipment performs uplink data transmission on supplementary network using DCF competitive mechanism, then data transmission can be initiated when channel is idle, but multiple user equipment transmissions may collide at the same moment causing base station to fail receiving any data
Solution Approach 1:
The base station performs preliminary actions by obtaining transmission performance parameters, configuring user transmission restrictions based on these parameters, and sending the restrictions to user equipment before data transmission occurs. This preliminary configuration prevents collisions by controlling when and how user equipment transmits, thereby improving data reception success rate while maintaining transmission initiation capability
Solution Approach 2:
The system implements feedback by continuously monitoring transmission performance parameters (time delay and signal quality) and adjusting user transmission restrictions accordingly. When performance degrades below thresholds, the base station configures restrictions to stop or reduce transmission, preventing collisions and improving overall reliability of data transmission
2Productivity
If collision occurs and retransmission is performed in competitive manner, then data can be resent, but collision may happen again increasing transmission time delay for high QoS data
Solution Approach 1:
The base station configures user transmission restrictions in advance based on transmission performance parameters, preventing collisions before they occur. This eliminates the need for repeated competitive retransmissions and reduces transmission time delay for high QoS data by ensuring successful transmission attempts from the outset
Solution Approach 2:
The system uses feedback on transmission performance (time delay and signal quality thresholds) to dynamically adjust transmission restrictions. When performance deteriorates, the base station configures restrictions to stop or reduce transmission, preventing further collisions and reducing overall transmission time delay
3Reliability
If base station configures user transmission restriction to stop data transmission when time delay exceeds threshold 1 or RSSI lower than threshold 1, then collision is avoided, but data transmission is completely halted even when partial transmission might be beneficial
Solution Approach 1:
The system dynamically adjusts transmission restrictions based on real-time transmission performance parameters. Instead of static stop/go decisions, the base station configures flexible restrictions that can stop transmission when performance is poor (avoiding collisions) while allowing transmission when performance is acceptable (maintaining throughput). The thresholds and restriction levels are adapted dynamically to current channel conditions
Solution Approach 2:
The system changes operational parameters (transmission restriction levels) based on transmission performance parameters (time delay and RSSI thresholds). When time delay exceeds threshold 1 or RSSI drops below threshold 1, the system changes the transmission state to stopped; when time delay exceeds threshold 2 or RSSI drops below threshold 2 but not the stricter thresholds, the system adjusts segment length. This parameter-based control balances collision avoidance with maintaining data transmission throughput
