Uplink Data Compression Buffer Reset for Wireless Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, uplink data compression faces challenges due to limited high-frequency band and wide bandwidth usage by terminals, leading to bottlenecks in transmission resources and reduced coverage compared to downlink transmission, necessitating efficient resource utilization.
Innovation Solution
The implementation of an uplink data compression (UDC) method that involves data compression at the terminal and decompression at the base station, using techniques like DEFLATE-based algorithms and specific header formats to enhance data transmission efficiency and prevent decompression failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink data compression is implemented to improve transmission resource utilization, then data transmission efficiency is improved, but data loss may occur due to decompression failures
Solution Approach 1:
The patent applies preliminary action by resetting the compression buffer before data compression and setting a reset indicator in the compressed data packet. This preliminary marking allows the base station to proactively identify and handle potential decompression failures before they propagate, thereby maintaining both compression efficiency and data reliability.
Solution Approach 2:
The patent implements feedback mechanisms through acknowledgments between terminal and base station regarding compression buffer reset status. The base station feeds back whether decompression was successful, allowing the terminal to adjust its compression strategy accordingly, thus resolving the contradiction between compression efficiency and data integrity.
2Productivity
If compression buffer is continuously updated to maintain compression efficiency, then productivity is improved, but data loss occurs when intermediate data is discarded
Solution Approach 1:
The patent applies preliminary action by resetting the compression buffer before data compression and setting a reset indicator in the compressed data packet. This preliminary marking allows the base station to proactively identify and handle potential decompression failures before they propagate, thereby maintaining both compression efficiency and data reliability.
Solution Approach 2:
The patent implements a mechanism where intermediate compression buffer data is deliberately discarded when reset conditions are met, and the system recovers by resetting the buffer and notifying the base station. This controlled discarding prevents data loss propagation while maintaining overall compression efficiency.
3Speed
If uplink transmission uses high frequency bands to increase data rates, then transmission speed is improved, but coverage is reduced due to propagation loss
Solution Approach 1:
The patent applies parameter changes by implementing data compression at the terminal before transmission. This reduces the amount of data that needs to be transmitted over the high-frequency channel, effectively compensating for the reduced coverage area by making more efficient use of the available high-speed transmission resources.
