Wireless Terminal Data Rate Comparison for Decoding Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G communication system, there is a mismatch between the data rate supported by a terminal and the data rate determined for data transmission, leading to inefficiencies in data decoding and transmission.
Innovation Solution
A method is implemented where a terminal receives downlink control information to determine the number of transport blocks allocated in a slot and compares this with its maximum data rate, deciding whether to decode data based on this comparison, ensuring that data transmission does not exceed the terminal's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the data rate is increased to meet high data traffic demand, then the transmission speed is improved, but the terminal may not be able to decode the data correctly
Solution Approach 1:
The patent applies dynamics by making the transport block size adjustable rather than fixed. The base station dynamically determines the transport block size based on real-time feedback about the terminal's actual data rate capability, allowing the system to adapt between high speed and high reliability modes as needed
Solution Approach 2:
The patent implements feedback through the terminal reporting its actual data rate capability to the base station. This feedback mechanism enables the base station to adjust the transport block size to match the terminal's true capacity, preventing decoding failures while maximizing transmission speed
2Productivity
If the transport block size is increased to improve transmission efficiency, then the productivity is improved, but the terminal decoding capability is overwhelmed
Solution Approach 1:
The patent changes the parameter of transport block size based on the terminal's actual data rate capability. By adjusting this critical parameter dynamically, the system optimizes transmission efficiency while ensuring the terminal can successfully decode the data
Solution Approach 2:
The terminal performs preliminary action by reporting its data rate capability to the base station before data transmission begins. This advance information allows the base station to pre-determine an appropriate transport block size that matches the terminal's decoding capability
3Device complexity
If the data rate is determined based on allocated resources without considering terminal capability, then the device complexity is reduced, but the loss of information increases
Solution Approach 1:
The terminal performs self-service by autonomously determining and reporting its data rate capability to the base station. This self-reporting mechanism simplifies the overall system complexity while preventing information loss through decoding failures
