Operator-Specific Scrambling for Unlicensed Spectrum Data Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless network systems, user equipment cannot correctly parse data or measure channels due to the inability to identify different operators when multiple operators transmit data in the same unlicensed spectrum, leading to resource conflicts and incorrect data reception.
Innovation Solution
A data transmission method where devices generate and use scrambling code sequences based on their specific operator sequences to scramble and descramble data, ensuring that only data from the correct operator is correctly received and processed, while data from other operators is discarded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple operators transmit data in the same unlicensed spectrum, then system throughput is improved, but user equipment cannot correctly parse data or measure channels due to inability to identify different operators
Solution Approach 1:
The patent segments the data transmission by operator by introducing operator-specific scrambling code sequences. Each operator's data is scrambled with a unique sequence, allowing user equipment to identify and separate data from different operators even when transmitted simultaneously in the same unlicensed spectrum, thus maintaining data parsing accuracy while enabling multiple operators to share the spectrum.
2Productivity
If multiple operators transmit data in the same unlicensed spectrum, then resource utilization is improved, but resource conflicts occur between different operators
Solution Approach 1:
The patent introduces scrambling code sequences as an intermediary mechanism to manage resource sharing. These sequences act as identifiers that allow user equipment to distinguish between data from different operators, thereby enabling multiple operators to utilize the same unlicensed spectrum without causing harmful resource conflicts.
3Quantity of substance
If user equipment receives data from multiple operators simultaneously, then data reception capacity is improved, but measurement accuracy deteriorates due to inability to identify operators
Solution Approach 1:
The patent enables user equipment to simultaneously receive data from multiple operators by segmenting the received signal based on operator-specific scrambling code sequences. This allows the equipment to separate and independently process data from different operators, maintaining channel measurement accuracy for each operator even when receiving multiple simultaneous transmissions.
