Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing downlink data transmissions, particularly in determining the user equipment's capability to process multiple streams in parallel, which affects data rate and processing efficiency, leading to potential radio link failures.
Innovation Solution
The system allows user equipment to indicate its support for processing multiple streams in parallel, with the network configuring data transmissions accordingly based on the user equipment's capabilities, using messages like UECapabilityInformation and UEAssistanceInformation for radio resource control signaling, and adjusting data unit mapping across transport blocks and component carriers.

Engineering Contradiction Analysis
1Productivity
If the network configures multiple parallel streams for downlink data transmission, then data transmission rate is improved, but user equipment processing capability requirements increase leading to potential radio link failures
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the number of parallel streams based on UE capability parameters. The network entity receives capability information indicating whether the UE supports parallel stream processing, and accordingly configures the downlink transmission parameters (number of streams) to match the UE's processing capability, thus achieving high data rates without causing radio link failures.
2Productivity
If the user equipment indicates support for parallel stream processing, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the parallel stream processing capability configurable and adaptable. The UE can indicate its support for parallel stream processing through capability information messages, and the network can dynamically adjust the number of streams based on current conditions and UE capabilities. This allows the system to optimize for high throughput when the UE is capable, while maintaining flexibility to reduce complexity when needed.
