Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently indicating and managing uplink transmission capabilities over multiple component carriers, particularly in supporting concurrent and time division multiplexed transmissions, which affects resource allocation and performance.
Innovation Solution
The method involves transmitting indications of uplink transmission capabilities, including support for concurrent or time division multiplexed transmissions across multiple component carriers, and receiving configurations for resource allocation, such as carrier switching times and antenna or transmission layer support, to optimize transmission modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation is implemented to support multiple component carriers, then uplink transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the uplink transmission capability indication into multiple independent fields: a first indication field for concurrent transmission capability and a second indication field for time division multiplexed transmission capability. Each field can be independently configured and signaled, allowing the system to activate only the necessary transmission modes based on device capabilities, thereby improving uplink performance while controlling device complexity through selective activation.
2Productivity
If concurrent transmission mode is supported across multiple component carriers, then resource allocation efficiency is improved, but difficulty of detecting and measuring capability increases
Solution Approach 1:
The patent introduces a new dimensional approach by separating capability indication into distinct fields for different transmission modes (concurrent vs. time division multiplexed) rather than using a single composite indication. This dimensional separation allows the network to clearly detect and measure each capability independently through dedicated indication fields, reducing the complexity of capability detection while improving resource allocation efficiency.
3Adaptability or versatility
If time division multiplexed transmission is supported, then adaptability to different transmission scenarios is improved, but loss of time occurs due to switching between component carriers
Solution Approach 1:
The patent implements dynamic capability indication by allowing the network to select between concurrent transmission mode and time division multiplexed transmission mode based on the indicated capabilities and current transmission requirements. The system can dynamically switch between these modes without requiring hardware changes, achieving transmission mode adaptability while minimizing time loss by selecting the most efficient mode for each scenario.

AI summary
Aspects described herein relate to transmitting an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers. In addition, a configuration to transmit over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission can be received based on the indication.
