Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the NR system, configuring beam information for component carriers (CCs) in different transmission modes leads to significant signaling overhead due to the need for separate beam configurations for each mode, which complicates communication efficiency.
Innovation Solution
A method and apparatus that allows a terminal device to receive and a network device to transmit first information configuring beam information applicable to multiple CCs supporting various transmission modes, enabling a common beam indication across these CCs through a single signaling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate beam configurations are used for each transmission mode, then beam information can be accurately configured for each mode, but signaling overhead becomes significant
Solution Approach 1:
The patent applies universality by designing a unified beam information configuration method that works across multiple transmission modes (sTRP, sDCI-mTRP, mDCI-mTRP). The network device configures beam information once that is then applicable to all CCs regardless of their transmission mode, making the configuration mechanism multi-functional and eliminating the need for separate configurations for each mode.
Solution Approach 2:
The patent merges the beam configuration process by combining multiple separate configuration operations into a single unified configuration. Instead of configuring beam information separately for each transmission mode and each CC, the network device performs one configuration operation that simultaneously applies to all CCs, thereby reducing signaling overhead while maintaining configuration accuracy.
2Reliability
If separate beam configurations are used for each transmission mode, then each mode can be optimized, but beam indication delay increases
Solution Approach 1:
The patent applies preliminary action by configuring beam information in advance in a unified manner before actual transmission occurs. The network device performs the beam configuration operation once ahead of time, and this pre-configured information is then available for all CCs and transmission modes, eliminating the need for repeated configuration operations and reducing beam indication delay.
Solution Approach 2:
The patent merges multiple beam indication operations into a single unified indication mechanism. By combining the configuration and indication processes for different transmission modes into one operation, the system reduces the cumulative time required for beam indication while still maintaining optimization for each specific transmission mode through the unified configuration approach.
3Adaptability or versatility
If multiple beam configurations are used, then comprehensive beam control is achieved, but device complexity increases
Solution Approach 1:
The patent applies universality by creating a single configuration mechanism that serves multiple transmission modes. The network device uses one unified configuration operation that can adapt to and control beam information for all CCs regardless of whether they operate in sTRP, sDCI-mTRP, or mDCI-mTRP modes, thereby reducing configuration mechanism complexity while maintaining comprehensive beam control flexibility.
Solution Approach 2:
The patent applies parameter changes by using a unified configuration approach where the network device modifies beam information parameters in a single operation that affects all CCs. This approach maintains adaptability and versatility across different transmission modes by allowing the system to adjust beam parameters dynamically while using a simplified, less complex configuration mechanism that handles all modes through parameter modification rather than separate configuration procedures.
