1Productivity
If multiple cells and bandwidth parts are configured for a terminal, then the system can support explosive data traffic and increased number of connected devices, but the complexity of configuring and managing beam linkage states and spatial parameters increases significantly
Solution Approach 1:
The patent applies universality by introducing a unified beam linkage state (BLS) configuration mechanism that works across multiple cells and bandwidth parts. The BLS concept provides a universal framework for managing spatial parameters regardless of which specific cell or bandwidth part is being used, allowing the same configuration approach to be applied systematically across diverse network scenarios.
Solution Approach 2:
The patent segments the complex spatial parameter management into distinct beam linkage state configurations for different resources. Each BLS is separately configured and identified, allowing independent management of spatial parameters for different cells and bandwidth parts, which simplifies the overall complexity by breaking down the monolithic configuration problem into manageable segments.
2Adaptability or versatility
If beam linkage states are configured for multiple resources with mapping relations between reference and target transmissions, then spatial parameter determination becomes more flexible, but the signaling overhead increases
Solution Approach 1:
The patent uses copying by configuring beam linkage states that reference previously established spatial parameters. Instead of transmitting complete spatial parameter sets for every resource, the system creates references (copies) to existing configurations, significantly reducing signaling overhead while maintaining the ability to determine appropriate spatial parameters for target transmissions.
Solution Approach 2:
The patent applies preliminary action by pre-configuring beam linkage states and their associated mapping relations between reference and target transmissions. This advance configuration allows the system to quickly determine spatial parameters during actual transmission without requiring real-time complex calculations or extensive signaling, thus reducing overhead while maintaining flexibility.
3Measurement precision
If reference spatial parameter indication information is transmitted for reference transmission, then accurate spatial parameter determination is achieved, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies local quality by providing reference spatial parameter indication information selectively for specific reference transmissions that require it, rather than uniformly for all transmissions. This targeted approach ensures accurate spatial parameter determination where needed while minimizing unnecessary signaling overhead for cases where default or previously determined parameters suffice.
