Engineering Contradiction Analysis
1Productivity
If dynamic resource allocation is implemented, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic TCI state pool indication where the gNodeB can dynamically switch between different TCI state pools (first TCI state pool and second TCI state pool) based on real-time network conditions and UE capabilities. This dynamic adaptation allows the system to optimize resource allocation while managing complexity through predefined pools rather than completely flexible configuration.
Solution Approach 2:
The patent segments TCI state pools into distinct first and second TCI state pools, each containing specific TCI states. This segmentation allows the system to manage complexity by dividing the large space of possible TCI configurations into manageable subsets, while still enabling dynamic selection between pools to optimize network efficiency.
2Adaptability or versatility
If multiple TCI state pools are supported, then adaptability to different UE capabilities is improved, but configuration complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple TCI state pools with different TCI states before actual communication begins. The gNodeB prepares these pools in advance and can selectively activate appropriate pools based on UE capabilities, avoiding the need for complex real-time configuration while maintaining high adaptability.
Solution Approach 2:
The system manages adaptability through parameter changes by switching between different TCI state pools, each defined by specific TCI state parameters. This approach allows the system to adapt to different UE capabilities by changing which pool is active, rather than reconfiguring individual parameters, thereby reducing configuration complexity.
3Productivity
If dynamic TCI state indication is implemented, then bandwidth optimization is improved, but processing time increases
Solution Approach 1:
The patent reduces processing time by performing preliminary configuration of multiple TCI state pools in advance. When bandwidth optimization is needed, the system can quickly switch between pre-configured pools rather than performing complex real-time configuration, thereby achieving fast bandwidth adaptation with minimal processing delay.

AI summary
A method for beam determination may include receiving, by a wireless device from a base station, configuration parameters indicating transmission configuration indication (TCI) state pools, wherein each TCI state pool, of the TCI state pools, comprises TCI states. The method may also include transmitting an indication of a TCI state pool from the TCI state pools.
