Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCI state changes are implemented in multiple receiving chains, then communication reliability is improved, but communication smoothness deteriorates due to timing management issues
Solution Approach 1:
The patent segments the TCI state change process by introducing separate timing parameters for different receiving chains. Each receiving chain has its own TCI state change timing managed independently, allowing the system to handle multiple chains without interference while maintaining communication reliability.
Solution Approach 2:
The patent implements dynamic timing management where the TCI state change timing is adaptively adjusted for each receiving chain based on its specific requirements. This dynamic approach allows the system to optimize performance for each chain while maintaining overall communication smoothness.
2Productivity
If multiple receiving chains are used, then communication efficiency is improved, but time management complexity increases
Solution Approach 1:
The patent divides the time management function into separate handling for each receiving chain, with dedicated timing parameters (e.g., timeOffset values) for each chain. This segmentation simplifies the overall time management by treating each chain independently rather than managing all chains as a single complex system.
Solution Approach 2:
The patent applies preliminary action by pre-configuring timing parameters and TCI state change schedules for each receiving chain before communication begins. This advance preparation reduces real-time management complexity while maintaining high communication efficiency.

AI summary
An embodiment of the present disclosure provides a method for performing communication by a UE. The method comprises the steps of: receiving a TCI state configuration at time point to from a network; configuring a first reception beam with a first antenna panel at time point t1 on the basis of the first TCI state; configuring a second reception beam with a second antenna panel at time point t2 on the basis of the second TCI state; and simultaneously performing communication with the first TRP and the second TRP by using the configured first reception beam and the configured second reception beam after tdelay from time point t0, wherein there is a time difference of toffset between time point t1 and time point t2, and tdelay includes toffset.
