Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal measures and reports measurement results of multiple BWPs, then the BWP switching speed is improved, but the measurement and reporting complexity increases
Solution Approach 1:
The patent extracts only the necessary measurement results for reporting. Instead of reporting all N BWP measurement results, the terminal selectively reports only M BWP results (where M < N) that meet specific reporting conditions, thereby reducing reporting complexity while maintaining fast switching capability.
Solution Approach 2:
The patent implements preliminary action by pre-configuring reporting conditions and criteria before actual BWP measurements. The terminal evaluates measurement results against pre-defined conditions to determine which BWPs should be reported, streamlining the measurement and reporting process.
2Measurement precision
If the terminal reports measurement results of all N BWPs, then the measurement precision is improved, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the essential measurement information needed for BWP switching decisions. By reporting only M selected BWP results instead of all N results, the patent reduces signaling overhead while preserving the precision needed for effective BWP selection.
Solution Approach 2:
The patent applies partial action by reporting a subset of BWP measurement results rather than all results. The terminal reports only those M results that are sufficient for the network to make informed BWP switching decisions, avoiding the excessive signaling overhead of reporting all N results.
3Adaptability or versatility
If the terminal activates multiple inactive BWPs for measurement, then the adaptability is improved, but the processing load increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring the set of N BWPs that may be measured before the terminal enters high-speed movement. This allows the network to prepare appropriate BWP candidates in advance, reducing the real-time processing load when switching is needed.
Solution Approach 2:
The patent applies dynamics by allowing the BWP measurement and reporting process to adapt to terminal movement states. The network configures BWP measurement resources dynamically based on whether the terminal is in high-speed movement, optimizing the balance between adaptability and processing load.

AI summary
A method for reporting bandwidth part (BWP) measurement is performed by a terminal, and includes: measuring signal qualities of reference signals of N BWPs within a BWP set; and in response to a reporting condition being satisfied, reporting measurement results of M BWPs to a network device, wherein the M BWPs are selected from the N BWPs based on the signal qualities; wherein N is an integer greater than 1, and M is an integer not greater than N.
