Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal performs uplink sending on a maximum of two transmit channels simultaneously, then device complexity is reduced and ease of operation is improved, but adaptability deteriorates as the terminal cannot support more than two uplink bands
Solution Approach 1:
The patent segments the transmit channel resources by introducing the concept of transmit channel groups, where each group can be independently configured and managed. This allows the terminal to handle multiple transmit channels across different bands by dividing them into manageable groups, thereby improving adaptability while controlling complexity through structured organization of channel resources.
2Adaptability or versatility
If a terminal supports switching between only two uplink bands, then ease of operation is maintained, but adaptability deteriorates as the terminal cannot switch between more than two bands
Solution Approach 1:
The patent implements dynamic band switching capability through configurable transmit channel groups that can be flexibly adjusted based on network requirements and terminal capabilities. The switching mechanism is enhanced to support arbitrary numbers of bands by maintaining dynamic state information about available transmit channels and their associations with different bands, allowing the terminal to adaptively switch between any supported bands rather than being limited to fixed pairs.
3Adaptability or versatility
If the terminal determines target parameters for transmission or switching based on target information from multiple physical units, then adaptability improves for multi-band transmission, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary layer in the parameter determination process by using target information structures that aggregate and organize data from multiple physical units. This intermediary representation simplifies the complexity by providing a unified view of multi-band transmission parameters, allowing the terminal to determine target parameters through systematic processing of organized information rather than directly managing complex multi-unit configurations.

AI summary
This application provides a parameter determining method, a terminal, and a network side device. The parameter determining method includes: when a terminal performs transmission on at least one of N physical units, determining, by the terminal based on target information, a target parameter used for transmission or switching. The transmission is transmission based on at least one of M transmit channels, or the transmission is transmission based on at least one of M transmit channels on a physical unit after transmit channel switching. Nis an integer greater than 2, and M is a positive integer less than or equal to N.
