Engineering Contradiction Analysis
1Productivity
If a single PUSCH configuration is used for uplink transmissions, then device complexity is reduced, but communication efficiency and throughput are degraded in multi-panel scenarios
Solution Approach 1:
The patent segments the uplink configuration into multiple PUSCH configuration sets, where each set is associated with a specific antenna panel. This allows the UE to use different configurations for different panels, optimizing performance for each panel's specific characteristics and transmission scenario.
Solution Approach 2:
The patent introduces dynamic configuration selection mechanisms where the UE can dynamically choose which PUSCH configuration set to use based on the active antenna panel. This dynamic adaptation enables the system to optimize communication efficiency according to real-time transmission conditions while managing complexity through structured configuration management.
2Productivity
If multiple PUSCH configurations are configured for different antenna panels, then throughput is improved, but processing resource overhead increases
Solution Approach 1:
The patent applies local quality by tailoring specific PUSCH configuration parameters (such as transform precoder settings, MCS tables, and power control parameters) to match the characteristics of each antenna panel. This localized optimization improves throughput for each panel while avoiding the need to maintain multiple complete configuration sets, thereby reducing processing overhead.
Solution Approach 2:
The patent creates a universal configuration framework where a single PUSCH configuration set can serve multiple antenna panels through selective application. The UE can apply the same or different configurations from the configured sets to different panels based on transmission requirements, achieving multi-functionality that improves throughput while managing processing resources efficiently.
3Productivity
If multiple PUSCH configurations are used for multi-panel transmissions, then resource usage optimization is achieved, but configuration management complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple PUSCH configuration sets before multi-panel transmissions begin. The network can configure these sets in advance based on expected transmission scenarios, and the UE prepares the configuration structures beforehand. This preliminary setup enables efficient resource usage during actual transmissions while reducing the complexity of real-time configuration management.

AI summary
A user equipment may receive a first physical uplink shared channel (PUSCH) configuration and a second PUSCH configuration. The user equipment may transmit a first uplink communication and a second uplink communication using different antenna panels, based at least in part on the first PUSCH configuration and the second PUSCH configuration.
