Engineering Contradiction Analysis
1Reliability
If multiple panels and antennas are used in power control and beam management systems, then data transmission quality and network efficiency are improved, but device complexity and power management difficulty increase
Solution Approach 1:
The patent segments the power control process by introducing separate power control parameter sets for different panels and antennas. Each panel/antenna group can have independently configured power parameters, allowing granular control over multiple transmission elements without managing them as a monolithic complex system. This segmentation enables the system to handle multiple antennas/panels through modular, independent parameter management.
Solution Approach 2:
The patent implements dynamic power control where power parameters are continuously adjusted based on transmission requirements and radio conditions. The system dynamically selects appropriate power control parameter sets and applies them to different panels and antennas in real-time, enabling adaptive optimization of data transmission quality while managing complexity through automated dynamic adjustment rather than static complex configurations.
2Productivity
If advanced power control operations with multiple panels are implemented, then network efficiency and coverage are improved, but power usage and energy consumption increase
Solution Approach 1:
The patent employs parameter changes by introducing multiple power control parameter sets with different configurations. The system selectively applies appropriate parameter sets based on transmission requirements, radio conditions, and panel/antenna states. This allows the system to optimize network efficiency and coverage by adjusting power parameters dynamically rather than maintaining high power consumption continuously, thereby improving productivity while managing energy usage through intelligent parameter selection and adjustment.

AI summary
A wireless device receives a medium access control control element (MAC CE) indicating a power control parameter set of power control parameter sets for uplink transmissions by the wireless device via physical uplink shared channel (PUSCH) resources and a pathloss reference signal (RS), of pathloss RSs for the uplink transmissions via the PUSCH resources, associated with the power control parameter set. The wireless device receives downlink control information indicating a PUSCH resource and the power control parameter set. The wireless device transmits, via the PUSCH resource, an uplink signal with a transmission power that is based on the pathloss RS associated with the power control parameter set.
