Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate power control parameters are configured for each uplink channel, then channel-specific power control can be achieved, but configuration overhead increases and redundancy occurs
Solution Approach 1:
The power control parameters are segmented into two categories: common parameters applicable to all uplink channels and differential parameters specific to each channel. This segmentation allows the system to maintain channel-specific optimization while reducing overall configuration overhead by sharing common parameters across channels.
Solution Approach 2:
Common power control parameters are merged across multiple uplink channels to eliminate redundancy. By identifying and combining parameters that are identical or similar across channels (such as maximum transmit power, path loss compensation factors), the system reduces configuration overhead while maintaining effective per-channel control through differential adjustments.
2Reliability
If redundant power control parameters are configured for each uplink channel, then comprehensive power control coverage is achieved, but configuration complexity and overhead increase
Solution Approach 1:
Redundant parameters are extracted and removed from individual channel configurations. By identifying parameters that are duplicated across channels and extracting them to a common configuration set, the system maintains comprehensive power control coverage while significantly reducing configuration complexity and overhead.
Solution Approach 2:
Common power control parameters are designed to serve multiple uplink channels simultaneously, achieving universality. These multi-functional parameters provide baseline power control for all channels, eliminating the need for separate redundant configurations while ensuring comprehensive coverage across different channel types.
3Manufacturing precision
If numerous power control parameters with multiple possible values are provided for each channel, then fine-grained power control is achieved, but overhead increases without clear guidance on usage
Solution Approach 1:
Different levels of parameter specificity are applied to different channels based on their actual needs. While common parameters provide baseline precision for all channels, differential parameters provide additional local optimization only where required, achieving fine-grained control where necessary without uniformly increasing overhead across all channels.
Solution Approach 2:
The parameter configuration system is made dynamic by allowing selective application of differential parameters based on channel conditions and requirements. This dynamic approach enables the system to maintain high precision when needed while reducing overhead in scenarios where common parameters suffice, providing flexibility in parameter usage.

AI summary
One or more first transmit power control parameters that are common to transmit power control for multiple different physical uplink channels are transmitted by a network device and received by a user equipment (UE) in a wireless communication network. The UE transmits, and the network device receives, one of the multiple different physical uplink channels. That uplink channel is transmitted at a transmit power that is based on the first transmit power control parameter(s) and one or more second transmit power control parameters that are specific to the transmit power control for the uplink channel.
