Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a main radio is used to process reference signals in 5G networks, then data transfer speed and connection capability are improved, but power consumption increases
Solution Approach 1:
The patent divides the radio processing functionality into two separate radios: a main radio for high-performance data transfer and a low-power radio for reference signal processing. This segmentation allows each radio to be optimized for its specific function, with the low-power radio consuming significantly less energy when handling reference signals while the main radio focuses on high-speed data transmission.
Solution Approach 2:
The patent applies local quality by assigning different operational modes to different radio components based on the task requirements. The low-power radio is specifically configured for reference signal processing tasks where full performance is not required, while the main radio handles tasks requiring maximum performance. This localized optimization reduces overall power consumption while maintaining necessary functionality.
2Use of energy by moving object
If a low-power radio is used to process reference signals, then power consumption is reduced, but processing capability is limited
Solution Approach 1:
The patent implements dynamic radio selection where the system can switch between the main radio and low-power radio based on the specific processing requirements. The network entity and UE can dynamically determine whether to use the low-power radio for reference signals or the main radio for more demanding tasks, optimizing the balance between power consumption and processing capability in real-time.
Solution Approach 2:
The patent introduces a capability message mechanism as an intermediary that communicates the low-power radio's processing capabilities between the UE and network entity. This intermediary allows the network to appropriately configure and utilize the low-power radio's capabilities while maintaining system-wide coordination and ensuring that processing requirements are met.
3Adaptability or versatility
If dual-radio architecture is implemented, then power management flexibility is improved, but device complexity increases
Solution Approach 1:
The patent designs the low-power radio to handle multiple functions related to reference signal processing, including transmission, reception, and measurement. By making the low-power radio multi-functional within its domain, the system reduces the need for additional specialized components, thereby limiting the increase in overall device complexity while maintaining power management flexibility.

AI summary
A low-power reference signal method includes: transmitting, from a UE to a network entity, a capability message indicating a capability of the UE to process low-power reference signals using a low-power radio of the UE, wherein the low-power radio is configured to process first reference signals using less power than a main radio of the UE is configured to use to process second reference signals, the first reference signals being low-power reference signals; receiving, at the UE from the network entity, a reference signal configuration of the first reference signals; and processing, at the UE using the low-power radio, the first reference signals in accordance with the reference signal configuration.
