Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio access technologies and signal transmission schemes are available for data transmission, then the system has high adaptability and versatility, but the energy consumption increases due to lack of fine-grained energy optimization
Solution Approach 1:
The patent implements dynamic selection of radio access technologies and signal transmission schemes based on real-time energy intensity indications and user equipment energy priority information. The system continuously adapts the radio access technology used for data transmission according to current network conditions and user preferences, rather than using a static configuration. This dynamic approach enables the system to optimize energy consumption while maintaining adaptability to different service requirements.
Solution Approach 2:
The patent changes the parameter of energy intensity consideration in radio access technology selection. By introducing energy intensity indications for different radio access technologies and signal transmission schemes, and incorporating user equipment energy priority information, the system modifies the selection criteria to include fine-grained energy optimization. This parameter change enables the network to choose among multiple radio access technologies not only based on performance but also on energy efficiency metrics.
2Use of energy by moving object
If energy intensity indication and energy priority information are used to select radio access technologies, then energy consumption is reduced, but the device complexity increases due to additional information processing requirements
Solution Approach 1:
The patent implements a feedback mechanism where the network provides energy intensity indications to the user equipment, and the user equipment responds by selecting radio access technologies based on its energy priority information. This feedback loop allows the system to optimize energy consumption without requiring complex local processing at the user equipment side. The user equipment simply compares the received energy intensity indications with its stored energy priority information and makes selection decisions based on this comparison, reducing the processing complexity burden.
Solution Approach 2:
The patent introduces energy intensity indications as an intermediary information element that mediates between the network's radio access technology options and the user equipment's energy priority preferences. Instead of requiring the user equipment to directly evaluate and compare multiple complex radio access technology parameters, the network pre-processes this information and provides simplified energy intensity indications. This intermediary representation reduces the computational burden on the user equipment while still enabling fine-grained energy optimization.
3Loss of energy
If fine-grained energy intensity optimization is implemented, then energy efficiency improves, but the system requires additional signaling and information exchange between network and user equipment
Solution Approach 1:
The patent makes the energy intensity indication mechanism universal by integrating it into the existing radio resource management framework. The same signaling infrastructure used for traditional radio resource allocation and quality of service management is extended to carry energy intensity indications. This multi-functional use of existing signaling channels minimizes the additional overhead required for energy optimization, as the same communication infrastructure serves multiple purposes including resource allocation, quality assurance, and energy efficiency management.
Data Source
AI summary
A method for factoring energy intensity of data transmissions between a user equipment (UE) and a network, in order to take into account the energy intensity of data transmissions between the UE and the network, includes the UE receiving an energy intensity indication, the energy intensity indication being related to at least one radio access technology for communicating data. A radio access technology is selected by the UE based on energy intensity indication and energy priority information, where the energy intensity indication refers to the energy intensity of data transmissions between the UE and the network in terms of energy per data volume transmitted, energy per bandwidth used, or energy per latency realized.
