Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate access procedures are performed for additional data transmission, then reliability of data communication is improved, but delay and power consumption increase
Solution Approach 1:
The patent combines the indication of additional data with the pre-allocated uplink transmission by embedding a data indicator in the same physical resources. This merging eliminates the need for separate access procedures, thereby reducing delay while maintaining communication reliability through the integrated signaling approach.
Solution Approach 2:
The patent uses pre-allocated uplink resources that are configured in advance through RRC signaling. By having resources predetermined and available before transmission is needed, the system can immediately indicate additional data without requiring new resource allocation procedures, thus reducing delay while ensuring reliable communication.
2Reliability
If separate access procedures are performed for additional data transmission, then reliability of data communication is improved, but power consumption increases
Solution Approach 1:
The patent merges the data indicator signaling with the pre-allocated uplink transmission, allowing the wireless device to indicate additional data using the same resources already allocated for regular transmissions. This eliminates the need for separate access procedures that would consume additional power, thereby reducing power consumption while maintaining communication reliability.
3Loss of time
If pre-allocated uplink resources are used for additional data, then delay is reduced, but control signaling complexity increases
Solution Approach 1:
The patent extracts the data indicator as a separate element that can be embedded within the pre-allocated uplink transmission. This extraction allows the indication of additional data to be handled independently through a dedicated field or format modification, reducing delay by using existing resources while managing control signaling complexity through structured extraction of the indicator information.
4Productivity
If existing pre-allocated resources are used for additional data communication, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent makes the pre-allocated uplink resources universal by enabling them to carry both regular data transmissions and additional data indications through the embedded data indicator. This multi-functionality improves productivity by utilizing existing resources for multiple purposes while managing device complexity through a unified resource allocation approach.
