Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional data transmission procedures are used for MT-EDT, then complete data transmission can be achieved, but signaling overhead increases and transmission efficiency decreases
Solution Approach 1:
The patent combines downlink data transmission with uplink data transmission by configuring the terminal to send uplink data in response to downlink data within the same early data transmission procedure. This merging of transmission directions reduces the need for separate signaling procedures, thereby reducing signaling overhead while maintaining transmission efficiency
Solution Approach 2:
The patent enables the early data transmission resource to serve multiple purposes: receiving downlink data, sending uplink data, and triggering RRC connection establishment or resumption. This multi-functionality allows a single transmission procedure to handle multiple communication needs, reducing overall signaling overhead
2Loss of information
If simplified transmission procedures are used, then signaling overhead is reduced, but transmission reliability and security may be compromised
Solution Approach 1:
The patent performs preliminary configuration of transmission resources and security parameters before actual data transmission. The network configures the terminal with uplink transmission resources, power control parameters, and security settings in advance, ensuring that when data transmission occurs, all necessary security and reliability measures are already in place
Solution Approach 2:
The patent implements feedback mechanisms where the terminal confirms receipt of downlink data and successfully transmits uplink data. The network receives acknowledgment from the terminal, providing feedback that ensures reliable delivery. This feedback loop maintains transmission reliability while using efficient signaling
3Reliability
If RRC connection is established for every data transmission, then transmission reliability is ensured, but signaling overhead and latency increase
Solution Approach 1:
The patent performs preliminary configuration of transmission resources and security parameters before actual data transmission. The network configures the terminal with uplink transmission resources, power control parameters, and security settings in advance, ensuring that when data transmission occurs, all necessary security and reliability measures are already in place
Solution Approach 2:
The patent enables the terminal to remain in a connected state or quickly resume connection by utilizing configured uplink resources to send data immediately upon receiving downlink data. This continuous action approach avoids repeated connection establishment and maintenance cycles, reducing time loss while ensuring reliability through maintained connection state
