Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing transmission systems are used without section extension for ACK/NACK requests, then the system complexity remains low, but the ability to detect transmission failures and decoding failures is insufficient
Solution Approach 1:
The patent segments the control plane message into multiple sections, each with its own acknowledgment request identifier (ackNackReqId) and length field (extLen). This segmentation allows the receiver to process and acknowledge individual sections independently, enabling failure detection at the section level while maintaining overall message integrity. The section extension divides the acknowledgment mechanism into manageable units that can be tracked separately.
Solution Approach 2:
The patent implements a feedback mechanism where the receiver sends back acknowledgment messages containing ackNackReqId fields that reference the original section descriptions. This feedback loop enables the transmitter to determine whether sections were successfully received and decoded, providing reliability through systematic confirmation while maintaining structured communication protocols.
2Reliability
If section extension with ackNackReqId and extLen fields is added to C-plane messages, then the reliability of message transmission is improved, but the message processing complexity increases
Solution Approach 1:
The patent incorporates the section extension with ackNackReqId and extLen fields directly into the original C-plane message before transmission. This preliminary action ensures that all necessary acknowledgment information is prepared in advance, allowing the receiver to immediately process and respond to each section without requiring additional setup or configuration steps, thereby improving reliability while controlling processing complexity.
Solution Approach 2:
The section extension structure serves multiple functions simultaneously: it provides length information (extLen), identification for tracking (ackNackReqId), and enables both transmission reliability and decoding verification. This multi-functionality reduces the need for separate mechanisms, balancing enhanced reliability with manageable processing complexity through a unified approach.

AI summary
Methods and apparatuses for handling an acknowledgement of C-plane message in a wireless communication system. A method of a transmitter device comprises: generating a section extension for an ACK/NACK request including an ackNackReqId field and an extLen field, wherein the ackNackReqId field indicates the ACK/NACK request ID of a section description and the extLen field indicates a size of the section extension; transmitting, to a receiver device, the C-plane message including the section extension for the ACK/NACK request; and receiving, from the receiver device, an ACK message corresponding to the C-plane message.
