Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible/full duplex standard supports asymmetric spectrums with varying frequency domain locations and sizes of uplink and downlink resources at different time units, then spectrum utilization and communication flexibility are improved, but terminal's ability to determine specific start RB for data transmission deteriorates
Solution Approach 1:
The network side device performs preliminary action by determining the frequency domain resource assignment in advance and notifying the terminal of the target start RB through indication information. This allows the terminal to know the exact start RB for data transmission before actually transmitting, resolving the uncertainty caused by asymmetric spectrums in flexible/full duplex mode.
Solution Approach 2:
The patent introduces an intermediary mechanism where the network side device acts as a mediator between the asymmetric spectrum configuration and the terminal's resource determination. The network side device receives the frequency domain resource assignment, determines the target start RB, and conveys this information to the terminal through indication information, thereby bridging the gap caused by resource asymmetry.
2Productivity
If asymmetric spectrums are used in flexible/full duplex standard, then spectrum efficiency is improved, but complexity of determining transmission resources increases
Solution Approach 1:
The patent extracts the complex determination logic from the terminal and relocates it to the network side device. The network side device performs the complex calculation of determining the target start RB based on the frequency domain resource assignment, while the terminal only needs to receive the indication information and execute transmission. This extraction reduces terminal complexity while maintaining spectrum efficiency.
3Adaptability or versatility
If frequency domain locations and sizes of uplink and downlink resources vary at different time units, then communication adaptability is improved, but reliability of resource determination deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the network side device monitors the asymmetric resource configuration and provides feedback to the terminal through indication information containing the target start RB. This feedback ensures that the terminal's resource determination is reliable even when frequency domain locations and sizes vary across time units, as the network side device continuously adjusts and communicates the correct resources.
