Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional grid representation is used for resource allocation, then signaling information is complete and accurate, but signaling overhead increases and transmission success probability decreases
Solution Approach 1:
The patent segments the traditional resource allocation grid into multiple sub-grids or resource pools, allowing independent allocation and signaling for each segment. This reduces the overall signaling overhead while maintaining comprehensive resource coverage and transmission reliability through distributed resource selection.
Solution Approach 2:
The patent introduces dynamic resource allocation mechanisms where the grid structure and resource assignment can adapt based on channel conditions, interference levels, and traffic demands. This dynamic approach improves transmission success probability by selecting optimal resources in real-time while reducing signaling overhead through compact representation of changes.
2Loss of information
If frequency resources are grouped for signaling optimization, then signaling overhead is reduced, but frequency diversity and interference robustness are compromised
Solution Approach 1:
The patent applies local quality by creating different resource grouping strategies for different frequency bands or resource pools, where each group is optimized for specific characteristics such as interference patterns or channel conditions. This allows signaling overhead reduction through grouping while maintaining frequency diversity and interference robustness through localized optimization.
Solution Approach 2:
The patent employs composite resource allocation strategies that combine multiple resource groups with different diversity properties. By allocating transmissions across composite sets of grouped resources, the system achieves both signaling efficiency and robustness against interference through diversified resource selection.
3Productivity
If resource allocation is optimized for one system, then that system's performance improves, but joint optimization between systems becomes necessary increasing complexity
Solution Approach 1:
The patent designs a universal resource allocation framework that can be applied independently by different systems or networks. The standardized grid representation and allocation mechanisms allow each system to optimize its own resource usage without requiring complex joint optimization, achieving high productivity while maintaining manageable system complexity.

AI summary
For determining time and frequency resources to be used for performing transmissions in a wireless communications network, the transmissions being performed via time and frequency resources of the wireless communications network according to an initial grid representation, a first device performs: obtaining groups of time and frequency resources of the wireless communications network so as to form a redrawn grid; allocating time and frequency resources according to the redrawn grid and to a frequency hopping criteria; and providing signalling information representative of the time and frequency resources that have been allocated according to the redrawn grid. In order to determine which time and frequency resources of the initial grid to be used for performing said transmissions, a second device performs: obtaining the signalling information so as to determine the time and frequency resources that have been allocated according to the redrawn grid; and applying a predetermined pattern mask onto the determined time and frequency resources that have been allocated according to the redrawn grid.
