Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-contiguous sub-carriers are allocated to mobile stations, then resource allocation flexibility and scheduling gain are improved, but signaling complexity and resource management overhead increase
Solution Approach 1:
The patent segments the allocated sub-carriers into contiguous resource blocks grouped into clusters. Each cluster is identified by a starting sub-carrier index and a size, allowing non-contiguous allocations to be represented as multiple standardized segments. This segmentation enables flexible resource allocation while simplifying signaling through structured cluster representations.
Solution Approach 2:
The patent changes the parameter representation from individual sub-carrier indices to cluster-level parameters (starting index and size). This parameter transformation reduces the number of bits needed for signaling and simplifies the mobile station's processing, as it only needs to interpret cluster parameters rather than individual sub-carrier assignments.
2Measurement precision
If detailed sub-carrier allocation information is provided, then resource identification accuracy is improved, but signaling overhead and processing time increase
Solution Approach 1:
The patent merges multiple individual sub-carrier assignments into unified cluster representations. Instead of signaling each sub-carrier separately, the base station provides cluster parameters that encompass multiple contiguous sub-carriers. This merging maintains accurate resource identification while significantly reducing signaling overhead and processing time.
Solution Approach 2:
The patent establishes a predefined structure for cluster representation before actual resource allocation occurs. The mobile station is configured to expect cluster parameters with specific fields (starting index, size), allowing it to rapidly interpret allocation information without complex parsing. This preliminary structuring enables fast processing while maintaining accuracy.

AI summary
The present invention concerns a method for determining information which enable a mobile station to identify which resources of a wireless telecommunication network are allocated to the mobile station. The allocated resources are divided into plural non contiguous clusters of resources. The method comprises the steps of: - allocating resources to the mobile station, - determining, from the allocated resources, plural ordered parameters, each parameter being equal to a number of contiguous resources allocated or not to the mobile station, - calculating, for the first parameter, the number of possibilities of having a subset of resources comprising an amount of resources that is lower than the first parameter, - calculating, for each following parameter, the number of possibilities of having subsets of resources comprising amounts of resources that are respectively equal to the respective parameters having a lower rank than said following parameter and having a subset of at least one resource comprising an amount of resources that is lower than said following parameter, - determining information by summing all the calculated numbers.
