Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If resource allocation information is provided based on a first BWP with a smaller number of RBs, then the signaling overhead is reduced and resource allocation is simplified, but the resource allocation cannot cover the entire second BWP with a larger number of RBs
Solution Approach 1:
The patent applies dynamic parameter mapping where the resource allocation parameters (starting RB index and number of RBs) are dynamically adjusted based on the target BWP size. When allocating resources in a second BWP with more RBs than the first BWP, the parameters are scaled and wrapped around using modulo operations to cover the extended range while maintaining the original RIV encoding structure.
Solution Approach 2:
The patent changes the interpretation parameters of resource allocation by applying mathematical transformations (multiplication by BWP size ratio and modulo operation) to map parameters from the first BWP scale to the second BWP scale. This allows the same RIV-based signaling format to adapt to different BWP sizes without increasing overhead.
2Quantity of substance
If the number of RBs in the second BWP is increased to provide more resources, then the resource pool is expanded, but the existing RIV-based resource allocation method cannot properly address all RBs in the second BWP
Solution Approach 1:
The patent introduces a dimensional transformation by mapping resource allocation from the original BWP dimension to an extended BWP dimension. The starting RB index and number of RBs are transformed using the ratio between second BWP size and first BWP size, effectively projecting allocations from a smaller dimensional space to a larger one while preserving the RIV encoding efficiency.
Solution Approach 2:
The patent dynamically adjusts the resource allocation parameters based on the target BWP size. The starting RB index is multiplied by the BWP size ratio, and the number of RBs is adjusted accordingly with wraparound using modulo operation, allowing the system to adaptively cover any BWP size without changing the fundamental RIV signaling mechanism.
3Adaptability or versatility
If a new resource allocation method is designed to cover the entire second BWP, then the resource allocation coverage is improved, but the signaling overhead and calculation complexity increase
Solution Approach 1:
The patent creates a universal resource allocation method that works across multiple BWP sizes. By using the RIV encoding scheme with dynamic parameter mapping, the same signaling format and decoding logic can handle resource allocation in BWPs of different sizes, making the system multi-functional without requiring separate allocation mechanisms for each BWP size.
Solution Approach 2:
The patent changes the interpretation parameters rather than the signaling structure itself. The starting RB index and number of RBs are mathematically transformed based on BWP size ratios, allowing the existing compact RIV format to represent allocations in larger BWPs without increasing the number of bits required for signaling.
