Sidelink Resource Allocation Parameter Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication technologies face challenges in efficiently allocating resources between shared and discovery resource pools, leading to ambiguity in determining the correct resource pool for transmission or discovery operations.
Innovation Solution
A method and apparatus for a user equipment (UE) to receive configurations for multiple resource pools, determine the allocated resources based on a resource allocation parameter, and perform either transmission or discovery operations accordingly, ensuring clear allocation between shared and discovery resource pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resource pools (shared and discovery) are configured for sidelink communication, then resource allocation flexibility and communication efficiency are improved, but ambiguity arises in determining the correct resource pool for transmission or discovery operations
Solution Approach 1:
The patent introduces a resource allocation parameter as an intermediary element that mediates between the resource pool configuration and the actual resource selection. This parameter, received in downlink control information, clearly indicates which resource pool (shared or discovery) should be used, eliminating ambiguity while maintaining the flexibility of having multiple resource pools configured
Solution Approach 2:
The patent applies different characteristics to different resource pools by associating them with different resource allocation parameters. The shared resource pool is associated with one parameter while the discovery resource pool is associated with another, allowing each pool to maintain its specific properties while being clearly distinguishable through the parameter mapping
2Productivity
If resource allocation parameters are mapped to multiple resource pools, then resource utilization efficiency is improved, but complexity increases in determining the correct mapping
Solution Approach 1:
The patent segments the resource allocation process by introducing distinct resource allocation parameters for different resource pools. Instead of using a single ambiguous parameter, the system divides the parameter space into separate segments (e.g., first resource allocation parameter for shared pool, second for discovery pool), making the determination process simpler while maintaining efficient resource utilization
Solution Approach 2:
The patent performs preliminary action by pre-configuring the mapping between resource allocation parameters and resource pools through downlink control information. This preliminary mapping is established before the actual resource allocation, so that when resources need to be allocated, the correct pool is already identified through the pre-established parameter-to-pool association, reducing determination complexity

AI summary
There is provided an apparatus, comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform: receiving a configuration indicative of at least a first resource pool and a second resource pool, wherein the first resource pool is for a different purpose than the second resource pool; receiving downlink control information comprising a resource allocation parameter defining allocated resources in the first resource pool or allocated resources in the second resource pool; and determining, based on the resource allocation parameter, allocated resources in the first resource pool or in the second resource pool.
