D2D Resource Coordination via Base Station Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Device-to-Device (D2D) communication, the existing resource acquisition manner leads to interference and incorrect data reception due to uncoordinated resource selection by multiple D2D UEs, resulting in poor data transmission and reception success rates.
Innovation Solution
A first UE transmits configuration information of a transmission and/or reception resource or resource pool to a second UE, which is used for indicating resource information in their information interaction, thereby improving the success rate of data transmission and/or reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple D2D UEs select resources independently without coordination, then resource acquisition is simple and fast, but interference increases and data transmission success rate deteriorates
Solution Approach 1:
The patent introduces a base station as an intermediary to coordinate resource allocation among D2D UEs. The base station receives resource requests from UEs, determines appropriate transmission and reception resources, and allocates them to avoid interference. This mediator approach maintains relatively simple UE operations while significantly improving transmission reliability through centralized coordination.
2Reliability
If a base station schedules and allocates dedicated resources to each D2D UE, then data transmission success rate improves, but system complexity and resource allocation overhead increase
Solution Approach 1:
The patent segments the resource allocation process into distinct phases: D2D resource pool configuration, resource request submission, resource determination, and resource allocation. By dividing the complex allocation process into manageable segments with clear interfaces, the system achieves reliable coordinated resource allocation while keeping individual UE operations simple and well-defined.
3Productivity
If D2D UEs use the same resource pool for both transmission and reception, then resource utilization efficiency improves, but interference between simultaneous transmission and reception occurs
Solution Approach 1:
The patent resolves the self-interference problem by separating transmission and reception resources in the time dimension. The base station allocates different time resources for transmission versus reception, allowing UEs to use the same frequency resource pool without simultaneous transmission-reception conflicts. This dimensional separation maintains high resource utilization while eliminating self-interference.

AI summary
A resource processing method and device are provided. In the method, a first UE transmits configuration information of a transmission and/or reception resource or resource pool to a second UE, and the resource or resource pool is used for indicating resource information used in information interaction between the second UE and the first UE. The solution solves a problem existing in data transmission and/or reception caused by a resource acquisition manner in a related technology, and improves the success rate of data transmission and/or reception.
