Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to dynamically allocate radio resources in D2D communication scenarios, leading to situations where users may not find available resources despite existing unused resources in the network, resulting in inefficient resource utilization.
Innovation Solution
A resource controller that measures actual resource requirements from user equipment and dynamically adjusts resource allocation between cellular and D2D communication pools based on usage metrics, ensuring optimal distribution and utilization of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user equipment independently select resources from the second pool for D2D services, then device autonomy and flexibility is improved, but resource controller overview of overall resource usage deteriorates
Solution Approach 1:
The resource controller requests measurements from user equipment regarding the occupation of device-to-device resources. The user equipment performs these measurements and signals the results back to the resource controller. This feedback mechanism enables the resource controller to maintain an overview of resource usage while allowing user equipment to independently select resources from the second pool for D2D services.
2Device complexity
If resources are statically allocated for D2D communication, then resource allocation simplicity is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The system dynamically adapts the first pool of resources for cellular communication and the second pool of resources for device-to-device communication based on measured capacity utilization. The resource controller requests measurements from user equipment about D2D resource occupation, receives these measurements, and accordingly adapts the resource pools to optimize utilization efficiency while maintaining manageable complexity.
3Speed
If D2D resources are allocated without network coordination, then communication speed is improved, but resource allocation accuracy deteriorates
Solution Approach 1:
The resource controller requests measurements from user equipment regarding the occupation of device-to-device resources. The user equipment performs these measurements and signals the results back to the resource controller, which uses this feedback information to accurately adapt resource allocation between cellular and D2D communication pools.
Solution Approach 2:
The patent replaces manual or mechanical resource allocation methods with automated measurement and adaptation mechanisms. The resource controller systematically requests and processes measurement data from user equipment to dynamically adjust resource pools, substituting precise automated control for less accurate traditional allocation methods.

AI summary
The present invention provides a resource controller for resource management in a telecommunication network, the telecommunication network providing a first set of resources for cellular communication and a second set of resources for direct device-to-device, D2D, communication between UEs, the resource controller comprising a measurement request unit being arranged to request a measurement be performed by at least one user equipment, the measurement indicating a capacity utilization of the second set of resources; and a resource pool adaption unit being arranged to adapt the first set of resources and the second set of resources as a function of the performed measurement. In particular, where no resources are available for D2D communication, a UE may request a bearer setup and in response suitable resources for D2D communication are provided.
