Uplink Grant Feedback for Reusing Unused Radio Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed size of uplink resources configured by the access network device for terminal devices in the uplink configured grant manner fails to flexibly match the dynamically variable size of service data, leading to resource waste and network capacity issues.
Innovation Solution
The terminal device sends indication information to the access network device about unused resources, allowing the network to reschedule or reuse these resources, thereby aligning both parties' resource awareness and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the access network device configures a fixed-size uplink resource for the terminal device, then the resource allocation is simple and stable, but the resource cannot flexibly match the dynamically variable service data size, causing resource waste
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the terminal device to report unused resources and the access network device to reschedule them. The resource configuration transitions from a static fixed size to a dynamic adjustment mechanism where resource size changes based on actual service data needs, resolving the contradiction between adaptability and complexity
Solution Approach 2:
The patent introduces a feedback loop where the terminal device monitors and reports unused uplink resources to the access network device. This feedback mechanism enables the network to adjust resource allocation dynamically, achieving flexibility while maintaining manageable complexity through structured information exchange
2Reliability
If the access network device configures a large quantity of uplink resources for the terminal device, then the terminal device can handle peak data traffic, but resource waste occurs when the actual data size is small, affecting network capacity
Solution Approach 1:
The patent changes the parameter of resource size from a fixed large allocation to a dynamically adjusted size based on actual service data. By monitoring unused resources and adjusting the allocation size accordingly, the system maintains reliability for peak traffic while reducing resource waste during low-traffic periods
Solution Approach 2:
The patent initially configures excessive resources to ensure peak traffic handling capability, then applies partial action by reducing the resource allocation to match actual needs. The terminal device reports only the unused portion, and the network adjusts accordingly, achieving both reliability and efficiency

AI summary
A communication method and apparatus are provided, which relate to the field of communication technologies. The method includes: sending first indication information to an access network device. The first indication information indicates a first resource not used by a terminal device, the first resource is a part or all of a second resource, and the second resource is a resource configured by the access network device for the terminal device.
