Uplink Resource Grant Release in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing uplink resources, particularly in releasing granted resources when devices do not have data to transmit, leading to suboptimal use of communication resources.
Innovation Solution
Implementing a method where wireless communication devices can transmit an uplink resource grant release message to indicate when granted uplink resources are not needed, allowing the system to repurpose these resources for other devices, and using dynamic DCI grants and configured grants to manage periodic uplink resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system maintains granted uplink resources for periodic use, then reliability of data transmission is improved, but resource utilization efficiency deteriorates when devices do not have data to transmit
Solution Approach 1:
The patent implements dynamic resource management by introducing a release message mechanism that allows UEs to dynamically indicate when they no longer need granted uplink resources. The network entity receives these release messages and reconfigures the resources accordingly, transforming the static resource allocation into a dynamic system that adapts to actual transmission needs, thereby resolving the contradiction between maintaining reliability and improving resource utilization efficiency
Solution Approach 2:
The patent establishes a feedback loop where the UE monitors its data transmission status and sends release messages to the network entity when uplink data becomes unavailable. This feedback mechanism enables the network to adjust resource allocation based on real-time conditions, ensuring resources are maintained when needed (reliability) and released when not needed (efficiency), thus resolving the technical contradiction
2Loss of energy
If the system releases uplink resources when not needed, then resource utilization efficiency is improved, but signaling overhead increases due to release messages
Solution Approach 1:
The patent applies partial action by implementing selective resource release - release messages are only transmitted when actually needed (when uplink data becomes unavailable), rather than continuously or excessively. This partial signaling approach minimizes overhead while achieving the goal of improving resource utilization efficiency, resolving the contradiction between efficiency improvement and signaling overhead
Solution Approach 2:
The UE autonomously monitors its own data transmission status and independently determines when to send release messages, without requiring continuous network intervention or complex centralized control. This self-service approach enables the system to optimize resource allocation with minimal signaling, as each UE manages its own resource release needs based on its local data availability, thus resolving the contradiction between efficiency and signaling overhead

The present disclosure provides techniques for uplink resource management. For example, a method is provided including receiving a configuration granting a plurality of periodic uplink resources for use by the first wireless communication device to transmit data on an uplink. The method further includes determining for a first uplink resource of the plurality of periodic uplink resources, that grant of the first uplink resource for use by the first wireless communication device can be released. The method further includes based on the determining for the first uplink resource, transmitting to a second wireless communication device an indication that the grant of the first uplink resource for use by the first wireless communication device can be released.
