Configured Grant Resource Status Notification for Uplink Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technology, terminals sharing resources often experience collisions, which affect latency and reliability, while exclusive resource occupation leads to low resource utilization.
Innovation Solution
A resource transmission method that involves obtaining notification signaling from a network device regarding the status of configured grant resources, selecting an idle resource for transmission, or sending a scheduling request when all resources are occupied, to ensure real-time transmission and retransmission scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If terminals share resources, then resource utilization rate is improved, but collision occurs among terminals affecting latency and reliability
Solution Approach 1:
The network device monitors the occupancy status of configured grant resources and sends notification signaling to terminals. This feedback mechanism allows terminals to adjust their resource selection based on real-time resource status, avoiding collisions while maintaining high resource utilization. The notification signaling provides information about which resources are occupied, enabling terminals to make informed decisions about resource selection.
2Reliability
If each terminal occupies a resource exclusively, then no collision occurs among terminals, but resource utilization rate is lowered
Solution Approach 1:
The patent implements dynamic resource allocation where terminals can switch between exclusive occupation and shared usage based on real-time conditions. The network device dynamically adjusts resource allocation by sending notification signaling that indicates resource occupancy status. This allows the system to transition from static exclusive allocation to dynamic shared allocation, improving resource utilization while maintaining reliability through collision avoidance mechanisms.
3Quantity of substance
If terminals share configured grant resources, then resource utilization is improved, but collision detection and resolution complexity increases
Solution Approach 1:
The network device acts as an intermediary that manages resource allocation and collision detection. Instead of terminals independently detecting and resolving collisions (which would be complex), the network device monitors resource status and provides notification signaling to terminals. This intermediary approach simplifies terminal complexity while enabling efficient resource sharing and collision avoidance.

AI summary
The present disclosure provides a resource transmission method, a terminal and a network device. When the method is applied to a terminal, it includes: obtaining a notification signalling sent by a network device according to the status of a configured grant resource, the notification signalling comprises configured grant resource status information, and the configured grant resource status information comprises at least one of an idle state and an occupied state; selecting, according to the configured grant resource status information, a configured grant resource in an idle state to transmit a physical uplink shared channel PUSCH, or sending a scheduling request SR when the configured grant resources are all in the occupied state.
