Semi-Persistent Scheduling Configuration Management in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a challenge in managing the fluctuation of Semi-Persistent Scheduling (SPS) transmission situations, particularly in scenarios where multiple SPS configurations are activated, leading to inefficiencies in resource allocation and usage.
Innovation Solution
A method is proposed where a User Equipment (UE) receives Semi-Persistent Scheduling configuration information from a base station, activates or deactivates SPS resources based on specific triggering conditions, and reports transmission state information to the base station, allowing for adaptive SPS resource management and efficient allocation among UE devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SPS configurations are activated for a UE, then the UE can support diverse service requirements and improve adaptability, but the complexity of managing and allocating SPS resources increases significantly
Solution Approach 1:
The patent segments SPS configurations into multiple distinct configuration sets (e.g., first SPS configuration, second SPS configuration) that can be independently activated and managed. Each configuration can be associated with different services or traffic types, allowing the network to selectively activate only the necessary configurations for each UE, thereby maintaining adaptability while reducing management complexity through organized segmentation.
Solution Approach 2:
The patent implements dynamic SPS configuration management where the network can activate, deactivate, or modify SPS configurations based on real-time service requirements and UE conditions. The system dynamically adjusts which SPS configurations are active for each UE, enabling flexible adaptation to changing traffic patterns while maintaining manageable complexity through on-demand configuration activation rather than permanent activation of all configurations.
2Productivity
If SPS resources are allocated based on fluctuating transmission situations, then resource allocation efficiency improves, but the stability and predictability of resource allocation deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple SPS configuration sets with predetermined resource allocation parameters before actual transmission occurs. The network prepares various SPS configurations in advance, each optimized for different service types or traffic conditions, and stores them for later activation. This allows the system to quickly switch between pre-prepared configurations based on changing conditions, achieving efficient adaptive allocation while maintaining stability through the use of pre-validated configuration parameters.

AI summary
A method for allowing a wireless resource to be allocated in a wireless communication system, and a device therefor are disclosed. Particularly, a method by which a terminal allows a wireless resource to be allocated in a wireless communication system can comprise the steps of: receiving, from a base station, one or more pieces of semi-persistent scheduling (SPS) configuration information comprising semi-persistent resource allocation information; receiving, from the base station, an SPS activation on specific SPS configuration information among the one or more pieces of SPS configuration information; allowing a specific SPS resource to be allocated on the basis of the specific SPS configuration information; and reporting, to the base station, information indicating a transmission state of the one or more pieces of SPS configuration information when a transmission of an SPS message using the specific SPS resource is stopped.
