Dynamic SPS Resource Configuration for Varying Packet Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-persistent scheduling (SPS) configurations in communications systems, such as LTE, are inflexible and cannot effectively manage changes in data packet size or interval, leading to suboptimal data transmission quality and resource inefficiency.
Innovation Solution
Implementing a dynamic scheduling resource configuration method that adjusts SPS resources based on specific data packet features and historical data patterns, allowing for real-time reconfiguration of scheduling parameters like packet size, interval, and resource allocation to match changing service requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If semi-persistent scheduling (SPS) is used to save PDCCH resources, then resource efficiency is improved, but the system cannot adapt to changes in data packet size or interval
Solution Approach 1:
The patent implements dynamic SPS configuration where the base station monitors data packet characteristics (size, interval) and adjusts SPS parameters in real-time. This transforms the static SPS mechanism into a dynamic one that can adapt to changing traffic patterns while maintaining resource efficiency.
Solution Approach 2:
The system introduces feedback mechanisms where the base station monitors actual data packet characteristics and uses this information to dynamically adjust SPS configuration. The monitoring module tracks packet size and interval changes, and the configuration module responds by updating SPS parameters accordingly.
2Adaptability or versatility
If dynamic configuration is implemented to adapt to packet changes, then adaptability is improved, but system complexity increases
Solution Approach 1:
The base station autonomously monitors data packet characteristics and performs self-configuration of SPS parameters without requiring complex external control systems. The monitoring and configuration functions are integrated within the base station, enabling it to adapt automatically to traffic changes.
Solution Approach 2:
The patent combines the monitoring function and configuration function into an integrated system at the base station. By merging these functions and sharing data between them, the system reduces overall complexity compared to having separate independent systems.
3Loss of energy
If SPS resource is allocated for small data packets, then resource efficiency is improved, but transmission quality deteriorates when packet size increases
Solution Approach 1:
The SPS resource allocation is made dynamic based on monitored packet characteristics. When small packets are detected, efficient SPS allocation is maintained. When packet size increases beyond thresholds, the system dynamically adjusts resource allocation to ensure transmission quality.
Solution Approach 2:
The system changes SPS configuration parameters (such as resource allocation size, periodicity) based on monitored data packet characteristics. When packet size or interval exceeds predefined thresholds, parameters are adjusted to maintain transmission quality while preserving resource efficiency for appropriate traffic types.

AI summary
This application discloses a scheduling resource configuration method and apparatus, user equipment, and a base station, so as to obtain, from a location such as a core network or a user terminal, related data, including a data packet size, a packet interval, historical data, or the like, of a service that is currently executed by the user terminal, and further generate and configure scheduling configuration information such as SPS scheduling configuration information based on the data. The base station and the user terminal both run, based on the generated scheduling configuration information, the service that is currently executed by the user equipment. In addition, the base station or the user equipment may further select scheduling configuration information from a plurality of pieces of scheduling configuration information depending on a requirement. This implements dynamic configuration of a scheduling resource such as an SPS resource, effectively saves resources, such as PDCCH resources, used for a scheduling indication in a system, and can also ensure, to fullest extent, data transmission quality of some services whose data packet sizes, periods, or the like change.
