SPS Transmission Indication for Multi-Broadcast Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semi-persistent scheduling (SPS) configurations in multi-broadcast scheduling (MBS) lack flexibility, as terminal devices in the same sub-group must use the same configuration, leading to inefficiencies and transmission delays, especially when service demands vary and channel conditions differ, and existing methods cannot effectively manage multiple SPS configurations to match varying terminal device needs.
Innovation Solution
A method and apparatus for determining the SPS transmission state of terminal device sub-groups through SPS transmission indication signaling, allowing for flexible configuration and efficient resource allocation by identifying and managing SPS configurations at both terminal and network-side devices, enabling activation and de-activation of specific configurations based on sub-group needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If terminal devices in the same sub-group use the same SPS configuration, then configuration management is simplified, but transmission efficiency deteriorates due to inability to meet differentiated service demands
Solution Approach 1:
The patent segments terminal devices into different sub-groups (first sub-group and second sub-group) with different SPS configuration parameters. Each sub-group has its own SPS configuration index, resource allocation, and transmission timing, allowing differentiated service demands to be met while maintaining manageable configuration complexity through structured segmentation.
Solution Approach 2:
The patent applies local quality by assigning different SPS configuration parameters to different sub-groups of terminal devices. Each sub-group receives customized configuration (e.g., different SPS configuration indices, resource allocations, or transmission timing) matched to their specific service demands and channel conditions, optimizing transmission efficiency for each local group.
2Adaptability or versatility
If multiple SPS configurations are activated for different terminal devices, then service differentiation is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic SPS configuration management where the network device can activate or deactivate different SPS configurations for different sub-groups based on varying service demands and channel conditions. The configuration can be dynamically adjusted through network device control, allowing the system to adapt to changing requirements without permanent complex setup.
Solution Approach 2:
The patent creates a universal SPS configuration framework that can serve multiple sub-groups with different requirements using a common set of configuration parameters. The same SPS configuration index can be universally applied to different sub-groups, and the network device can control activation/deactivation across multiple groups, reducing overall system complexity through multi-functional configuration management.
3Productivity
If re-grouping of terminal devices is performed to match service demands, then transmission efficiency is improved, but transmission delay increases due to reconfiguration time
Solution Approach 1:
The patent performs preliminary action by pre-configuring multiple SPS configurations for different sub-groups before transmission needs arise. The network device prepares differentiated SPS configurations in advance for various terminal device groups, so when service demands change, the pre-configured parameters can be quickly activated without time-consuming reconfiguration, thus reducing transmission delay.

AI summary
A semi-persistent scheduling (SPS) transmission indication method and apparatus applied to multi-broadcast scheduling (MBS), includes: a terminal device receives SPS transmission indication signaling sent by a network-side device; and the terminal device obtains, on the basis of the SPS transmission indication signaling, a terminal device sub-group to which an SPS transmission belongs and an SPS transmission state corresponding to the terminal device sub-group to which the SPS transmission belongs.
