Joint DCI Release for Multiple SPS Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in activating and releasing multiple semi-persistent scheduling configurations and configured grant configurations, leading to increased network overhead and resource consumption due to the need for separate DCI messages for each configuration.
Innovation Solution
Implementing a method to jointly activate and release multiple downlink semi-persistent scheduling configurations and uplink configured grant configurations using a single DCI message, where a bit sequence in the message indicates multiple configurations to be activated or released, either through codepoints or bitmaps, allowing all members of a configuration set to be managed together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate DCI messages are used for each semi-persistent scheduling configuration, then individual configuration management is achieved, but network overhead and resource consumption increase
Solution Approach 1:
The patent combines multiple separate DCI messages into a single joint DCI message that can simultaneously activate or release multiple semi-persistent scheduling configurations. The joint DCI message contains a first indication field for a first SPS configuration and a second indication field for a second SPS configuration, allowing multiple configurations to be managed together in one message, thereby reducing network overhead while maintaining individual configuration control.
2Quantity of substance
If a single DCI message manages multiple configurations, then network overhead is reduced, but message complexity increases
Solution Approach 1:
The joint DCI message is segmented into distinct indication fields, where each field corresponds to a specific SPS configuration. The first indication field manages the first SPS configuration while the second indication field manages the second SPS configuration. This segmentation allows the complex message to be systematically organized and processed, making the complexity manageable through structured field allocation.
Solution Approach 2:
The joint DCI message serves multiple functions simultaneously by incorporating indication fields for multiple SPS configurations. A single DCI message structure is designed to handle activation and release operations for different configurations, making the message structure multi-functional and reducing the need for separate specialized messages for each configuration.
3Productivity
If joint activation and release is implemented, then resource management efficiency is enhanced, but configuration set management complexity increases
Solution Approach 1:
The patent implements dynamic configuration set management where the joint DCI message can flexibly indicate different combinations of SPS configurations for activation or release. The indication fields can be dynamically configured to match the specific set of SPS configurations that need to be managed together, allowing adaptive resource management without rigid fixed structures, thereby enhancing efficiency while managing complexity through flexibility.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message. The UE may map a bit sequence in the single DCI message to a configuration set that includes multiple downlink semi-persistent scheduling configurations or multiple uplink configured grant configurations to be jointly activated or released. Numerous other aspects are provided.
