Dynamic DCI Field Mapping for Multi-Function UE Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downlink control information (DCI) in wireless communications systems is inflexible, as it can only indicate one function per piece, limiting its adaptability and efficiency in managing multiple user equipment functions.
Innovation Solution
The method involves configuring DCI with indication information for the location and function of target fields, allowing multiple functions to be indicated per piece of DCI, enhancing flexibility by dynamically adjusting the functions based on user equipment state and carrier information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one piece of DCI is used to indicate one function, then the structure is simple and easy to implement, but the flexibility and adaptability are poor
Solution Approach 1:
The patent applies multi-functionality by enabling a single DCI to indicate multiple functions through configuration information that maps fields to different functions based on UE state and carrier information. The DCI structure remains the same, but its interpretation changes dynamically, allowing one DCI to serve multiple purposes such as wake-up indication, sleep indication, and resource allocation simultaneously.
Solution Approach 2:
The patent implements dynamics by making the function indication of DCI fields configurable and changeable based on UE state and carrier information. The mapping between fields and functions is not fixed but dynamically adjusted through configuration information, allowing the system to adapt to different operational scenarios without changing the physical DCI structure.
2Adaptability or versatility
If multiple fields in DCI are used to indicate multiple UEs, then more UEs can be managed, but one DCI can only indicate one function reducing flexibility
Solution Approach 1:
The patent enables each field in the DCI to serve multiple functions by configuring the mapping between fields and functions based on UE state and carrier information. This allows a single DCI to simultaneously indicate wake-up status, sleep status, and resource allocation for multiple UEs, significantly improving function indication capability without requiring additional DCI transmissions.
Solution Approach 2:
The patent merges multiple function indications into a single DCI transmission by configuring fields to carry both UE identification and function information. This combining approach allows the system to manage multiple UEs with multiple functions simultaneously, improving productivity by reducing the number of separate DCI transmissions needed.
3Adaptability or versatility
If DCI structure is fixed, then implementation is simple, but adaptability to different UE states and carriers is limited
Solution Approach 1:
The patent implements dynamics by introducing configurable field mapping that adapts to different UE states and carrier conditions. The DCI structure itself remains fixed, but the interpretation and mapping of fields are dynamically configured based on UE state and carrier information, enabling adaptability without complicating the physical structure.
Solution Approach 2:
The patent applies parameter changes by modifying the functional mapping parameters of DCI fields based on UE state and carrier information. Instead of changing the physical DCI structure, the system changes the interpretation parameters through configuration information, allowing the same DCI to adapt to different scenarios while maintaining implementation simplicity.
