Preemption Indication DCI Size Configuration in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently determining the size and starting position of preemption indications in Downlink Control Information (DCI) for User Equipment (UE) in wireless communication systems, particularly in scenarios where these values are not multiples of defined values, leading to potential reconfiguration failures and inefficiencies.
Innovation Solution
Configuring the UE with a size and starting position for DCI corresponding to preemption indications that are integers not multiples of 14, allowing for flexible configuration and transmission of preemption indications using specific bit positions, enabling the UE to correctly interpret and respond to preemption events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size and starting position of DCI for preemption indications are configured as non-multiples of defined values (e.g., 14), then flexibility in configuration and accurate interpretation of preemption events is improved, but device complexity and potential reconfiguration failures increase
Solution Approach 1:
The patent changes the parameters of DCI size and starting position from fixed multiples of defined values to configurable non-multiple values. This allows the system to adapt to different preemption indication requirements while maintaining proper alignment through configured offsets, resolving the contradiction between flexibility and complexity.
Solution Approach 2:
The patent introduces dynamic configurability for DCI size and starting position through RRC signaling. Instead of static fixed values, the system can dynamically adjust these parameters based on network conditions and requirements, enabling flexible preemption indication while managing complexity through standardized configuration procedures.
2Measurement precision
If the DCI size is configured as a non-multiple of the defined value, then accurate preemption indication is achieved, but reconfiguration failures may occur
Solution Approach 1:
The patent introduces an intermediary configuration mechanism through RRC signaling that mediates between the DCI size requirements and the underlying fixed-size constraints. The RRC configuration acts as a buffer layer that translates flexible size requirements into implementable configurations, maintaining both accuracy and reliability.
Solution Approach 2:
The patent performs preliminary configuration of DCI size and starting position through RRC signaling before actual preemption indications are transmitted. This advance configuration ensures that the UE is properly prepared to interpret non-multiple sized DCI messages, preventing reconfiguration failures by establishing the correct interpretation framework beforehand.
3Productivity
If the starting position is configured as a non-multiple of the defined value, then efficient use of bit positions is achieved, but processing complexity increases
Solution Approach 1:
The patent applies local quality by allowing different starting positions for different UEs or different DCI formats. Instead of a universal fixed starting position, each configuration can have its own optimized starting position tailored to specific requirements, improving bit utilization while managing complexity through localized configuration rather than global complexity.
Data Source
AI summary
A method and apparatus are disclosed. In an example, a User Equipment (UE) is configured with a size associated with downlink control information (DCI) corresponding to one or more preemption indications. In some examples, the size is equal to a first value that is not a multiple of a defined value. Alternatively and/or additionally, the UE is configured with a starting position of a field associated with the DCI. The starting position is equal to a second value that is a multiple of the defined value. Alternatively and/or additionally, a first DCI comprising a first preemption indication is transmitted to the UE based upon the size and/or the starting position.
