Multi-Segment PUSCH Transmit Format Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication technologies face challenges in efficiently configuring and managing multi-segment transmissions on physical shared channels, particularly in New Radio (NR) standards, which require precise control over transport block size, redundancy versions, and time domain resource allocation to ensure low latency and high reliability across different service types.
Innovation Solution
The proposed solution involves generating a configuration message that includes transmit format data for multiple segment transmissions on a physical shared channel, such as the physical uplink shared channel (PUSCH). This data includes transport block size determination, redundancy version signaling, and time domain resource allocation, allowing for dynamic and efficient management of multi-segment transmissions.

Engineering Contradiction Analysis
1Productivity
If multi-segment transmission is implemented on physical shared channel, then data transmission efficiency is improved and latency is reduced, but configuration complexity and management difficulty increase
Solution Approach 1:
The transmission is divided into multiple segments where each segment can be independently configured and transmitted. The configuration message includes separate transmit format data for each segment, allowing flexible resource allocation and parallel processing, which improves transmission efficiency while maintaining manageable complexity through modular configuration.
Solution Approach 2:
The system dynamically adjusts transmission parameters including transport block size, redundancy version, and time domain resource allocation for each segment based on channel conditions and service requirements. This dynamic configuration enables optimal performance for different service types (eMBB, URLLC, MTC) without requiring static complex pre-configuration.
2Reliability
If precise control over transport block size and redundancy version is implemented, then transmission reliability is improved, but control complexity increases
Solution Approach 1:
The patent controls transmission reliability by dynamically adjusting key parameters including transport block size, redundancy version, and time domain resource allocation for each segment. These parameter changes are signaled through configuration messages that provide precise control without requiring complex control mechanisms, as the parameters are optimized based on channel conditions and service type.
Solution Approach 2:
The system implements link adaptation based on feedback regarding channel conditions and transmission performance. The configuration messages are adjusted according to feedback information, allowing the system to maintain high reliability through adaptive parameter selection rather than through complex static control mechanisms.
3Productivity
If dynamic resource allocation for multiple segments is implemented, then resource utilization efficiency is improved, but management difficulty increases
Solution Approach 1:
The configuration message structure is designed to be universal and applicable to different service types (eMBB, URLLC, MTC) and different transmission scenarios. The same framework handles transport block size determination, redundancy version signaling, and time domain resource allocation across multiple segments, simplifying management through a unified approach rather than separate management mechanisms for each service type.
Solution Approach 2:
The system manages dynamic resource allocation by changing key parameters (transport block size, redundancy version, time domain resources) through standardized configuration messages. This parameter-based management approach provides efficient resource utilization while keeping management straightforward, as all resource allocation decisions are conveyed through the same message structure regardless of service type or segment number.
