Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing solution for efficiently sending a Transport Block (TB) using a transmission opportunity in 5G systems, which is crucial for achieving ultra-high reliability and ultra-low latency in communications.
Innovation Solution
The method involves receiving configuration information that indicates a TB is provided with Q transmission opportunities in R consecutive slots, and then sending the TB according to this configuration information, allowing for efficient utilization of transmission opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slot-based aggregation and scheduling-free slot-based repetition are used for ensuring coverage, then reliability is improved, but transmission latency increases due to the fixed slot length structure
Solution Approach 1:
The patent divides the transmission time into mini-slots instead of using fixed slot structures. By segmenting the transmission opportunity into smaller granular units (mini-slots with configurable lengths), the system can achieve both reliable transmission through repetition and reduced latency by transmitting sooner without waiting for complete slot boundaries.
Solution Approach 2:
The patent introduces dynamic mini-slot based repetition where the transmission structure is no longer fixed to slot boundaries but can be dynamically configured. The gNB can flexibly determine the number of mini-slots, their lengths, and spacing based on channel conditions and service requirements, enabling adaptive optimization between reliability and latency.
2Device complexity
If fixed slot length structures are used for TB transmission, then device complexity is reduced, but adaptability to different transmission requirements deteriorates
Solution Approach 1:
The patent enables flexible configuration of mini-slot parameters including length, number of repetitions, and spacing between transmissions. By allowing dynamic adjustment of these parameters based on channel conditions, traffic type, and quality of service requirements, the system achieves high adaptability while maintaining manageable complexity through standardized configuration mechanisms.
3Reliability
If multiple transmission opportunities are provided in consecutive slots, then reliability is improved, but time resource utilization efficiency deteriorates
Solution Approach 1:
The patent moves transmission opportunities from being constrained to slot boundaries into a more flexible time dimension using mini-slots. This allows transmission opportunities to be positioned more efficiently within the time resources, reducing wasted resources at slot boundaries while maintaining multiple transmission opportunities for reliability, thus improving overall time resource utilization.
