Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing slot aggregation methods suffer from low transmission efficiency due to poor flexibility in resource allocation and transmission parameters across slots, leading to suboptimal resource utilization and performance.
Innovation Solution
The method involves setting variable slot intervals, resource allocation, and transmission formats across slots, allowing for dynamic adjustment based on feedback information to optimize resource use and transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If slot aggregation uses fixed resources and transmission parameters across all slots, then implementation is simple, but transmission efficiency is low and flexibility is poor
Solution Approach 1:
The patent applies dynamics by making resources and transmission parameters adjustable across different slots rather than fixed. The base station can dynamically allocate different time-frequency resources, modulation and coding schemes, and power levels for each slot based on channel conditions, transforming the static slot aggregation structure into a flexible dynamic system that adapts to varying transmission requirements
Solution Approach 2:
The patent segments the slot aggregation structure by dividing it into multiple independent slot units, each capable of having independently configured resources and transmission parameters. This segmentation allows the system to treat each slot as a separate configurable entity while maintaining the overall aggregation structure, enabling fine-grained control over transmission characteristics
2Device complexity
If slot aggregation uses fixed number of slots, then configuration is simple, but adaptability to different scenarios is poor
Solution Approach 1:
The patent implements dynamic slot aggregation by allowing the number of aggregated slots to be flexibly adjusted based on transmission requirements. The base station can configure different aggregation depths (K values) for different traffic types, channel conditions, and service requirements, transforming the fixed-slot aggregation into a dynamic structure that adapts to varying scenario demands
Solution Approach 2:
The patent creates a universal slot aggregation framework that can accommodate multiple scenarios through a single flexible configuration mechanism. The same slot aggregation structure can be adapted for different service types (e.g., eMBB, URLLC, mMTC), different channel conditions, and different QoS requirements by simply adjusting parameters rather than requiring separate dedicated structures for each scenario
3Device complexity
If continuous slot aggregation is used, then resource allocation is simple, but resource waste occurs when feedback delays are present
Solution Approach 1:
The patent segments continuous slot aggregation into discrete controllable units by introducing the concept of independent slot configurations within the aggregation. This allows the system to identify and terminate aggregation early when feedback indicates successful reception, preventing waste of remaining aggregated slots while maintaining simple resource allocation through standardized slot units
Solution Approach 2:
The patent incorporates feedback mechanisms that allow the receiving end to inform the transmitting end about successful or failed receptions. Based on this feedback, the base station can dynamically adjust subsequent slot configurations within the aggregation, stopping transmission early when ACK is received or adjusting parameters when NACK is received, thereby avoiding resource waste from unnecessary continuous transmission
4Loss of information
If same transmission parameters are used in all aggregated slots, then control signaling overhead is reduced, but transmission performance is suboptimal
Solution Approach 1:
The patent segments transmission parameters into different configurability levels: some parameters (like aggregation size, slot timing) are configured at the aggregation level to minimize overhead, while other parameters (like modulation scheme, coding rate, power level) can be independently adjusted per slot. This segmented parameter control allows performance optimization without proportionally increasing signaling overhead
Solution Approach 2:
The patent applies local quality by allowing different transmission parameters to be optimized for specific slots based on local channel conditions. Each slot can have tailored modulation and coding schemes, power levels, and resource allocations matched to its specific transmission requirements, while maintaining the overall aggregation structure that keeps control overhead manageable
