Uplink Resource Flexibility via Attribute Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE system has limited flexibility in uplink data transmission due to fixed attributes such as TTI length, basic numerology, and SPS configuration, which cannot accommodate diverse service requirements in future communication systems.
Innovation Solution
A data transmission method where a terminal device processes uplink authorization information based on prioritized attributes of overlapping uplink resources, such as TTI length, basic numerology, time interval K2, SPS configuration, or RNTI, to select the most suitable resources for transmission, improving flexibility by allowing partial or complete overlap in time and frequency domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed attributes (TTI length, basic numerology, SPS configuration) are adopted for uplink resources, then system complexity is reduced and ease of operation is improved, but adaptability to diverse service requirements deteriorates
Solution Approach 1:
The patent introduces dynamic resource allocation where uplink resources can have different attributes (TTI lengths, numerologies, SPS configurations) selected based on service requirements. The network device dynamically configures multiple uplink resources with varying attributes, allowing the system to adapt to diverse services while maintaining manageable complexity through structured configuration mechanisms.
Solution Approach 2:
The patent changes key parameters of uplink resources including TTI length, basic numerology, and SPS configuration to create multiple resource types. By varying these parameters, the system can accommodate different service requirements (e.g., low latency vs. high reliability) while the network device manages the complexity of configuring and tracking these multiple parameter sets.
2Adaptability or versatility
If multiple uplink resources with different attributes are allocated, then adaptability to diverse services is improved, but resource conflict and processing complexity increase
Solution Approach 1:
The patent applies local quality by assigning different attributes (TTI lengths, numerologies, SPS configurations) to specific uplink resources based on their intended service usage. Each resource is optimized for its specific purpose, and the terminal device processes them according to service priorities, reducing overall processing complexity by handling resources locally according to their specific requirements rather than uniformly.
Solution Approach 2:
The terminal device autonomously processes multiple uplink resources with different attributes by determining processing orders based on service priorities and resource attributes. This self-service capability reduces network intervention and simplifies overall system complexity while maintaining high service flexibility.
3Productivity
If uplink resources are allowed to overlap in time and frequency domains, then resource utilization efficiency is improved, but interference and transmission reliability may deteriorate
Solution Approach 1:
The patent segments uplink resources into multiple types with different attributes (TTI lengths, numerologies, SPS configurations). By segmenting resources this way, the system can allow temporal and frequency overlap while maintaining transmission reliability through differentiated handling of each resource type according to its specific service requirements and priority.
