Random Access Resource Pools for TA Pre-Compensation Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NTN systems face challenges in determining appropriate random access channel (RACH) resources for terminal devices with and without timing advance (TA) pre-compensation capability, leading to inefficient resource scheduling and utilization.
Innovation Solution
A method and apparatus that configure distinct random access resource pools for terminal devices with and without TA pre-compensation capability, allowing the network device to distinguish and apply targeted resource scheduling policies based on the device's capability, thereby improving scheduling accuracy and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single random access resource pool is used for all terminal devices, then the system is simple to manage, but resource scheduling accuracy deteriorates because devices with and without TA pre-compensation capability cannot be differentiated
Solution Approach 1:
The patent divides the single random access resource pool into two separate resource pools: a first random access resource pool for terminal devices with TA pre-compensation capability and a second random access resource pool for terminal devices without TA pre-compensation capability. This segmentation allows the network device to accurately identify device capabilities through resource pool selection, thereby resolving the contradiction between system simplicity and scheduling accuracy.
2Measurement precision
If separate random access resource pools are configured for terminal devices with and without TA pre-compensation capability, then resource scheduling accuracy is improved, but system complexity increases due to dual resource pool management
Solution Approach 1:
The patent applies local quality by making the resource pool configuration adaptive to the specific capability of terminal devices. Each terminal device type (with or without TA pre-compensation capability) is assigned to a specific resource pool that is optimized for its characteristics. This localized optimization improves scheduling accuracy while keeping the overall system manageable through capability-based classification.
3Ease of manufacture
If random access resources are not differentiated by TA pre-compensation capability, then configuration is simpler, but resource utilization efficiency deteriorates due to inability to apply targeted scheduling policies
Solution Approach 1:
The patent introduces dynamic resource allocation based on terminal device capabilities. The network device dynamically selects which resource pool to assign to each terminal device based on its TA pre-compensation capability. This dynamic approach enables targeted scheduling policies that optimize resource utilization efficiency while maintaining configuration simplicity through automated capability-based assignment.
