Terminal Device Resource Pool Selection for Uplink Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future communication systems, contention-based uplink access modes require efficient resource allocation for terminal devices, where existing methods lack flexibility in selecting resource pools without network scheduling, leading to suboptimal resource utilization.
Innovation Solution
A signal transmission method where terminal devices determine a resource pool based on a numerology, acquiring corresponding relationships between numerologies and resource pools, and selecting the appropriate pool using indication information or load measurement to transmit signals efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal devices use fixed resource pool allocation without network scheduling, then access simplicity is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by enabling terminal devices to dynamically select resource pools based on service types and path loss parameters. The resource pool selection is no longer fixed but adapts to changing channel conditions and service requirements, resolving the contradiction between access simplicity and resource utilization efficiency.
Solution Approach 2:
The patent changes the parameter of resource pool selection from a fixed value to a variable determined by service type and path loss conditions. By introducing parameter-based selection criteria, the system achieves both simple access procedures and improved resource utilization, as terminals automatically select appropriate resource pools based on current conditions.
2Device complexity
If terminal devices select resource pools without considering service types and channel conditions, then selection complexity is reduced, but communication performance deteriorates
Solution Approach 1:
The patent introduces parameter-based selection criteria (service type and path loss parameters) to guide resource pool selection. This approach maintains relatively simple selection procedures while significantly improving communication performance by matching resource pools to specific service requirements and channel conditions.
Solution Approach 2:
The patent applies local quality by assigning different resource pools to different service types and path loss conditions. Each service type (e.g., URLLC, eMBB, mMTC) and channel condition receives appropriately tailored resource pool characteristics, improving overall system reliability without requiring complex centralized scheduling.
