Type0 PUSCH Resource Configuration for Controlled PAPR Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular mobile communication systems, the varying peak-to-average power ratios (PAPRs) of Type0 PUSCH resources lead to increased complexity and cost in UE design due to large differences between maximum and minimum PAPRs, particularly affecting lightweight UEs with simpler structures.
Innovation Solution
Configuring a resource set of Type0 PUSCH resources with a limited difference range between maximum and minimum PAPRs, allowing the base station to select resources within this range, and using mask processing to adjust bitmaps based on UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Type0 PUSCH resources are configured with wide PAPR range to provide more resource options, then resource allocation flexibility is improved, but UE design complexity and cost increase
Solution Approach 1:
The patent applies parameter changes by configuring Type0 PUSCH resources with controlled PAPR differences. Specifically, the base station configures resource sets where the difference between maximum and minimum PAPR values is limited to within a first difference range, thereby changing the PAPR parameter distribution to balance resource flexibility with UE design simplicity.
Solution Approach 2:
The patent introduces dynamic adaptability through the second difference range, which is determined based on UE capability information. The base station can dynamically adjust the PAPR difference range according to different UE types (lightweight vs. conventional), allowing the system to adapt resource configuration to specific device capabilities while maintaining overall flexibility.
2Adaptability or versatility
If Type0 PUSCH resources are configured with wide PAPR range to meet diverse signal requirements, then signal amplification coverage is improved, but UE cost increases
Solution Approach 1:
The patent controls the PAPR parameter range by limiting the difference between maximum and minimum PAPR values to within a first difference range for configured Type0 PUSCH resources. This parameter control ensures that signal amplification requirements remain within manageable bounds, reducing UE manufacturing cost while maintaining adequate signal coverage through proper resource selection.
Solution Approach 2:
The patent enables dynamic adaptation to UE capabilities by determining the second difference range based on reported UE information. For lightweight UEs with cost constraints, a narrower PAPR range is enforced, while conventional UEs can utilize wider ranges, thereby optimizing the balance between signal amplification coverage and manufacturing cost for different device categories.
3Productivity
If base station selects Type0 PUSCH resources without PAPR constraints to maximize resource utilization, then resource utilization efficiency is improved, but UE performance variability increases
Solution Approach 1:
The patent enforces PAPR parameter constraints by configuring resource sets where the difference between maximum and minimum PAPR values does not exceed a first difference range. This ensures that regardless of which resource is selected for allocation, the UE experiences consistent performance characteristics, maintaining reliability while allowing the base station to freely select from the configured resource set for efficient resource utilization.

AI summary
A resource configuration method, apparatus, a communication device and a storage medium that improve the resource utilization in a wireless network. The resource utilization of the wireless network is improved by configuring a resource set of a physical uplink shared channel (PUSCH), the resource set comprises at least one Type0 PUSCH resource, and a difference between a maximum value of a peak-to-average power ratio (PAPR) corresponding to each Type0 PUSCH resource and a minimum value of the PAPR in the configured resource set does not exceed a first difference range.
