Solution Overview

Problem

Existing XR services face challenges in efficiently transmitting data with varying frame sizes using periodic configured grant PUSCH (CG-PUSCH) due to frequent changes in packet body size, leading to potential underutilization of resources and increased energy consumption.

Innovation Solution

Implementing a method where each CG-PUSCH configuration includes multiple CG-PUSCH resources within a period, allowing for continuous time domain allocation to ensure complete data transmission and reduce energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If periodic CG-PUSCH configuration with single resource per period is used, then resource allocation simplicity is maintained, but data transmission completeness deteriorates when frame size varies frequently

Engineering Contradiction:
Improvedata transmission completenessVSAvoidresource configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the CG-PUSCH resources by configuring multiple resources within each periodic allocation. Instead of a single resource per period, the system divides the uplink transmission capacity into multiple discrete CG-PUSCH resources (e.g., multiple time slots or frequency resources) that can be independently selected based on the actual data size of each XR frame, ensuring complete transmission while maintaining structured configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic adaptability into the resource allocation by allowing the network device to flexibly determine the number of CG-PUSCH resources allocated per period based on real-time XR service requirements. The configuration parameter indicating the number of resources can be adjusted dynamically to match varying packet body sizes, enabling the system to adapt to changing data transmission needs without reconfiguring the entire periodic structure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple CG-PUSCH resources are allocated per period, then data transmission completeness improves for large frames, but energy consumption increases due to more frequent transmissions

Engineering Contradiction:
Improvedata transmission completenessVSAvoiduser equipment energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by allocating multiple CG-PUSCH resources per period but not requiring all resources to be used in every transmission. The user equipment can selectively utilize only the necessary number of resources based on the actual data size of each XR frame, avoiding unnecessary transmissions and reducing energy consumption while ensuring sufficient capacity for large frames when needed.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent enables parameter changes by introducing configurable parameters that define the number of CG-PUSCH resources per period and their specific time-frequency locations. These parameters can be adjusted by the network device to optimize the balance between transmission completeness and energy efficiency, allowing the system to adapt resource allocation to match the actual XR service data rate requirements.

Inventive Principle:
Principle #35Parameter changes

3Use of energy by moving object

If single CG-PUSCH resource per period is used, then energy consumption is minimized, but resource utilization efficiency deteriorates when packet body size fluctuates

Engineering Contradiction:
Improveenergy consumptionVSAvoidresource utilization efficiency
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent achieves universality by designing the CG-PUSCH configuration to serve multiple functions: it can handle both small and large XR frames within the same periodic structure. By configuring multiple resources per period with flexible parameters, the system creates a multi-functional allocation scheme that can adapt to varying packet body sizes, improving resource utilization efficiency without requiring separate configuration schemes for different data sizes.

Inventive Principle:
Principle #6Universality (Multi-functionality)
