Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The utilization efficiency of resources is not optimized when a secondary cell group (SCG) is in activated or deactivated states in dual connectivity scenarios, leading to inefficient resource allocation.

Innovation Solution

A method and apparatus for information indication that dynamically adjusts the behavior of a terminal device based on the state of the SCG, including power control, header compression, PDCCH blind detection, measurement periods, and RRM measurement, through the use of indication information to optimize resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the SCG occupies resources in deactivated state, then the terminal device can quickly activate the SCG, but resource utilization efficiency deteriorates

Engineering Contradiction:

ImproveSCG activation speedVSAvoidresource utilization efficiency

Core Design Contradiction:

SpeedVSProductivity

Solution Approach 1:

The patent applies dynamics by making the resource allocation dynamic based on SCG state. Different indication information is sent to the terminal device depending on whether the SCG is activated or deactivated, allowing the system to adapt resource occupation behavior to the current state, thus resolving the contradiction between maintaining quick activation capability and improving resource utilization efficiency.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the terminal device performs all operations regardless of SCG state, then operational completeness is maintained, but energy consumption increases

Engineering Contradiction:

Improveoperational completenessVSAvoidterminal device energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by making operations conditional on the SCG state. The terminal device performs different sets of operations depending on whether the SCG is activated or deactivated. Specifically, certain operations are skipped or modified when the SCG is deactivated, reducing energy consumption while maintaining operational completeness when needed.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the SCG uses different resources in activated and deactivated states, then resource allocation flexibility improves, but system complexity increases

Engineering Contradiction:

Improveresource allocation flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses dynamics to manage the complexity-adaptability tradeoff. By dynamically adjusting resource allocation based on SCG state through indication information, the system achieves flexible resource allocation without permanently increasing complexity. The complexity is managed through state-dependent configuration rather than permanent dual-resource structures.

Inventive Principle:

Principle #15Dynamics
