Solution Overview

Problem

In communication technologies, terminals often skip channel state information reporting when no service is available for a long time, leading to beam management issues and potential terminal or link failures.

Innovation Solution

A processing method and device that allow terminals to report channel state information based on a configured report configuration, even when not monitoring a physical downlink control channel within a specified onduration, and a network device to send signaling indicating these configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the terminal skips the onduration timer to save power, then power consumption is reduced, but channel state information reporting cannot be performed leading to beam management failure

Engineering Contradiction:

Improvepower consumptionVSAvoidbeam management reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent segments channel state information reporting into two distinct modes: periodic reporting (triggered by onduration timer) and aperiodic reporting (triggered by downlink data reception). This segmentation allows the terminal to perform reporting only when necessary, avoiding continuous reporting while ensuring beam management reliability is maintained through event-driven reporting opportunities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes periodic onduration timers as a trigger mechanism for channel state information reporting. When the terminal wakes up at periodic intervals defined by the onduration timer, it performs channel state information reporting if downlink data is received, creating a periodic reporting pattern that balances power savings with beam management requirements.

Inventive Principle:

Principle #19Periodic action

2Reliability

If the terminal monitors PDCCH within onduration, then channel state information reporting can be performed, but power consumption increases

Engineering Contradiction:

Improvechannel state information reporting reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts the channel state information reporting function from the mandatory periodic onduration timer mechanism and couples it with downlink data reception events. Instead of requiring the terminal to always monitor PDCCH and perform reporting during onduration, the solution extracts reporting to occur only when downlink data is actually received, reducing unnecessary power consumption while maintaining reporting reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the triggering parameter for channel state information reporting from time-based (onduration timer expiration) to event-based (downlink data reception). This parameter change allows the reporting mechanism to adapt to actual service conditions, performing reporting only when data transmission occurs, thereby reducing power consumption while ensuring reporting reliability when needed.
