Solution Overview

Problem

In communication systems, particularly in scenarios where a receiving device receives information from multiple sending devices, the need for additional signaling interactions to determine device status increases signaling overheads and latency due to shared resource scheduling modes and synchronization sources.

Innovation Solution

A method where a sending device transmits target information related to its supported modes and synchronization sources, allowing a receiving device to learn the sending device's status without additional signaling, thereby reducing overheads and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If additional signaling interaction is performed to learn device status, then the receiving device can determine sending device status accurately, but signaling overheads and scheduling latency are increased

Engineering Contradiction:

Improvedevice status determination accuracyVSAvoidscheduling latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The sending device performs preliminary action by embedding its status information (mode, synchronization source) into the target resource selection itself. The receiving device can directly determine the sending device status by detecting which target resource is used, without needing additional signaling interactions. This preliminary encoding of status information resolves the contradiction by eliminating the need for follow-up signaling while maintaining accurate status determination.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The target resource serves as an intermediary that carries dual functionality: it both transmits the actual data/target information and encodes the sending device status. By using the target resource selection as a mediator, the patent enables status communication without additional signaling overhead, as the resource choice itself conveys the status information to the receiving device.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If multiple sending devices share the same resource pool, then resource utilization is improved, but the receiving device cannot distinguish between different sending device statuses

Engineering Contradiction:

Improveresource utilizationVSAvoiddevice status differentiation

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent applies local quality by making each target resource have a unique characteristic or signature that identifies the sending device's status. Even though multiple sending devices share the same resource pool, each device selects target resources with distinct local qualities (different target resources or different configurations), enabling the receiving device to distinguish between different sending device statuses while maintaining high resource utilization.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The resource pool is segmented into multiple target resources, each associated with specific sending device status characteristics. By dividing the shared resource pool into distinguishable target resources, the patent enables both high resource utilization (through sharing) and status differentiation (through segmentation), as each target resource segment carries information about the sending device's status.

Inventive Principle:

Principle #1Segmentation
