Solution Overview

Problem

Current methods for indicating measurement and paging resources in wireless communications systems are inefficient, leading to suboptimal power usage and increased signaling overhead.

Innovation Solution

A resource indication method that utilizes a wake-up signal to determine configuration information for measurement and paging resources, allowing terminals to efficiently manage power consumption by implicitly indicating the existence or location of these resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If measurement resources and paging resources are directly indicated by network device via resource indication signaling, then resource configuration is straightforward, but measurement and paging efficiency is low

Engineering Contradiction:

Improvemeasurement and paging efficiencyVSAvoidsignaling overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent extracts the resource indication function from traditional downlink signaling and relocates it to uplink data transmission. The network device determines measurement and paging resources based on characteristics of uplink data (timing, resource allocation, HARQ process number) without sending separate indication signals, thereby reducing signaling overhead while maintaining efficient resource indication

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses the uplink data transmission itself to carry the indication information. The characteristics of the uplink data (such as time domain resource, frequency domain resource, HARQ process number) automatically serve as the basis for determining measurement and paging resources, eliminating the need for separate indication signaling

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If multiple measurement resources and paging resources are provided for terminal selection, then resource flexibility is improved, but power consumption increases due to extensive resource checks

Engineering Contradiction:

Improveresource selection flexibilityVSAvoidterminal power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the resource determination process into distinct stages: uplink data transmission characteristics are first identified, then these characteristics are mapped to specific measurement and paging resources. This segmentation allows the terminal to follow a clear, deterministic path for resource selection based on uplink data properties, reducing unnecessary checks and power consumption

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network device pre-configures multiple measurement resource sets and paging resource sets with different characteristics. When uplink data is transmitted, the terminal can quickly determine which pre-configured resource set to use based on the uplink data characteristics, avoiding the need to evaluate all available resources and thereby reducing power consumption

Inventive Principle:
