Solution Overview

Problem

The increased power consumption in User Equipment (UE) due to the need to monitor multiple resource pools for Proximity Based Services (ProSe) communication, as there is no capability to selectively choose resource pools based on application needs, leading to inefficient energy usage.

Innovation Solution

Implementing a mechanism to synchronize the use of specific resource pools for ProSe communication by using discovery classes, allowing UEs to reduce the number of monitored resource pools based on discovery class information, thereby optimizing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If UEs monitor all resource pools for ProSe communication, then ProSe service coverage is improved, but power consumption increases

Engineering Contradiction:
ImproveProSe service coverageVSAvoidUE power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the resource pools into different discovery classes (Class 1, Class 2, Class 3) based on ProSe application types. UEs are configured to monitor only the resource pools corresponding to their specific application needs rather than all resource pools, thereby reducing power consumption while maintaining necessary service coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning different discovery class configurations to different UEs based on their specific ProSe application requirements. Each UE receives tailored configuration information indicating which discovery classes it should monitor, optimizing power consumption for each UE's specific use case rather than applying a uniform monitoring approach to all UEs.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If UEs monitor multiple resource pools, then ProSe communication versatility is improved, but device complexity increases

Engineering Contradiction:
ImproveProSe communication capabilityVSAvoidUE monitoring complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments ProSe applications into distinct discovery classes (Class 1 for public safety, Class 2 for commercial, Class 3 for personal use). This segmentation simplifies the UE's monitoring task by providing clear, categorized guidance on which resource pools to monitor based on application type, reducing the complexity of managing multiple resource pools while maintaining versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables dynamic configuration where UEs can be assigned different discovery class configurations based on their application requirements. The network can dynamically adjust which discovery classes a UE should monitor, allowing the system to adapt to different service needs without requiring UEs to permanently configure monitoring for all possible resource pools.

Inventive Principle:
Principle #15Dynamics

AI summary

A method, an apparatus, and a computer program product for wireless communication are provided that enable UEs to conserve power while involved in ProSe communication. The apparatus transmits discovery class information for ProSe communication to an A-UE and to an M-UE. The discovery class information may be transmitted from a PF in response to discovery requests. Discovery class rules may be sent from the PF as a part of service authorization. The discovery class information may be transmitted from a ProSe application server as application layer signaling. The A-UE and M-UE may use the discovery class information to select a pool of ProSe resources according to the discovery class information for transmission or monitoring of ProSe communication. The M-UE may use the information to reduce the number of resource pools of resources that are monitored for ProSe communication.
