Solution Overview

Problem

Current communication technologies face challenges in determining whether User Equipment (UE) supports Proximity Services (ProSe) capabilities, leading to inefficient resource allocation and interference between ProSe and cellular network services.

Innovation Solution

A method and apparatus for reporting and processing information about ProSe supporting capabilities, where a first communication node determines and reports indication information to a second communication node, including details on supported bands, transmission capabilities, and resource allocation modes, enabling effective resource allocation and minimizing interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base station does not know whether the terminal is monitoring ProSe services, then the terminal can monitor ProSe services, but the base station schedules terminal unicast resources which interferes with ProSe monitoring services

Engineering Contradiction:
ImproveProSe monitoring service reliabilityVSAvoidInterference between unicast resource scheduling and ProSe monitoring
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The terminal reports its ProSe monitoring capability to the base station before the base station schedules unicast resources. This preliminary action allows the base station to have advance knowledge of the terminal's ProSe monitoring status, enabling it to schedule unicast resources in a way that avoids interfering with ProSe monitoring services.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal provides feedback information to the base station regarding its ProSe monitoring capability and status. This feedback mechanism enables the base station to adjust its resource scheduling decisions based on the terminal's current state, thereby preventing interference between unicast resource allocation and ProSe monitoring activities.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the UE reports detailed ProSe capability information, then the base station can accurately allocate resources, but the signaling overhead increases

Engineering Contradiction:
ImproveProSe capability information accuracyVSAvoidSignaling overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies local quality by selectively reporting only the specific ProSe capability information that is relevant to the current communication context. Instead of reporting all possible ProSe capabilities, the terminal reports only those capabilities that are locally relevant to the base station's resource allocation decisions, thereby reducing signaling overhead while maintaining the necessary precision for accurate resource allocation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The terminal reports partial ProSe capability information - specifically, only the portion of capability information that is sufficient for the base station to make accurate resource allocation decisions. This partial action approach avoids the excessive signaling overhead that would result from reporting complete and detailed ProSe capability information, while still achieving the goal of accurate resource allocation.

Inventive Principle:
Principle #16Partial or excessive action
