UE Relay Service Signaling With RSC Codes for Efficient Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies lack efficient methods for UEs to determine and manage relay services during UE-to-UE (U2U) and UE-to-Network (U2N) relay communication, particularly in Proximity-based Services, as they do not provide clear indications of relay capabilities or services, leading to inefficiencies in relay discovery and service execution.
Innovation Solution
The implementation of a method and apparatus that involves sending and receiving information including UE identifiers and Relay Service Codes (RSCs) to indicate relay services, along with relay and type indications, facilitating accurate determination of relay capabilities and service types among UEs, thereby enhancing relay service management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay communication is introduced for Proximity-based Service, then wireless communication coverage and connectivity are improved, but the complexity of relay service management and identification increases
Solution Approach 1:
The patent uses Relay Service Codes (RSCs) as visual identifiers analogous to color changes, where different RSC values indicate different relay service types. This allows UEs to quickly identify and distinguish relay services without complex management procedures, resolving the contradiction by providing clear service identification while maintaining management simplicity
Solution Approach 2:
The patent segments relay service information into distinct components: relay indication flags and specific RSC values for different service types (e.g., RSC=0 for connectivity, RSC=1 for positioning). This segmentation allows UEs to process only relevant service information, reducing management complexity while supporting diverse relay services
2Productivity
If relay UEs broadcast identifiers of remote UEs, then relay discovery efficiency is improved, but information security and privacy protection deteriorate
Solution Approach 1:
The patent applies preliminary action by having relay UEs obtain explicit broadcast authorization from remote UEs before including their identifiers in relay announcements. This pre-authorization mechanism ensures that identifier broadcasting only occurs when permitted, maintaining security while enabling efficient relay discovery through authorized broadcasts
Solution Approach 2:
The patent implements feedback through relay indication mechanisms where remote UEs provide explicit permission feedback to relay UEs. This feedback loop ensures that identifier broadcasting occurs only with proper authorization, balancing discovery efficiency with information security by making broadcasting contingent on received permission signals
3Adaptability or versatility
If multiple relay services are supported with different RSCs, then service versatility is improved, but signaling overhead increases
Solution Approach 1:
The patent achieves universality by creating a standardized RSC framework where a single signaling field can represent multiple relay service types. Different RSC values within this unified structure indicate different services (connectivity, positioning, etc.), allowing one signaling mechanism to handle diverse services without proportionally increasing overhead
Solution Approach 2:
The patent applies partial action by including only the necessary RSC information in signaling messages. Rather than transmitting complete service descriptions, the system uses compact RSC values that convey essential service type information, reducing signaling overhead while maintaining the ability to support multiple relay service types
