Access Stratum Leader Terminal Identification via Mapped Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies, specifically in new radio (NR) systems, lack a standardized method for terminals to perceive the leader terminal within a terminal apparatus group, leading to inefficiencies in resource allocation and group management.
Innovation Solution
A method where a first communications apparatus sends specific information to a second communications apparatus within the same group, using access stratum (AS) messages, to identify and indicate the leader terminal, utilizing mapping relationships between upper-layer identifiers and physical or V2X layer identifiers, allowing the second apparatus to determine and recognize the leader terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a leader terminal is configured to assist the network device in allocating resources to member terminals, then resource allocation efficiency is improved, but the mechanism for perceiving and identifying the leader terminal is not standardized
Solution Approach 1:
The patent introduces an intermediary identification mechanism where the leader terminal's identity is conveyed through mapped identifiers (AS identifier, V2X layer identifier) that act as mediators between the physical layer communication and the upper-layer group management functions. This standardized intermediary mechanism enables efficient resource allocation while maintaining clear leader perception.
2Measurement precision
If mapping relationships between upper-layer identifiers and physical layer identifiers are established, then leader terminal identification precision is improved, but information overhead increases
Solution Approach 1:
The patent creates copies of identifier information across different layers (upper-layer terminal identifier, AS identifier, V2X layer identifier) where each copy serves a specific function. This copying mechanism ensures precise leader identification at each layer while the identifiers are derived from the same source information, avoiding redundant information transmission.
Solution Approach 2:
The mapping relationships between identifiers are established in advance through pre-configuration or preliminary signaling before the actual leader perception is needed. This preliminary action ensures that when resource allocation or group management operations occur, the identification mechanism is already in place without requiring additional real-time information exchange.
Data Source
AI summary
Terminal apparatus identification methods and apparatuses are described. An access stratum (AS) of a first communications apparatus sends first information to an AS of a second communications apparatus. The AS of the second terminal apparatus may identify a leader terminal apparatus based on the first information, so as to implement perception of the leader terminal.
