Innovation Solution
A method and apparatus for transmitting radio resource management information through RRC connection across multiple relay terminals to manage radio resources efficiently in multi-hop relay scenarios, including steps for requesting paging messages, system information, measuring link quality, configuring Quality of Service (QoS), and allocating transmission resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-hop relay is used, then the system is simpler to manage, but the coverage enhancement is limited
Solution Approach 1:
The patent segments the relay management function by introducing a designated relay terminal that specifically handles RRC message forwarding. This separates the complex multi-hop relay management from other terminal functions, allowing the system to support multiple relay hops while maintaining manageable complexity through specialized role assignment.
Solution Approach 2:
The patent introduces an intermediary relay terminal that acts as a mediator between the source terminal and the network device. This intermediary forwards RRC messages across multiple hops, enabling extended coverage while the network device maintains centralized control through the relay chain, thus managing complexity through hierarchical intermediation.
2Reliability
If RRC message transmission is implemented in multi-hop relay, then radio resource management is enabled, but the message transmission path becomes more complex
Solution Approach 1:
The patent makes the RRC message transmission mechanism universal across single-hop and multi-hop relay scenarios. The same RRC message structure and processing logic are used regardless of the number of hops, allowing reliable radio resource management while avoiding the need for complex path-specific protocols. The relay terminals uniformly forward messages using standardized procedures.
Solution Approach 2:
The patent implements nested message forwarding where RRC messages are transmitted through a chain of relay terminals. Each relay terminal nested within the communication path forwards the same message structure without needing to understand the complete end-to-end path, simplifying individual terminal complexity while enabling multi-hop transmission.
