Relay UE Multiplexing Remote RRC Messages in 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current relay user equipment (UE) configurations face challenges in efficiently multiplexing multiple remote UE radio resource control (RRC) messages in fifth generation new radio (5G NR) wireless communication systems.
Innovation Solution
The implementation involves a method where a relay UE receives remote UE RRC messages, determines associated remote UE information, and transmits these messages and information to the network entity, enabling multiplexing and establishment of communication contexts for multiple remote UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a relay UE connects multiple remote UEs to the network, then network coverage and resource utilization are improved, but the complexity of multiplexing multiple remote UE RRC messages increases
Solution Approach 1:
The patent segments the multiplexing process into distinct functional components: the relay UE separates message reception from message transmission, the network entity separates message aggregation from context establishment. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while enabling multiple remote UEs to share the relay UE connection.
Solution Approach 2:
The patent introduces the network entity as an intermediary that receives multiplexed RRC messages from the relay UE and performs context establishment for multiple remote UEs. This intermediary role allows the relay UE to focus on efficient message forwarding while the network entity handles the complexity of managing multiple communication contexts, thus resolving the contradiction between improved network utilization and increased multiplexing complexity.
2Loss of substance
If RRC messages from multiple remote UEs are multiplexed through a single relay UE, then signaling overhead is reduced, but message identification and routing difficulty increases
Solution Approach 1:
The patent merges multiple remote UE RRC messages into a single multiplexed message stream transmitted through the relay UE to the network entity. This merging reduces signaling overhead by eliminating redundant transmission channels while the network entity maintains the ability to identify and route messages to the appropriate remote UEs based on message content and context information.
Solution Approach 2:
The patent implements preliminary action by having the network entity pre-establish communication contexts for multiple remote UEs before actual RRC message exchange. This preliminary context establishment includes allocating unique identifiers and routing information, which simplifies subsequent message identification and routing operations, thereby reducing the difficulty of detecting and measuring message origins despite the multiplexed transmission.
