Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5G relay communication systems face challenges in configuring relay nodes with limited capabilities and lack defined protocol stacks, preventing network nodes from effectively managing relay communications.
Innovation Solution
A synergetic communication method where network nodes generate and transmit scheduling configurations based on user equipment (UE) capability information to relay nodes, allowing for differentiated configurations and enabling efficient communication through aggregated groups, including L0, L1, and L2 relay nodes.

1Area of stationary object
If relay nodes with limited capability (L0/L1) are deployed to extend network coverage, then network coverage and accessibility are improved, but the network node cannot obtain relay node capability information and thus cannot configure appropriate parameters
Solution Approach 1:
The UE acts as an intermediary that collects capability information from relay nodes and transmits it to the network node. This mediator resolves the information asymmetry problem where the network node cannot directly obtain relay node capabilities, enabling proper configuration while maintaining extended network coverage through L0/L1 relay nodes.
2Productivity
If differentiated configurations are provided for different relay nodes in an aggregated group, then communication efficiency is improved, but the complexity of managing multiple protocol stacks and configurations increases
Solution Approach 1:
The system segments the relay communication into different protocol stack types (first type for L2 relays, second type for L0/L1 relays) with differentiated configurations. This segmentation enables optimized communication efficiency for each relay type while managing complexity through structured separation of configuration protocols.
Solution Approach 2:
Different configuration parameters and protocol stack types are applied locally to different relay nodes based on their specific capabilities. L2 relay nodes receive one type of configuration while L0/L1 relay nodes receive another type, allowing each relay node to be optimally configured for its specific functionality rather than using a uniform configuration approach.

AI summary
A synergetic communication method for relay node configuration and protocol stacks is proposed. A network node may generate a scheduling which indicates the relay node configurations associated with an aggregated group based on the capability information from a user equipment (UE). The scheduling may comprise different configurations for the relay nodes in the aggregated group. In addition, the network node may transmit or schedule the scheduling for controlling the aggregated group to the UE. The UE may transmit the capability information associated with the relay node(s) in the aggregated group to the network node. Therefore, the network node is able to configure the configuration for the relay node with limited capability.
