Wireless Relay Node Indicator for Setup Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-hop relay networks, existing solutions require significant time and resources to set up links between nodes, as each relay node needs to be pre-configured with knowledge of the next node's IP address and routing table, making the initial data transmission process cumbersome and inefficient.
Innovation Solution
A method where a first wireless node transmits payload data to a relaying node with an embedded indicator that includes demodulation reference signal assignments and radio transmission parameters, allowing the relaying node to forward data without prior knowledge of the target node or path, thus eliminating the need for pre-configuration and reducing setup time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay nodes are pre-configured with routing tables and IP address knowledge, then data can be reliably forwarded to the correct destination, but the setup time and resource overhead increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-configuring relay nodes with basic forwarding capabilities and routing information before data transmission begins. The network controller distributes routing tables and destination IP address mappings to relay nodes in advance, so that when data needs to be transmitted, the relay nodes are already prepared to forward packets without requiring time-consuming on-demand route discovery or configuration exchanges.
2Productivity
If relay nodes are pre-configured with routing information, then data transmission can proceed smoothly, but processing resources and configuration overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the network into controlled segments managed by a network controller. Instead of requiring every relay node to maintain complete routing tables for all possible destinations, the network controller segments the routing information and distributes only the necessary portion to each relay node based on its position in the network. This reduces the configuration overhead and processing requirements at individual relay nodes while maintaining overall network productivity.

AI summary
A method performed by a first wireless node for enabling relaying by a relaying wireless node of data intended for reception by a second wireless node. The first wireless node, second wireless node and relaying wireless node each operate in a wireless communications network. The first wireless node transmits (803) a first payload data to the relaying wireless node. The first payload data comprises a second payload data intended for the second wireless node. The first payload data further comprises an indicator, which indicator indicates to the relaying wireless node how to relay the second payload data. The indicator comprises parameters related to radio transmission of the second payload data.
