Assisting Node Configuration for Wireless Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring location information for transmitting packets via assisting nodes, particularly in avoiding deactivated or misaligned assisting nodes.
Innovation Solution
A method where a user equipment (UE) identifies a configuration for an assisting node (AN) that includes indications of active time resources and location information indicating communication direction. The UE selects a time resource based on this information and transmits packets accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UE transmits packets through assisting nodes without verifying their active status and directional alignment, then the transmission process is simplified, but communication reliability deteriorates due to potential transmission failures through deactivated or misaligned nodes
Solution Approach 1:
The UE performs preliminary verification of the assisting node's active status and directional alignment before transmitting packets. The UE checks whether the current time falls within the active time window and whether the location information indicates proper directional alignment, preventing transmission failures before they occur.
Solution Approach 2:
The system uses location information and active time indicators as feedback mechanisms to guide the UE's transmission decisions. The UE continuously monitors whether the assisting node is currently active and properly oriented, adjusting its transmission behavior based on this feedback to maintain reliable communication.
2Reliability
If the UE continuously monitors assisting node status and location information to ensure proper packet transmission, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The UE performs monitoring of assisting node status and location information periodically at specific time intervals rather than continuously. The UE checks whether the current time falls within the advertised active time window and verifies directional alignment only when needed, reducing power consumption while maintaining communication reliability.
3Productivity
If the UE transmits packets through assisting nodes with directional communication capabilities, then communication efficiency is improved, but the complexity of selecting appropriate time resources and verifying node alignment increases
Solution Approach 1:
The assisting node provides preliminary information about its active time windows and location/directional characteristics to the UE before packet transmission. This allows the UE to plan and select appropriate time resources in advance without complex real-time decision-making, simplifying the transmission process while maintaining efficiency.

AI summary
Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.
