IAB Node Slot Format Configuration for Child Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not provide a solution for configuring a slot format for communication between a base station function of an Integrated Access and Backhaul (IAB) node and a child node in a relay network, which is essential for ensuring normal communication.
Innovation Solution
A method is provided to configure a slot format for communication between an IAB node and a child node by determining the slot format based on configuration information received from a parent node, which includes modifying specific slots to optimize communication, allowing the IAB node to communicate effectively with the child node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slot format configuration is not provided for IAB node base station function communication with child node, then the system complexity remains low, but communication between IAB node and child node cannot be established
Solution Approach 1:
The patent introduces configuration information as an intermediary element that carries slot format parameters from the parent node to the IAB node. This mediator structure enables communication establishment without requiring complex direct negotiation between IAB node and child node, resolving the contradiction by providing a standardized configuration mechanism.
Solution Approach 2:
The slot format configuration is performed in advance through pre-configured parameters received from the parent node before actual communication begins. This preliminary action establishes the communication framework beforehand, ensuring reliable communication while avoiding complex real-time configuration decisions.
2Productivity
If slot formats are modified to optimize communication, then communication efficiency improves, but configuration complexity increases
Solution Approach 1:
The patent enables dynamic slot format modification where the IAB node can adjust slot formats based on received configuration information and communication requirements. This dynamic adjustment optimizes communication efficiency while the system manages complexity through structured configuration parameters and standardized modification procedures.
Solution Approach 2:
The patent modifies communication parameters by changing slot format configurations based on received configuration information. By systematically changing parameters like slot duration, symbol allocation, and timing structures, the system optimizes communication efficiency while maintaining manageable complexity through parameter-based control.
3Reliability
If slot format configuration is implemented for all slots, then communication reliability improves, but processing time and complexity increase
Solution Approach 1:
The patent implements slot format configuration selectively rather than uniformly for all slots. Configuration information applies to specific slot sets or subsets where needed, providing sufficient communication reliability for critical slots while reducing processing time and complexity by avoiding unnecessary configuration of all slots.
Solution Approach 2:
The patent divides slot configuration into separate manageable sets, allowing independent configuration of different slot groups. This segmentation enables the system to configure only the necessary slots for reliable communication while leaving other slots with default or simpler configurations, reducing overall processing time and complexity.

AI summary
Example embodiments of this application provide a slot format configuration method. The method includes: a second node sends first configuration information to a first node, where the second node is a parent node of the first node; the first node determines a slot format of each slot in a first set of slots based on the first configuration information, where the first set of slots includes slots that are used for communication between the first node and a third node in one or more periods, and the third node is a child IAB node of the first node or a terminal device served by the first node; and the first node modifies slot formats of some slots in the first set of slots to obtain modified slot formats of these slots.
