WAB Node Resource Coordination for Non-Overlapping Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, interference occurs between WAB-NE and WAB-MT components due to uncoordinated use of overlapping time-frequency resources, leading to inefficiencies and potential self-interference.
Innovation Solution
The WAB-MT establishes a wireless connection with a base station to receive signaling that configures resources for communications, selecting non-overlapping resources to avoid interference and coordinating resource usage to reduce or prevent multiplexing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If WAB-NE and WAB-MT components use overlapping time-frequency resources independently, then each component can utilize available resources for communication, but interference occurs between the components leading to reduced system reliability
Solution Approach 1:
The patent introduces a base station as an intermediary that coordinates resource allocation between WAB-NE and WAB-MT components. The base station receives resource requests from both components and assigns non-overlapping time-frequency resources, preventing direct interference while maintaining high resource utilization. This mediator approach resolves the contradiction by centralizing resource management.
Solution Approach 2:
The patent implements dynamic resource configuration where the base station continuously monitors and adjusts resource allocation based on current communication needs. Resources are dynamically assigned to WAB-NE or WAB-MT components depending on traffic conditions, ensuring optimal utilization without persistent interference. This dynamic approach allows the system to adapt resource usage in real-time.
2Reliability
If WAB-NE and WAB-MT components use non-overlapping resources through coordination, then interference is reduced improving reliability, but resource utilization efficiency decreases due to conservative allocation
Solution Approach 1:
The patent applies preliminary action by having the base station pre-configure resource allocations for WAB-NE and WAB-MT components before interference occurs. Resource patterns are established in advance based on predicted traffic needs, allowing components to operate reliably without real-time negotiation overhead. This preliminary configuration ensures non-overlapping resources while maintaining high utilization through accurate predictions.
3Reliability
If centralized resource configuration is implemented at the base station, then resource coordination and interference prevention are improved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent segments resource configuration into different levels: the base station handles high-level resource pattern configuration, while individual WAB-NE and WAB-MT components manage their own specific resource usage within those patterns. This segmentation reduces signaling overhead by distributing management responsibilities, maintaining reliable coordination without excessive centralization complexity.

AI summary
Various aspects of the present disclosure relate to configuring resources for wireless communications at a node. An apparatus, such as a node (e.g., a wireless access and backhaul (WAB) node), uses a first component to establish a wireless connection between a second component of the node and a first base station, the second component of the node including a second base station. The node receives first signaling from the first base station and via the wireless connection that configures resources for communications between the node and one or more devices. The node performs (e.g., transmits or receives) the communications between the node and the one or more devices using at least a portion of the resources. The devices can include the first base station and/or one or more user equipment (UEs).
