Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless backhaul networks face inefficiencies in resource allocation, leading to delayed traffic and increased costs due to suboptimal communication between nodes, particularly in dense deployments using millimeter wave frequencies.
Innovation Solution
A method and system that enable wireless nodes to autonomously request and select additional resources, such as time, frequency, space, and code resources, to establish connections with new nodes within the network, optimizing resource utilization and reducing latency.

Engineering Contradiction Analysis
1Object-affected harmful factors
If resources are partitioned and allocated to different nodes in a wireless backhaul network, then interference is minimized, but resource utilization efficiency deteriorates and traffic delay increases
Solution Approach 1:
The patent implements dynamic resource allocation where nodes can request and receive additional resources autonomously based on current network conditions and traffic demands. The resource allocation is not static but adapts dynamically through request-response messaging between nodes, allowing the system to optimize resource utilization while maintaining interference minimization benefits.
Solution Approach 2:
Nodes in the wireless backhaul network are empowered to autonomously request additional resources from other nodes without requiring centralized control. Each node can independently identify its resource needs, formulate requests, and select appropriate resources from available options, enabling self-service resource allocation that improves overall network efficiency.
2Object-affected harmful factors
If resources are partitioned and allocated to different nodes in a wireless backhaul network, then interference is minimized, but traffic delay increases
Solution Approach 1:
The dynamic resource allocation mechanism allows nodes to quickly request and obtain additional resources when traffic demands arise, reducing waiting times and traffic delays. The system can adapt resource allocation in real-time based on current network conditions, preventing congestion and minimizing delay while maintaining interference minimization.
Solution Approach 2:
Nodes can proactively request additional resources before traffic congestion occurs or when anticipating increased traffic demands. This preliminary action allows the system to prepare resource allocations in advance, preventing delays before they occur rather than reacting after congestion has developed.
3Productivity
If nodes autonomously request and select additional resources, then resource allocation efficiency improves and latency reduces, but system complexity increases
Solution Approach 1:
While autonomous resource requesting increases node functionality, the patent simplifies the overall system by eliminating the need for complex centralized resource management. Each node independently handles its own resource needs through standardized request-response protocols, distributing complexity across nodes rather than concentrating it in a central controller.
Solution Approach 2:
The patent implements universal request-response messaging protocols that can be used by any node for any resource type (time, frequency, space, code). This multi-functional approach allows a single standardized mechanism to handle diverse resource allocation scenarios, reducing the need for separate specialized protocols for each resource type and thereby managing system complexity.

AI summary
Methods, systems, and devices for wireless communication are described. A first wireless node may establish a wireless connection between the first wireless node and a second wireless node in a wireless backhaul communications network. The first wireless node may identify, at the first wireless node, a need for additional resources for wireless communications with a third wireless node. The first wireless node may transmit a request message to the second wireless node indicating that resources are requested at the first wireless node. The first wireless node may receive an indication of one or more available resources from the second wireless node. The first wireless node may select one or more of the available resources for wireless communications with the third wireless node.
