Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently establishing and managing node-to-node communication links, particularly in densely deployed millimeter wave networks, where existing methods lack effective coordination and resource allocation for directional communication between nodes.
Innovation Solution
An access node determines and configures communication link settings, including directional transmission beams, resources, and modulation schemes, based on measurements from nodes, to establish and manage communication links between nodes, enabling efficient data and control information transfer.

Engineering Contradiction Analysis
1Speed
If nodes establish direct node-to-node communication links without access node coordination, then communication speed and latency are improved, but system reliability and resource allocation efficiency deteriorate due to lack of centralized management
Solution Approach 1:
The access node serves as an intermediary that coordinates link establishment between candidate nodes. It receives establishment requests, performs suitability evaluations based on system state and measurements, and provides configuration information to enable reliable direct communication while maintaining centralized control for system reliability.
2Reliability
If access node provides centralized configuration for node-to-node links, then link establishment reliability is improved, but system complexity and signaling overhead increase
Solution Approach 1:
Candidate nodes perform self-evaluation of link suitability based on measurements and configured parameters provided by the access node. The nodes autonomously determine whether to establish links and configure their own transmission parameters, reducing the access node's coordination burden and system overall complexity while maintaining reliability through controlled autonomy.
3Productivity
If directional beams are used for node-to-node communication, then communication capacity and interference reduction are improved, but beam alignment complexity and measurement requirements increase
Solution Approach 1:
The access node configures candidate nodes with directional beam parameters and measurement configurations before link establishment. Reference signals are transmitted in advance using configured beams, allowing nodes to perform measurements and identify optimal beam directions prior to formal link setup, reducing alignment complexity during actual communication.

AI summary
Methods, systems, and devices for wireless communication are described that provide for establishment of communication links between nodes in a wireless network, in which an access node (e.g., a node that provides access to a core network) may provide a communication link configuration and resources for communications between multiple nodes. In some cases, an access node may receive a request from a first node to establish a communication link with a second node. The communication link may be, for example, a directional transmission beam that carries data or control information, or a combination thereof, between the first node and the second node. The access node may determine the communication link configuration based on one or more link measurements provided by the first node or second node, and provide the configuration information to one or both of the first node or the second node.
