Distributed Unit Resource Pattern Indication for Wireless Network Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resource patterns in wireless networks, particularly in identifying and utilizing non-available resources to optimize communication processes, leading to potential interference and resource wastage.
Innovation Solution
A method where a first node in a wireless network transmits an indication of a suggested resource pattern to a central unit or parent node, allowing for the cancellation of communications using non-available resources, skipping downlink measurements, or extending evaluation periods to conserve resources and improve communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If resource patterns are not optimized and non-available resources are not identified, then communication can proceed without coordination, but resource wastage and interference increase
Solution Approach 1:
The DU transmits the suggested resource pattern indication to the CU in advance, before actual resource allocation and communication occur. This preliminary action allows the CU to identify non-available resources and adjust resource patterns proactively, preventing resource wastage and interference before they happen, rather than reacting to problems after they occur.
Solution Approach 2:
The system establishes a feedback loop where the DU provides resource pattern suggestions to the CU, and the CU uses this information to optimize resource allocation. The CU receives the indication and processes it to determine final resource patterns, creating a closed-loop control system that continuously improves resource utilization based on actual network conditions and DU recommendations.
2Productivity
If all communications are transmitted and received without resource optimization, then communication processes are simple, but interference and resource inefficiency increase
Solution Approach 1:
The resource pattern indication is segmented into specific format elements that can be independently processed. The indication includes specific fields for resource pattern information, allowing the CU to parse and process only the relevant portions needed for optimization, rather than handling entire communication streams. This segmentation enables efficient resource management without overwhelming system complexity.
Solution Approach 2:
The system changes the parameter representation of resources by introducing a suggested resource pattern indication with specific formats that encode resource availability information. This parameter transformation allows the CU to efficiently interpret resource patterns and make optimization decisions based on structured data, improving communication efficiency through systematic parameter management.
3Reliability
If non-available resources are not identified, then resource allocation is straightforward, but interference and communication failures increase
Solution Approach 1:
The DU transmits the suggested resource pattern indication to the CU in advance, before actual resource allocation and communication occur. This preliminary action allows the CU to identify non-available resources and adjust resource patterns proactively, preventing resource wastage and interference before they happen, rather than reacting to problems after they occur.
Solution Approach 2:
The system takes preliminary anti-action by identifying and marking non-available resources in advance through the resource pattern indication. By proactively preventing the use of unavailable resources through the indication mechanism, the system avoids interference and communication failures that would occur if those resources were attempted to be used, thus improving reliability without requiring complex real-time detection systems.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.
