Wireless Device Radio Resource Coordination for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in coordinating transmissions across multiple network nodes, leading to interference and reduced capacity due to uncoordinated operations across cell boundaries, especially in heterogeneous coverage models with smaller cells.
Innovation Solution
A wireless device actively coordinates radio resource configurations with multiple network nodes to ensure disjoint resource usage, allowing contemporaneous communication while reducing network node coordination requirements, using techniques such as subframe configuration and radio resource management to prevent conflicts.

Engineering Contradiction Analysis
1Device complexity
If uncoordinated transmission operations are used across multiple network nodes, then device complexity is reduced, but system capacity decreases and interference increases
Solution Approach 1:
The wireless device autonomously determines the radio resource configuration for communicating with multiple network nodes without requiring complex coordination between the network nodes. The device self-manages the resource allocation by selecting configurations that ensure disjoint resource usage, thereby reducing network coordination overhead while maintaining high system capacity.
2Productivity
If coordinated transmission operations are implemented across multiple network nodes, then interference is reduced and system capacity increases, but device complexity and coordination requirements increase
Solution Approach 1:
Instead of having network nodes coordinate with each other to manage radio resources, the invention inverts the approach by having the wireless device determine and manage its own radio resource configuration when communicating with multiple network nodes. This reversal of the coordination paradigm reduces network coordination complexity while achieving the same interference reduction and capacity improvement goals.
3Object-affected harmful factors
If disjoint radio resource configuration is enforced across multiple network nodes, then interference is reduced, but resource utilization efficiency decreases
Solution Approach 1:
The wireless device dynamically selects from multiple available radio resource configurations based on current network conditions and traffic demand. The configuration is not fixed but adapts to changing conditions, allowing the system to maintain disjoint resource usage for interference reduction while optimizing resource utilization efficiency through flexible, condition-based selection.
4Productivity
If multiple radio frequency chains are used to communicate with multiple network nodes simultaneously, then communication efficiency increases, but device complexity and cost increase
Solution Approach 1:
The wireless device uses time-division multiplexing to communicate with multiple network nodes sequentially rather than simultaneously, assigning different time periods (subframes) for communication with different nodes. This periodic action pattern allows efficient multi-node communication using a single radio frequency chain, avoiding the need for multiple concurrent RF chains while maintaining communication efficiency.

AI summary
A method for communication in a wireless telecommunications network is provided. The method comprises coordinating, by a wireless device, with a first network node to identify a first radio resource configuration comprising a first set of radio resources which is used by the wireless device to communicate with the first network node. The first set of radio resources comprises at least one of radio resources in which the wireless device transmits to the first network node, or radio resources in which the wireless device receives from the first network node.
