Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently coordinating measurements and communications among co-located devices, particularly in heterogeneous networks with varying transmit power levels and interference, which can impact network performance and user experience.
Innovation Solution
Implementing a method and apparatus for cooperative measurement and communication among co-located nodes, including identifying and receiving measurement information such as beam, TRP, or cell measurements, and using this information to configure and schedule communications effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooperative measurement is implemented among co-located devices, then network performance and coverage are improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent combines measurement operations across multiple co-located devices into a unified measurement framework. Co-located devices share measurement results and coordinate their measurement activities, effectively merging individual device measurements into a collective measurement system that improves network performance while distributing the coordination burden.
Solution Approach 2:
The patent introduces a coordinating entity or mechanism that acts as an intermediary to manage measurement coordination among co-located devices. This mediator handles the complexity of synchronization and result sharing, allowing individual devices to benefit from cooperative measurement without each device bearing the full coordination overhead.
2Object-affected harmful factors
If measurement information is shared among co-located nodes, then interference is reduced and coverage is improved, but communication overhead increases
Solution Approach 1:
The patent extracts and shares only the essential measurement information needed for interference mitigation among co-located devices, rather than transmitting all raw measurement data. This selective extraction of critical parameters reduces the communication overhead while still achieving the goal of interference reduction and coverage improvement.
Solution Approach 2:
The patent enables each co-located device to apply measurement information locally to its specific transmission and reception operations. By tailoring the application of shared measurement data to local conditions, each device can reduce interference in its immediate environment without requiring excessive communication for coordination.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may identify a set of co-located nodes associated with a co-location condition relative to the node. The node may receive, from the set of co-located nodes, measurement information regarding at least one of: a beam measurement, a transmission reception point (TRP) measurement, or a cell measurement. The node may perform a search based at least in part on the measurement information. Numerous other aspects are described.
