Reference Signal Configuration for Collaborative Sensing Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In collaborative sensing scenarios, the frequency-domain resources of different terminals are orthogonal, or a network device is unaware of the time-frequency resource autonomously selected by a terminal, preventing effective collaborative measurement of reference signals.
Innovation Solution
A configuration method for a reference signal is provided, involving the transmission of configuration information via a first link to a target device outside the first link, including time-frequency resource allocation and measurement gap configurations to enable collaborative sensing or hybrid positioning.

Engineering Contradiction Analysis
1Object-affected harmful factors
If frequency-domain resources are allocated orthogonally for different terminals, then interference between terminals is reduced, but collaborative measurement capability is lost
Solution Approach 1:
The patent segments the frequency-domain resources into different types: orthogonal resources for normal communication and non-orthogonal resources specifically allocated for collaborative sensing. This segmentation allows terminals to use orthogonal resources for data transmission while dedicating non-orthogonal resources for collaborative measurement, resolving the contradiction between reducing interference and enabling collaborative measurement capability
Solution Approach 2:
The patent applies local quality by assigning different resource allocation strategies to different functional requirements. For collaborative sensing operations, terminals are allocated specific non-orthogonal frequency resources that enable measurement capability, while other resources maintain orthogonal allocation for interference-free communication. This localized differentiation allows both objectives to coexist
2Adaptability or versatility
If terminals autonomously select time-frequency resources, then resource allocation flexibility is improved, but network device awareness and collaborative measurement are prevented
Solution Approach 1:
The patent implements preliminary action by having the network device pre-allocate and configure specific time-frequency resources for collaborative sensing before terminals autonomously select them. The network device provides configuration information including resource allocation patterns, and terminals autonomously select from these pre-defined options. This ensures the network device maintains awareness of resource usage while terminals retain flexibility in their selection
Solution Approach 2:
The patent establishes a feedback mechanism where terminals report their autonomous resource selections to the network device. The network device receives this feedback and updates its awareness of the time-frequency resources being used by each terminal for collaborative sensing. This feedback loop resolves the information loss by ensuring the network device knows which resources are allocated for collaborative measurement purposes
