Solution Overview
Problem
In collaborative sensing and hybrid positioning scenarios, the lack of coordination between terminals and network devices regarding frequency-domain resource allocation prevents effective measurement of reference signals.
Innovation Solution
A method and apparatus for transmitting configuration information of reference signals across different communication links, allowing devices outside the primary link to receive and measure these signals, thereby improving measurement performance.
Engineering Contradictions & Design Principles
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 on reference signals cannot be achieved
Solution Approach 1:
The patent segments the frequency-domain resources by introducing a frequency offset that is specific to each terminal's link. This segmentation allows different terminals to use overlapping frequency resources while maintaining orthogonality through the offset, thereby enabling collaborative measurement while reducing interference.
Solution Approach 2:
The patent changes the frequency parameter by applying a link-specific frequency offset to the reference signal. This parameter change allows the reference signal to be transmitted on frequency resources that are not strictly orthogonal across different terminals, enabling collaborative measurement capability while managing interference through controlled frequency shifting.
2Ease of operation
If a network device is unaware of time-frequency resources autonomously selected by a terminal, then terminal autonomy is maintained, but collaborative measurement on reference signal cannot be achieved
Solution Approach 1:
The patent introduces configuration information as an intermediary that carries frequency offset parameters. This intermediary allows the terminal to autonomously select time-frequency resources while the network device becomes aware of the selected resources through the configuration information, enabling collaborative measurement without compromising terminal autonomy.
Solution Approach 2:
The patent applies preliminary action by pre-configuring frequency offset parameters that are associated with specific links. This allows the terminal to autonomously select resources within the pre-configured framework, and the network device to anticipate and plan for the resource selection, thereby enabling collaborative measurement while maintaining terminal autonomy.

AI summary
The present disclosure discloses a configuration method of a reference signal, an apparatus, a device and a storage medium, and relates to the field of mobile communications. The method includes: transmitting configuration information of a reference signal to a target device, where the reference signal is transmitted via a first link, and the target device is a device outside the first link. In the technical solutions provided in the embodiments of the present disclosure, through transmitting the configuration information of the reference signal to the target device, the target device outside the first link where the reference signal is located can obtain the configuration information of the reference signal, so that the target device performs measurement on the reference signal, thereby avoiding a situation where the target device is unable to measure the reference signal, and improving the performance of measuring the reference signal in a collaborative sensing scenario or a hybrid positioning scenario.
