Solution Overview
Problem
Current CSI-RS based RRM measurements face challenges in accurately measuring downlink reference signals across serving and neighbor cells with different bandwidth, center frequency, and time-frequency locations, which hinders effective mobility decision-making.
Innovation Solution
A method where a first device receives configurations for measurements of downlink reference signals from a second and third device, determines necessary information based on its active bandwidth part and the configurations, performs the measurements, and transmits the results to the second device, ensuring comparable measurement accuracy across different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If CSI-RS resources in neighbor cells have different bandwidth, center frequency and time-frequency location from serving cell, then network flexibility and adaptability are improved, but measurement accuracy and comparability deteriorate
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting measurement bandwidth, center frequency, and time-frequency location parameters based on the active bandwidth part and configuration information. This allows the measurement process to adapt to different CSI-RS resource configurations while maintaining accurate and comparable measurement results across serving and neighbor cells.
Solution Approach 2:
The solution implements dynamics by making the measurement configuration adaptive rather than static. The first device determines measurement parameters dynamically based on received configuration information and its active bandwidth part, enabling the system to handle varying CSI-RS resource configurations across different cells while preserving measurement comparability.
2Measurement precision
If measurement configurations are optimized for specific cell conditions, then measurement accuracy for that cell is improved, but measurement comparability across different cells deteriorates
Solution Approach 1:
The patent applies equipotentiality by ensuring that measurement conditions are normalized across different cells. By determining measurement parameters based on the active bandwidth part and configuration information, the system creates equivalent measurement conditions for both serving and neighbor cells, enabling direct comparison of measurement results despite different underlying CSI-RS configurations.
Solution Approach 2:
The solution uses local quality by allowing different measurement parameter configurations for different cells based on their specific conditions, while still maintaining overall comparability. Each cell's measurement is optimized for its local characteristics (bandwidth, frequency, time-location) while the determination mechanism ensures these local optimizations remain comparable across cells.

AI summary
Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method implemented at a first device comprises receiving, from a second device, a first configuration about a first measurement of first downlink reference signals of the second device and a second configuration about a second measurement of second downlink reference signals of a third device; determining, based on an active bandwidth part of the first device and the first and second configurations, first information for the first measurement and second information for the second measurement; determining a first result of the first measurement based on the first information and a second result of the second measurement based on the second information; and transmitting the first result and the second result to the second device. As such, a fair comparison between the first and second results can be made, and thus it is helpful for the second device to make a correct mobility decision.
