Multi-Band CSI Report Acquisition in Sidelink Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems support CSI reports only on a single frequency band, limiting the ability of terminals to communicate effectively across multiple frequency bands in sidelink communication.
Innovation Solution
A method and apparatus that enable terminals to establish a unicast connection for exchanging CSI report requests and configuration information, allowing them to determine and transmit CSI reports across multiple frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminals support CSI reports only on a single frequency band, then the system complexity is low, but the communication versatility and adaptability are limited
Solution Approach 1:
The patent segments the frequency band support by introducing frequency band indication information that identifies specific frequency bands (first frequency band and second frequency band) separately. This allows the system to handle multiple frequency bands in a structured, modular way, enabling versatile frequency band support while maintaining manageable system complexity through organized segmentation of frequency resources.
Solution Approach 2:
The patent adds a frequency band dimension to the CSI reporting mechanism by introducing frequency band indication information. This transforms the system from single-frequency-band operation to multi-frequency-band operation by adding the frequency band selection dimension, thereby improving adaptability without proportionally increasing complexity.
2Productivity
If terminals transmit CSI reports across multiple frequency bands, then communication efficiency improves, but information transmission overhead increases
Solution Approach 1:
The patent extracts the frequency band indication information as a separate, dedicated element within the CSI report. By taking out the frequency band identification from the general CSI data and handling it separately, the system can efficiently indicate multiple frequency bands without significantly increasing overall information overhead, while improving communication efficiency through targeted multi-band reporting.
Solution Approach 2:
The patent changes the parameter structure of the CSI report by introducing frequency band indication information that specifies which frequency bands (first or second) should be reported. This parameter change enables efficient multi-frequency-band communication by allowing the system to selectively report on relevant frequency bands based on current communication needs, thereby improving productivity with controlled information overhead.

AI summary
A method for acquiring a channel state information (CSI) report is performed by a first terminal. The method includes: receiving a CSI report request sent by a second terminal, wherein a unicast connection is established between the first terminal and the second terminal; receiving configuration information sent by the second terminal; determining a target frequency band in a plurality of frequency bands; and sending a CSI report of the target frequency band to the second terminal.
