CSI-RS Resource Configuration for Communication Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent understanding of Channel State Information Reference Signal (CSI-RS) resources between network devices and terminals due to the configuration of Subband Full Duplex (SBFD) slots, leading to potential communication quality issues.
Innovation Solution
The terminal determines a first frequency-domain resource capable of receiving downlink transmission and ensures that the count of configurable frequency-domain resource units of the CSI-RS is greater than or equal to a minimum count, aligning with the network device's configuration to maintain consistent understanding and improve communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device configures CSI-RS resources without considering the terminal's downlink reception capability, then the resource configuration flexibility is improved, but the communication reliability deteriorates due to inconsistent understanding between network device and terminal
Solution Approach 1:
The terminal feeds back its downlink reception capability (first frequency-domain resource) to the network device. The network device uses this feedback information to determine the CSI-RS resource configuration, ensuring that the configurable frequency-domain resource units are sufficient for the terminal's actual reception ability. This feedback mechanism resolves the contradiction by enabling adaptive configuration that maintains both flexibility and reliability.
Solution Approach 2:
The network device dynamically adjusts the CSI-RS resource configuration parameters based on the terminal's downlink reception capability. Specifically, it ensures that the count of configurable frequency-domain resource units of the CSI-RS resource is greater than or equal to the minimum of a first count (downlink reception capability) and a second count (frequency-domain resource units occupied by first frequency-domain resource). This parameter adjustment resolves the contradiction between configuration flexibility and communication reliability.
2Device complexity
If the count of configurable frequency-domain resource units of CSI-RS resource is insufficient, then the device complexity is reduced, but the communication quality deteriorates due to resource mismatch
Solution Approach 1:
The terminal determines its downlink reception capability in advance and communicates this information to the network device. The network device then pre-configures the CSI-RS resource with sufficient frequency-domain resource units based on this advance information. This preliminary action ensures that the resource configuration is appropriate from the start, avoiding communication quality issues while maintaining reasonable device complexity.
Solution Approach 2:
The network device dynamically adjusts the CSI-RS resource configuration parameters based on the terminal's downlink reception capability. It ensures that the count of configurable frequency-domain resource units is greater than or equal to the minimum of the first count (downlink reception capability) and second count (frequency-domain resource units occupied by first frequency-domain resource). This parameter optimization resolves the contradiction between device complexity and communication quality.
3Ease of operation
If the network device configures CSI-RS resources without considering terminal's downlink reception capability, then the ease of operation is improved, but the measurement precision deteriorates due to resource inconsistency
Solution Approach 1:
The terminal provides feedback about its downlink reception capability to the network device. This feedback enables the network device to configure CSI-RS resources that match the terminal's actual reception ability, ensuring consistent understanding of the resources between both parties. The feedback mechanism maintains ease of operation while improving measurement precision through informed configuration.
Solution Approach 2:
The network device adjusts the CSI-RS resource configuration parameters based on the terminal's downlink reception capability feedback. By ensuring that the count of configurable frequency-domain resource units is sufficient, the network device achieves consistent resource understanding between itself and the terminal, resolving the contradiction between ease of operation and measurement precision.

AI summary
The present disclosure relates to the technical field of communications, and specifically to method for determining resources and apparatuses, a communication apparatus and a storage medium, a method for determining resource comprising: receiving a channel state information reference signal (CSI-RS), the count of configurable frequency-domain resource units of a channel state information reference signal resource being greater than or equal to the minimum of a first count and a second count, and the second count being the count of the frequency-domain resource units occupied by a first frequency-domain resource capable of receiving downlink transmission. In the present disclosure, a terminal can receive the CSI-RS, and determine that the count of the configurable frequency-domain resource units of the CSI-RS is greater than or equal to the minimum of the first count and the second count. The count of the frequency-domain resource units of the CSI-RS resource configured by a network device for the terminal is not less than the minimum of the first count and the second count. Therefore, the present disclosure helps to ensure that the network device and the terminal have the consistent understanding of the CSI-RS resource, so as to ensure the quality of subsequent communication between the network device and the terminal.
