Dynamic Beam Report Indication for CSI Resource Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in optimizing beam reporting and channel state information (CSI) transmission, leading to inefficiencies in resource usage and coordination between wireless devices and base stations.
Innovation Solution
Implementing a dynamic beam report mechanism where wireless devices transmit control messages based on additional information in downlink control information (DCI), determining whether to send reports to enhance the likelihood of successful transmission and improve resource utilization and coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beam reports and CSI reports are transmitted periodically or aperiodically without dynamic indication, then the reporting mechanism is simple to implement, but resource usage efficiency deteriorates and coordination between wireless device and base station is improved
Solution Approach 1:
The patent implements dynamic beam report indication where the base station sends DCI messages with additional information fields that dynamically control whether the wireless device should transmit beam reports or CSI reports. This dynamic indication mechanism allows the system to adapt reporting behavior based on current channel conditions and network requirements, thereby improving resource usage efficiency by avoiding unnecessary reports while maintaining coordination through controlled flexibility.
Solution Approach 2:
The patent changes the parameter of report transmission by introducing an additional information field in DCI that can take different values to indicate different reporting behaviors. By modifying this parameter dynamically, the system can switch between different reporting modes (beam report, CSI report, or no report) without changing the overall reporting mechanism structure, thus improving resource efficiency while maintaining implementation simplicity.
2Reliability
If beam reports are transmitted without dynamic indication, then the coordination between wireless device and base station is maintained, but the likelihood of successful report transmission deteriorates and resource usage efficiency is improved
Solution Approach 1:
The patent implements a feedback mechanism where the base station monitors channel conditions and sends DCI messages with additional information fields that indicate whether beam reports or CSI reports should be transmitted. This feedback loop allows the base station to request reports only when channel conditions are favorable and the report is likely to be successful, thereby improving transmission reliability while maintaining resource usage efficiency through conditional reporting.
Solution Approach 2:
The patent applies preliminary action by having the base station assess channel conditions and send indication information in advance before the wireless device transmits beam reports or CSI reports. This preliminary indication allows the wireless device to prepare and transmit reports only when conditions are favorable, improving the likelihood of successful transmission while avoiding wasteful resource usage when conditions are poor.

AI summary
A wireless device may communicate with a base station. CSI reporting may be initiated by a wireless device. Uplink resource allocation for the CSI reporting may be provided by a base station via downlink control information (DCI). Information in the DCI may indicate whether the wireless device is to transmit a CSI report.
