CSI-RS Burst Pattern Scheduling for Multi-Time CSI Feedback

The patent segments the CSI measurement process into multiple independent CSI-RS resources within burst patterns, allowing parallel measurement of channel and interference across different time instances. This segmentation enables the system to capture multi-dimensional channel state information without requiring a single complex measurement system, thereby improving measurement precision while maintaining manageable system complexity through modular resource configuration.

The patent introduces the time dimension by configuring CSI-RS burst patterns that span multiple time instances. Instead of measuring channel state at a single moment, the system measurements across multiple time points, adding temporal dimensionality to the CSI measurement process. This dimensional expansion enables more comprehensive channel characterization for high data traffic scenarios without fundamentally redesigning the measurement architecture.

The patent performs preliminary channel and interference measurements across multiple time instances before the actual CSI calculation is needed. By pre-configuring and pre-measuring CSI-RS resources in burst patterns, the system prepares comprehensive channel state data in advance, enabling rapid CSI derivation when required. This preliminary measurement approach ensures reliable multi-time-instance channel characterization while minimizing the time needed for final CSI calculation.

The patent establishes continuous measurement opportunities through periodically repeated CSI-RS burst patterns. Instead of intermittent or single-point measurements, the system maintains continuous measurement action across multiple time instances, ensuring that channel state information is always available from the most recent and relevant time points. This continuous measurement approach improves reliability for low latency communication while the periodic nature allows efficient time management.

The patent designs CSI-RS burst patterns that serve multiple functions simultaneously. Each burst pattern configuration supports both channel measurement and interference measurement, and can be used for various CSI calculation scenarios including single-time-instance and multi-time-instance processing. This multi-functionality allows the system to adapt to different channel conditions and measurement requirements using a unified framework, improving versatility without proportionally increasing complexity through standardized pattern definitions.

The patent enables adaptability to different channel conditions by allowing dynamic adjustment of burst pattern parameters such as the number of time instances, resource allocation, and measurement timing. Instead of requiring completely different system configurations for various scenarios, the system modifies key parameters within the burst pattern framework to optimize for specific channel conditions. This parameter-based adaptation approach improves versatility while keeping the fundamental system structure relatively simple.
