UE Reference Signal Configuration Across BWPs for Cell Measurement

The patent segments reference signal configuration by bandwidth part, where each BWP is configured with its own reference signal parameters. This allows the system to manage reference signals in a divided manner across different BWPs rather than uniformly across the entire bandwidth, reducing overall management complexity while maintaining comprehensive measurement coverage.

The patent implements dynamic reference signal configuration that adapts to the active BWP state. When a UE switches between BWPs, the reference signal configuration dynamically adjusts to match the current BWP, enabling efficient resource management while ensuring measurements are always performed on appropriate reference signals for the active bandwidth part.

The patent applies local quality by having the UE perform CSI-RS measurements only on the active BWP rather than all BWPs. This localized measurement approach ensures that measurements are performed where they are most relevant (in the currently active bandwidth part) while significantly reducing the total number of measurements required, thereby decreasing processing time and resource consumption.

The patent implements partial action by requiring UEs to measure CSI-RS only in the active BWP rather than performing exhaustive measurements across all configured BWPs. This partial measurement strategy is sufficient for maintaining accurate channel state information for current transmission activities while avoiding the excessive time and resource costs of measuring all possible BWPs.
