Base Station Precoding Function Distribution via Interface Bitmap

The patent changes the parameter of information representation by introducing a bitmap structure to indicate precoding function distribution. This transforms the interface signaling from complex textual or structured descriptions into a compact binary parameter format, reducing interface complexity while maintaining flexibility in functional split configurations.

The patent segments the precoding function indication into separate bitmap fields for different precoding types (e.g., Type I, Type II, Type III). This segmentation allows independent control and optimization of each precoding function's distribution between CU and DU, simplifying the overall interface design by breaking down complex functional indications into manageable segments.

The patent transforms precoding function distribution information into compact bitmap parameters, where each bit represents a specific precoding function's location. This parameter transformation reduces the signaling overhead from potentially large structured data to minimal binary representations, enabling efficient optimization of signal transmission without excessive information overhead.

The patent uses bitmap copying mechanisms where the same precoding function indication pattern can be reused across multiple resource blocks or time slots. This copying approach reduces redundant signaling by transmitting the precoding function distribution once and reusing it, thereby optimizing signal transmission efficiency while minimizing information overhead.
