 Internal layer 1 filtering of the inputs measured at point A. The exact filtering function is implementation specific and the way that the measurements are con- ducted in the physical layer by an implementation (inputs A and layer 1 filtering) in not specified by the standard. Aj The measurements (i.e., beam-specific measurements) reported by layer 1 to layer 3 after layer 1 filtering. Beam consolidation/selection: The beam-specific measurements are consolidated to derive cell quality. The behavior of the beam consolidation/selection is standardized, and the configuration of this module is provided via RRC signaling. The reporting period at B equals one measurement period at A1. B: A measurement (i.e., cell quality) derived from beam-specific measurements reported to layer 3 after beam consolidation/selection. 272 Chapter 2 Layer 3 filtering for cell quality: The filtering performed on the measurements provided at point B. The behavior of the layer 3 filters is standardized and the configuration of the layer 3 filters is provided via RRC signaling. The filtering reporting period at C equals one measurement period at B. C: A measurement after processing in the layer 3 filter. The reporting rate is identical to the reporting rate at point B. This measurement is used as input for one or more evalua- tion of reporting criteria. Evaluation of reporting criteria: It checks whether actual measurement reporting is nec- essary at point D. The evaluation can be based on more than one flow of measurements at reference point C, for example, to compare different measurements. This is illustrated by inputs C and C1. The UE evaluates the reporting criteria at least every time a new measurement result is reported at points C and C1. The reporting criteria are standard- ized, and the configuration is provided via RRC signaling (UE measurements). D: The measurement report information (message) sent on the radio interface. L3 beam filtering: The filtering performed on the measurements (i.e., beam-specific measurements) provided at
