 point A 1 The behavior of the beam filters is standardized, and the configuration of the beam filters is provided via RRC signaling. The filtering reporting period at E equals one measurement period at A . E: A measurement (i.e., beam-specific measurement) after processing in the beam filter. The reporting rate is identical to the reporting rate at point A1. This measurement is used as input for selecting the Nbest-beams measurements to be reported. Beam selection for beam reporting: It selects the Nbest-beams measurements from the measurements provided at point E. The behavior of the beam selection is standardized, and the configuration of this module is provided via RRC signaling. F: The beam measurement information included in measurement report sent over the radio interface. Layer 1 filtering introduces a certain level of measurement averaging and the manner through which the UE performs the required measurements is implementation specific to the point that the output at B fulfills the performance requirements. The layer 3 filtering function for cell quality and the related parameters do not introduce any delay in the sample availability at points B and C in Fig. 2.30. The measurements at points C and C1 are the input used in the event evaluation. The L3 beam filtering and the related parameters do not cause any delay in the sample availability at points E and F. The measurement reports are characterized by the following criteria [8]: Measurement reports include the measurement identity of the associated measurement configuration that triggered the reporting. Cell and beam measurement quantities to be included in measurement reports are con- figured by the network. New Radio Access Layer 2/3 Aspects and System Operation 273 The number of non-serving cells to be reported can be limited through configuration by the network. Cells belonging to a blacklist configured by the network are not used in event evalua- tion and reporting, and conversely when a whitelist is configured by the network, only the cells belon
