This topic describes the Adjacent Channel Leakage Ratio measurement. Adjacent Channel Leakage Ratio is a measurement in the Dedicated Physical Channel measurement suite.
The Adjacent Channel Leakage Ratio (ACLR) measurement measures the ratio of the RRC Filtered Mean Power centered on the assigned channel frequency to the RRC filtered mean power centered on the adjacent channel frequency. The adjacent channels are located at ±5 MHz and ±10 MHz offsets.
The ACLR measurement is defined in the 3GPP standards in TS 34.121 section 5.10.
Note: This measurement automatically runs the RRC Filtered Mean Power measurement, so there is no need to run the RRC Filtered Mean Power measurement while you are running the ACLR measurement.
Adjacent Channel Leakage Ratio is a measurement in the Dedicated Physical Channel measurement suite. See Dedicated Physical Channel Measurement Suite Measurement Parameters for details of the parameters that apply to measurements in the suite.
Adjacent Channel Leakage Ratio is a measurement in the Dedicated Physical Channel measurement suite. See Dedicated Physical Channel Measurement Suite Measurement Limits for details of the limits parameters that apply to measurements in the suite.
This result provides the integrity indicator for the Dedicated Physical Channel measurement suite. Normal indicates that the measurement suite completed successfully without error and the result is accurate. For details of other integrity indicators, see Measurement Integrity Indicator.
