Copy Auto to Manual (LTE)

The Copy Auto to Manual button copies autodetected allocations to manual definitions in the LTE Allocation Editor.

For downlink, when RB Auto Detect Mode is set to Power Based, modulation groups that are present in the signal will be copied to user allocations in increasing order of user number and modulation depth. For example, when QPSK Quadrature phase shift keying and 64QAM modulation groups are present, their contents will be copied to manual user allocations User_01 and User_02, respectively.

When RB Auto Detect Mode is set to Decode PDCCH, the user allocations autodetected from PDCCH Physical Downlink Control Channel will be copied into the LTE Allocation Editor as manual definitions in increasing order of RNTI Radio Network Temporary Identifier.

For uplink, when Copy Auto to Manual is clicked, User_01, which contains all autodetected channels, will be copied into the LTE Allocation Editor.

This button is useful when you have two signals with identical allocations, where one has a fairly good SNR Signal-to-Noise Ratio, but the other has a low SNR. In this case, RB Auto Detect may detect the allocations for the noisy signal incorrectly. To work around this, you could recall the clean signal, autodetect allocations, and click Copy Auto to Manual. Then you could recall the noisy signal and not have to rely on autodetection.

Existing manual user mappings will be overwritten when you click this button.

Although the LTE Long Term Evolution demodulator can analyze more than one frame, only the first full frame of autodetected user allocations will be copied to the manual user mappings when the Measurement Interval is more than 20 slots.

For downlink signals, auto detection supports only PDSCH Physical Downlink Shared Channel allocations transmitted on C-RS Cell-specific RS antenna ports.
