name: CFO
full_form: Carrier Frequency Offset
context: is negligible. - The evaluation results from the source ([75]) show that the impact of the residual CFO on the performance of carrier phase positioning can be mitigated with the use of the double differential technique with a PRU that is located at a fixed location in LOS of the TRP. - The evaluation results from the source [80] show that the impact of residual CFO on carrier phase measurement is negligible. However, carrier phase positioning accuracy degrades significantly with residual CFO with single differential (SD) DL-CPP: - With UE residual CFO 30Hz and TRP residual CFO 10Hz, the accuracy drops from 0.0044m to 0.2m @80% and from 0.0014m to 0.0017m @50% in InF-SH. - With UE residual CFO 100Hz and TRP residual CFO 10Hz, the accuracy drops from 0.0044m to 0.27m @80% and from 0.0014m to 0.0024m @50% in InF-SH. - The evaluation results from the source [86] show that carrier phase positioning accuracy degrades slightly with residual CFO with DD DL-CPP: - With maximum residual CFO
description: Carrier Frequency Offset (CFO) is the difference between the actual and expected frequency of a signal. It is crucial in telecommunications, particularly for New Radio (NR) carrier phase positioning, as it can affect the accuracy of positioning measurements.
explanation: The text explicitly states that CFO is a 'critical network attribute' and a 'parameter influencing network operations'. This classification aligns with the definition of a parameter as a measurable value that affects system performance.
