Frequency tracking loop pull-in range extension using frequency error wraparound detection and correction
Abstract:
Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE. The apparatus may measure a frequency error from a first pair of pilot symbols and a second pair of pilot symbols received via a channel associated with communication between the UE and a base station, the measured frequency error from the first pair of pilot symbols and the second pair of pilot symbols corresponding to a first frequency error measurement and a second frequency error measurement. The apparatus may detect a first frequency wraparound in the first frequency error measurement and a second frequency wraparound in the second frequency error measurement. The apparatus may adjust the first frequency error measurement based on the first frequency wraparound or the second frequency error measurement based on the second frequency wraparound if the first frequency wraparound or the second frequency wraparound is the non-zero value.
