Abstract:
Embodiments for providing frequency offset measurement enhancements are generally described herein. In some embodiments, user equipment is informed of a configuration of a first reference signal and a configuration of a second reference signal. The first reference signal is provided to user equipment for performing channel estimation. A second reference signal for estimating carrier frequency offset is provided, wherein the second reference signal is co-located with the first reference signal. A carrier frequency offset estimation is calculated based on the co-located first and second reference signals.
