Summary:According to some embodiments, a method performed by a wireless device comprises receiving a wireless signal Rk over all subcarriers allocated to the wireless device. The signal Rk comprises a phase tracking reference signal (PT-RS) on a subset of subcarriers allocated to the wireless device. The method further comprises computing a de-inter-carrier interference (ICI) filter based on a cross correlation of the PT-RS and one or more additional subcarriers and applying the de-ICI filter to the received signal Rk to generate a de-ICI filtered signal.
