1. A method performed by a wireless device, the method comprising:
receiving a wireless signal Rk over all subcarriers allocated to the wireless device, the signal Rk comprising a phase tracking reference signal (PT-RS) on a subset of subcarriers allocated to the wireless device and the subset comprises at least one non-contiguous subcarrier;
computing a de-inter-carrier interference (ICI) filter based on the PT-RS and a channel estimate using a convolutional matrix CR of the received signal Rk; and
applying the de-ICI filter to the received signal Rk to generate a de-ICI filtered signal.
