COEXISTENCE OF PTRS WITH NR REFERENCE SIGNALS - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18020046 Titled 'COEXISTENCE OF PTRS WITH NR REFERENCE SIGNALS'

Simplified Explanation

The abstract describes a method for improving the quality of a wireless signal received by a wireless device. The method involves receiving a wireless signal that includes a phase tracking reference signal (PT-RS) on certain subcarriers. The PT-RS is used to compute a filter that reduces interference between different subcarriers. This filter is then applied to the received signal to improve its quality.

Original Abstract Submitted

According to some embodiments, a method performed by a wireless device comprises receiving a wireless signal R over all subcarriers allocated to the wireless device. The signal R 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 R to generate a de-ICI filtered signal.
