Title:
METHOD AND APPARATUS FOR RECEIVING PTRS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/063466
Kind Code:
A1
Abstract:
The present disclosure describes a method and apparatuses for a UE or a base station to receive a phase tracking reference signal (PTRS) in a wireless communication system. Particularly, the method by which a UE receives a PTRS in a wireless communication system, according to various embodiments of the present disclosure, may comprise the steps of: acquiring a first CFR estimate value in a resource element (RE) to which the PTRS has been allocated, by performing linear interpolation on the basis of two REs to which a demodulation reference signal (DMRS) has been allocated; calculating an estimate value a CPE angle difference for the RE to which the PTRS has been allocated; and on the basis of a second CFR estimate value acquired by applying the estimate value of the CPE angle difference to the first CFR estimate value, performing phase tracking of the RE to which the PTRS has been allocated. Other various embodiments identified by the specification are possible.
