Title:
APPARATUS AND METHOD FOR PROVIDING DENSITY OF PT-RS
Document Type and Number:
WIPO Patent Application WO/2019/160378
Kind Code:
A1
Abstract:
Provided is a method and apparatus for providing information related to density of a PT-RS in a wireless communication system. The operation method of a base station may include: configuring a phase tracking reference signal (PT-RS) corresponding to a terminal; and transmitting time and frequency density information of the PT-RS to the terminal, and the time and frequency density information of the PT-RS is configured based on threshold values of time and frequency density of the PT-RS which are compressed based on at least one of a uniform sampling grid scheme, a non-uniform sampling grid scheme, a combinational indexing scheme, or a scheme of imposing a limit on a threshold value. Other embodiments may be possible.
