Title:
METHOD AND APPARATUS FOR PT-RS MAPPING
Document Type and Number:
WIPO Patent Application WO/2021/087975
Kind Code:
A1
Abstract:
Embodiments of the present disclosure are directed to methods and apparatuses for PT-RS mapping. In an embodiment of the present disclosure, the method includes transmitting a first set of phase-tracking reference signals in a first plurality of subcarriers within a first resource block set associated with a first TCI state with a first frequency density; transmitting a second set of phase-tracking reference signals in a second plurality of subcarriers within a second resource block set associated with a second TCI state with a second frequency density, where the first resource block set and the second resource block set are frequency division multiplexed in a time interval and a third resource block set composed of the first resource block set and the second resource block set is scheduled by a DCI.
