Title:
METHODS AND APPARATUSES FOR PHASE TRACKING REFERENCE SIGNAL CONFIGURATION
Document Type and Number:
WIPO Patent Application WO/2019/153195
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses for Phase Tracking Reference Signal (PTRS) configuration. In example embodiments, a method implemented in a network device is provided. According to the method, a set of candidate thresholds associated with at least one of time density, frequency density and group pattern of PTRS to be transmitted between the network device and a terminal device are determined. At least one subset of candidate thresholds are selected from among the set of candidate thresholds. At least one threshold to be used by the terminal device for determining the density of the PTRS is selected from among the at least one subset of candidate thresholds. The network device then transmits an indication of the at least one threshold to the terminal device.
