Document Type and Number:
WIPO Patent Application WO/2023/206287
Kind Code:
A1
Abstract:
Methods, apparatus, and systems that enable the indication of Demodulation Reference Signal (DMRS) and Phase Tracking Reference Signal (PTRS) for enhancement of the PTRS as well as the DMRS transmissions in future generations of wireless communication systems. In one example aspect, a method for wireless communication includes transmitting, by a base station to a terminal device, a signaling message indicating an association between more than four DMRS ports and at least two PTRS ports. The signaling message includes multiple groups of bits. Each group corresponds to a PTRS port, and each group includes one or more bits indicating a value that corresponds to one of the more than four DMRS ports. The method also includes receiving, by the base station, a transmission from the terminal device according to the signaling message.
