PHASE TRACKING REFERENCE SIGNALS (PTRSs) WITH ZERO POWER (ZP) TONES

Abstract:

Aspects of the present disclosure can be implemented in a method for wireless communication by a first wireless node. The method generally includes receiving, from a second wireless node, information regarding PTRS tones, designating one or more of the PTRS tones as ZP tones and one or more of the PTRS tones as NZP tones based, at least in part, on the information, and transmitting a PTRS on the NZP tones. In some cases, the first wireless node is a user equipment (UE) and the second wireless node is a network entity. In some cases, the first wireless node is a network entity and the second wireless node is a UE.
