Phase tracking reference signal extension for equalized transmissions

An apparatus configured for wireless communications, comprising:

• a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the apparatus to:
• receive, from a device, one or more capability indications, the one or more capability indications indicating a support for a transmission pre-equalization mode for the device;
• perform a transmission pre-equalization of a message, the transmission pre-equalization performed based on the support for the transmission pre-equalization mode;
• and
• send, to the device, the message comprising one or more phase tracking reference signal (PTRS) pilot signals, the message comprising the one or more PTRS pilot signals based on the one or more capability indications.

A method for wireless communications by an apparatus, comprising:

• sending, to a device, one or more capability indications, the one or more capability indications indicating a support for a transmission pre-equalization mode;
• receiving, from the device, a message comprising one or more phase tracking reference signal (PTRS) pilot signals, the message comprising the one or more PTRS pilot signals based on the one or more capability indications;
• and
• obtaining, from the message, one or more receiver side measurements, the one or more receiver side measurements obtained based on the one or more PTRS pilot signals.
