Original Abstract Submitted

Techniques related to multi-layer wireless communications are disclosed. Some aspects of the disclosure relate to devices and methods for determining a transmission power boost for a phase-tracking reference signal (PT-RS). A wireless user equipment (UE) may map a multi-layer uplink transmission to a plurality of PT-RS ports by distributing the layers of the multi-layer uplink transmission among the plurality of PT-RS ports. The UE may determine a first transmission power boost for a first PT-RS port, and a second transmission power boost, different from the first transmission power boost, for a second PT-RS port. The UE may transmit a first PT-RS corresponding to the first PT-RS port utilizing the first transmission power boost, and the second PT-RS corresponding to the second PT-RS port, frequency division multiplexed with the first PT-RS, utilizing the second transmission power boost. Other aspects, embodiments, and features are also claimed and described.
