Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity. The techniques may generally involve generating a message with entries that represent blocks of physical resource blocks (PRBs), for transmitting reference signals over a fronthaul interface using modulation compression; transmitting the message to a second network entity via the fronthaul interface; and processing reference signals, transmitted in the blocks of PRBs on the fronthaul interface using modulation compression.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity. The techniques may generally involve generating a message having a section with entries that represent time and frequency resources for transmitting data and reference signals over a fronthaul interface using modulation compression, transmitting the message to a second network entity via the fronthaul interface, and processing data and reference signal transmissions on the fronthaul interface in accordance with the section.
