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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a distributed unit (DU), a control plane message associated with a section type that is dedicated for information that applies to all resource blocks and spatial layers in a group of carriers or band sectors, wherein the control plane message includes information that applies to all resource blocks and spatial layers in an indicated group of carriers or band sectors. The RU may perform beamforming for one or more communications with a user equipment (UE) based at least in part on the information included in the control plane message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU). The O-DU may communicate with the O-RU using control messaging. The control message may include a resource resource element (RE) mask and a resource symbol mask, the resource RE mask indicating frequency resources to be allocated for a reference signal transmission across a set of antenna ports and the resource symbol mask indicating time resources to be allocated for the reference signal transmission. Additionally or alternatively, the O-DU may transmit a control message including a puncturing resource RE mask indicating frequency resources for applying a puncturing pattern and a symbol mask indicating time resources for applying the puncturing pattern during a transmission.
