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.

Abstract: Aspects relate to provision of a control message, such as an extension data section, that includes an indication of the repeat of highest priority data sections. The control message may be generated in a distributed unit (DU) and conveyed to a radio unit (RU) via a fronthaul link. The control message may include either a flag or bits in a field of an extension data section allowing a RU to determine repeat of the highest priority data section based on reception of the flag or processing of the bit value in the field. Additionally, the indication of repetition of the highest priority section may be based on a section identifier transmitted by a DU, wherein an RU receiving the section identifier may determine repeat of the highest priority data section by tracking the received section identifier.

Abstract: An attribute is computed based on pixel intensities in an image of the real world, and thereafter used to identify at least one input for processing the image to identify at least a first maximally stable extremal region (MSER) therein. The at least one input is one of (A) a parameter used in MSER processing or (B) a portion of the image to be subject to MSER processing. The attribute may be a variance of pixel intensities, or computed from a histogram of pixel intensities. The attribute may be used with a look-up table, to identify parameter(s) used in MSER processing. The attribute may be a stroke width of a second MSER of a subsampled version of the image. The attribute may be used in checking whether a portion of the image satisfies a predetermined test, and if so including the portion in a region to be subject to MSER processing.

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.
