Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an open distributed unit (O-DU) may generate a unique group identifier (ID) for each user group of one or more user groups, each user group including a group of user equipments (UEs) that share time-frequency resources in a slot but occupy different spatial layers. The O-DU may transmit one or more messages to an open radio unit (O-RU), each message associated with a respective user group including a group ID for the respective user group. Numerous other aspects are described.

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 slot level configuration information. The control plane message may include a common section header that identifies a group of one or more endpoints, and one or more section type commands that include information associated with a slot level common configuration for the group of one or more endpoints. The RU may perform at least one of radio frequency configuration or time domain beamforming for the group of one or more endpoints based at least in part on the information included in the one or more section type commands. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may transmit, to an open distributed unit (O-DU), a first set of capabilities of the network entity, the first set of capabilities including one or more of at least one O-RU capability or at least one endpoint capability. The network entity may receive, from the O-DU, an indication of one or more features configured by the O-DU. The network entity may select a second set of capabilities of the network entity based at least in part on the one or more features configured by the O-DU. The network entity may transmit, to the O-DU, the second set of capabilities of the network entity. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A remote unit (RU) may transmit, to a distributed unit (DU), an indication of a skew time parameter associated with providing compensated samples for a plurality of symbols associated with a slot. The RU may store a set of samples associated with a first subset of the plurality of symbols associated with the slot, the storing based on a processing delay associated with receiving demodulation reference signals during a portion of the first subset of the plurality of symbols associated with the slot. The RU may transmit, to the DU, a burst of compensated samples for the plurality of symbols in a transmission window that is offset in time from a beginning symbol of the slot according to the skew time parameter.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may transmit, to a controller of the RU, a message including an ordered list of coordinates corresponding to a plurality of antenna elements in an antenna array of the RU. The RU may receive, from the controller, an indication of one or more low-level endpoints associated with one or more activated antenna elements of the plurality of antenna elements. Numerous other aspects are described.

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.
