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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an open radio access network (O-RAN) distributed unit (O-DU) may generate, at an O-DU application that executes on the O-DU, a first message that does not make use of an O-DU accelerator of the O-DU that is in-line with the O-DU application. The O-DU may transmit, from the O-DU application to an O-RAN radio unit (O-RU), the first message via a passthrough of the O-DU accelerator, wherein the first message does not make use of the O-DU accelerator based at least in part on a payload of the first message being transferred unchanged by the O-DU accelerator to the O-RU. 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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit may output capability information regarding a number of beamforming codebooks supported by the radio unit. The radio unit may obtain configuration information that configures one or more beamforming codebooks for an antenna array of the radio unit. The radio unit may communicate using the one or more beamforming codebooks. Numerous other aspects are described.

Abstract: An Open Radio Access Network Category B radio unit (0-RU) of a wireless network associates, for a first extended antenna carrier identifier (eAxC_Id) corresponding to a layer 0 precoding layer identifier (layerID), the first eAxC_Id with one or more second eAxC_Ids. Each second eAxC_Id corresponds to a non-layer 0 precoding layerID. The O-RU receives, for a user equipment (UE), a control plane message of Section Type 1 or 3. The message includes an extension type (ExtType) 3 first data layer, along with the first eAxC_Id in a transport header. The ExtType 3 first data layer indicates a number of precoding layers. The O-RU then precodes user plane data for downlink physical resource blocks allocated to the UE using the layer 0 precoding layerID of the first eAxC_Id, and each associated non-layer 0 precoding layerID of the one more second eAxC_Ids required to complete the number of precoding layers.
