Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to an open radio access network distributed unit (O-DU) associated with the network node, a grant that permits use of a shared spectrum resource, the grant indicating a first cryptographic checksum for a given timeslot in which the shared spectrum resource is granted. The network node may receive, from the O-DU, a transmission that includes a second cryptographic checksum. The network node may transmit the transmission via the shared spectrum resource based at least in part on an authentication of the transmission, the authentication involving the grant being accepted by the open radio access network radio unit (O-RU) based at least in part on a verification that the second cryptographic checksum corresponds to the first cryptographic checksum. Numerous other aspects are described.

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.

Abstract: Certain aspects of the present disclosure provide techniques for physical resource block allocation alignment. An example method, performed at a first network entity, includes transmitting beamforming weights (BFWs) to a second network entity, each beamforming weight to be applied to a different bundle of one or more physical resource blocks (PRBs), transmitting, to the second network entity, one or more parameters indicative of a misalignment between an allocation of PRBs and at least one logical structure, and processing signals transmitted between the first and second network entities, with beamforming applied to PRB bundles using the BFWs, in accordance with the one or more parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a user equipment (UE), a demodulation reference signal (DMRS) associated with a channel. The RU may perform a channel estimation associated with the channel using the DMRS to obtain channel estimation information. The RU may transmit, to a distributed unit (DU), information that is based at least in part on the channel estimation information. Numerous other aspects are described.

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: 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.
