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.

Passthrough of messages in an accelerator of a distributed unit

An Open Radio Access Network Category B radio unit (O-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.

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.

Capability for multiple beamforming codebooks

Apparatus, methods, and computer-readable media for facilitating simplified switching at an RU are disclosed herein. An example method for wireless communication at an RU includes transmitting, to a DU, capability information indicating support of endpoint groups, each endpoint group associated with a respective set of RU endpoints. The example method also includes receiving an eAxC message from the DU based on the capability information, the eAxC message including a DU port identifier, a band sector identifier, a component carrier identifier, and an RU port identifier. The example method also includes using a first portion of the RU port identifier to identify an endpoint group, the respective set of RU endpoints of the endpoint group associated with a set of characteristics. Additionally, the example method includes using a second portion of the RU port identifier to index the eAxC message to an RU endpoint of the endpoint group.

Extended antenna-carrier allocation policy for simplified switching

Managing handover procedures of two or more modems from a serving base station to a target base station includes receiving at least one message indicative of at least one measurement report of radio conditions from at least one modem of the two or more modems; determining, based on the at least one message, whether to handover the two or more modems from the serving base station to the target base station; and upon determining to handover the two or more modems from the serving base station to the target base station, indicating to each of the two or more modems to send to the serving base station a measurement report configured to trigger a respective handover procedure from the serving base station to the target base station.
