Abstract: Certain aspects of the present disclosure provide techniques for interference management reference signal (RS) transmission. An example method, performed at a first network entity, generally includes applying a frequency domain function to a first copy of a first reference signal (RS) sequence to obtain a modified first copy of the first RS sequence, and outputting, to a second network entity, frequency domain samples of the modified first copy of the first RS sequence and frequency domain samples of a second copy of the first RS sequence.

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.

In some aspects, a radio unit (RU) may provide, to a distributed unit (DU), capability information associated with at least one antenna element set, the at least one antenna element set comprising a set of antenna elements, of a plurality of antenna elements of the RU, configured for communication while the set of antenna elements is active. The RU may obtain, from the DU, a slot level control plane configuration message comprising a radio frequency (RF) channel reconfiguration command that indicates an antenna element set of the at least one antenna element set. The RU may communicate, based on the RF channel reconfiguration command, a wireless communication using the antenna element set. 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.

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: 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.
