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: 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.
