Abstract: Various examples of embodiments described herein relate to methods and apparatuses for O-RAN Open Fronthaul Section Enhancement. One such example of an embodiment relates to a method that includes providing, through application of the Section Extension 11, SE11, an offset information indicating an offset between a first allocated Physical Resource Block, PRB, among PRBs of a bundle of PRBs and a lower PRB bundle boundary related to a first PRB among the PRBs of the bundle of PRBs, wherein the bundle of PRBs is associated with an endpoint terminal and wherein the first PRB is an allocated or a non-allocated PRB.

Abstract: Disclosed is a method comprising transmitting, by an apparatus, to a distributed unit, information indicating one or more capabilities of the apparatus, wherein the one or more capabilities comprise at least a capability for mitigating an overload of a control plane processing capacity of the apparatus in a slot; and receiving, by the apparatus, from the distributed unit, based on transmitting the information, one or more messages comprising a plurality of control plane sections to be processed in one or more slots.

Abstract: A fronthaul control plane message comprises three or more control plane sections for channels within a resource element range, at least two of which control plane sections are applicable at least in one of resource elements within the resource element range, and the control plane sections comprise or indicate priority information, based on which one of the control plane sections may be selected to be used in a resource element.

Abstract: Disclosed is a method comprising processing a first set of data, assigning the first set of data to a first timing group comprising a first transmission time window, transmitting the first set of data via a fronthaul interface during the first transmission time window, processing a second set of data, wherein at least a part of the second set of data is processed during the first transmission time window, assigning the second set of data to a second timing group comprising a second transmission time window, and transmitting the second set of data via the fronthaul interface during the second transmission time window.

Abstract: A fronthaul control plane message comprises three or more control plane sections for channels within a resource element range, at least two of which control plane sections are applicable at least in one of resource elements within the resource element range, and the control plane sections comprise or indicate priority information, based on which one of the control plane sections may be selected to be used in a resource element.
