Abstract
A method of enabling an Open RAN-compatible radio unit (O-RU) to apply different beamforming weights to different physical resource blocks (PRBs) using a single sectionId and a single section extension type includes: specifying a first mode of operation in which flexible sending of beamforming weights from Open RAN-compatible distributed unit (O-DU) to Open RAN-compatible radio unit (O-RU) is provided; and providing, by the O-DU to the O-RU, i) a first parameter specifying the number of bundled physical resource blocks (PRBs) per a set of in-phase/quadrature (I/Q) beamforming weight pairs, each beamforming weight pair comprising an in-phase value and a quadrature value, and ii) a plurality of beamforming weight pairs for a plurality of transceivers associated with each bundle of PRBs. The method provides a new section extension type sent by the O-DU to the O-RU and including a compression parameter for processing or decompressing the beamforming weights.
