Abstract
A system and method for providing messaging between an Open Radio Access Network Distributed Unit (O-DU) and an Open Radio Access Network Radio Unit (O-RU) for on-demand non-delay-managed Demodulation Reference Signal (DMRS) transfer and improving beamforming. An O-DU sending a request message with Demodulation Reference Signal (DMRS) configuration information to an O-RU, and the O-RU extracts non-port-reduced DMRS data and transmits it in a non-delay managed manner to the O-DU. The O-DU identifies one or more users that need an improved update rate of channel state information and triggers the non-port-reduced DMRS transfer based on at least a doppler speed of the user and/or an inter-cell interference level due to user density.
