Abstract
Parsing of C-plane messages is described, e.g., C-plane messages that are communicated from an open RAN distributed unit (O-DU) to an open RAN radio unit (O-RU) in order to determine whether a particular symbol that is to be subsequently communicated via U-plane messages is blank (e.g., no physical resource blocks (PRB)) or not blank (e.g., at least one PRB). A bitmap can be constructed by the O-RU having a bit length equal to the number of symbols to be communicated, where each bit of the bitmap corresponds to one of the symbols. Values of each bit of the bitmap can indicate whether a corresponding symbol is blank or not blank, and, if blank, some devices can be powered down to conserve power on a symbol-by-symbol basis in a manner that is compliant with Open RAN specifications and does not presume the same vendor for O-RU and O-DU.
