Abstract: A device and method for providing a mapping of antenna data into antenna containers within a common public radio interface (CPRI) signal exchanged between a radio equipment controller (REC) and at least one radio equipment (RE) are described. The method comprises finding a location of activity within the multiple CPRI basic frames; extracting a candidate antenna signal from the multiple CPRI basic frames starting from the location using a set of mapping parameters used in a standard antenna signal; comparing a candidate frequency content of the candidate antenna signal to a standard frequency content of the standard antenna signal to derive a validity score; associating the set of mapping parameters of the standard antenna signal to the observed mapping if the validity score meets predetermined conditions; and causing a report of the observed mapping.
