Claim 15:
16. A non-transitory computer readable medium storing instructions for managing a cellular network implemented consistent with Open Radio Access Network (O-RAN) standards that, when executed by a processing unit, cause the processing unit to control a process comprising:
receiving from an O-RAN distribution unit (O-DU) a first control-plane message requesting a first set of radio resources responsive to a scheduled uplink transmission from a user device, wherein the first set of radio resources comprises an assigned portion of a carrier signal allocated for the uplink transmission;
generating a second control-plane message requesting a second set of radio resources, wherein the second set of radio resources comprises a remaining portion of the carrier signal not allocated for the uplink transmission;
sending the first control-plane message and the second control-plane message to an O-RAN radio unit (O-RU) configured to receive the uplink transmission from the user device;
receiving from the O-RU at least one user-plane message comprising first digitized data from the uplink transmission correlated with the first control-plane message and second digitized data from the uplink transmission correlated with the second control-plane message;
sending the first digitized data to the O-DU, and not send the second digitized data to the O-DU; and
monitoring the carrier signal for interference sources using both the first digitized data and the second digitized data.
