Abstract: A method for determining control and scheduling information of a network includes receiving a radio frequency waveform having scrambled downlink control information (DCI), performing a cell search to determine cell identity information, performing a beam search and beam detection to estimate a signal quality of the waveform, decoding scheduling information associated with the waveform, detecting a control channel encoded with an unknown identity based on the scrambling identity and extracting resource elements of the control channel based on the scheduling information, attempting to decode the control channel via a re-encoding technique that is tested for accuracy and, in response to accuracy testing not passing, via a blind scrambling seed recovery technique, recovering the DCI based on the re-encoding technique or the blind scrambling seed recovery technique, and obtaining the control and scheduling information from the DCI.
