Embodiments disclosed herein relate to preamble configuration in wireless communication systems (e.g., UHDR-DO type systems). Disclosed embodiments disclose receiving a plurality of information bits, generating a plurality of preamble codewords based on a determined a set of monitored MAC_IDs, correlating the information bits with each of the plurality of preamble codewords, determining if a maximum correlation value exceeds a threshold, and transmitting at least one of the preamble codewords if the threshold is exceeded.
