Classification: CPC H | IPC H

Claim 16:
17. An apparatus for message detection in a communication network, the apparatus comprising:
a memory; and
a processor coupled to the memory and configured to perform operations of:
receiving data samples in an uplink transmission from a user equipment;
performing preamble detection on the data samples to generate a time delay estimate of a detected preamble;
generating a trigger signal based on the time delay estimate that indicates when the detected preamble is detected;
shifting, by an uplink shared channel receiver, the data samples to generate frequency shifted samples; and
generating, by the uplink shared channel receiver, a user message in response to the frequency shifted samples and the trigger signal, wherein the user message is received via the uplink transmission after the detected preamble.
