Classification: CPC H | IPC H

Claim 7:
8. An apparatus for message detection in a communication network, the apparatus comprising:
a preamble detector configured to receive data samples in an uplink transmission from a user equipment and perform preamble detection on the data samples to generate a time delay estimate of a detected preamble;
an uplink receiver controller configured to generate a trigger signal from the time delay estimate, wherein the trigger signal indicates when the detected preamble is detected; and
an uplink shared channel receiver including a frequency shifter that frequency shifts the data samples to generate frequency shifted samples, wherein the uplink shared channel receiver is configured to decode a user message from the data frequency shifted samples in response to the trigger signal, and wherein the user message is received in the uplink transmission after the detected preamble.
