Classification: CPC H | IPC H

Claim 14:
15. A receiver configured for message detection in a communication network, the receiver 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 coupled to the preamble detector and configured to generate a trigger signal based on the time delay estimate, wherein the trigger signal indicates when the detected preamble is detected; and
an uplink shared channel receiver coupled to the uplink receiver controller, wherein the uplink shared channel receiver includes a frequency shifter and a channel decoder, wherein the frequency shifter shifts the data samples to generate frequency shifted samples, wherein the channel decoder decodes a user message from the frequency shifted samples in response to the trigger signal, and wherein the frequency shifter is configured to tune a frequency band associated to the uplink shared channel receiver for subsequent receipt of data transmission.
