Abstract
Methods and apparatus for receiving a user message in a communication network are disclosed. In an exemplary embodiment, a method includes receiving data samples in an uplink transmission from user equipment, performing preamble detection on the data samples, generating a trigger signal that indicates when a preamble is detected, and decoding a user message in response to the trigger signal, wherein the user message follows the detected preamble.
Claims20
A method for message detection in a communication network, the method comprising:
- receiving data samples in an uplink transmission from a user equipment;
- performing preamble detection on the data samples to generate an estimated time delay associated with a detected preamble;
- generating a trigger signal based on the estimated time delay when the detected preamble is detected;
- shifting, by a frequency shifter of an uplink shared channel receiver, the data samples to generate frequency shifted samples;
- and
- generating, by a channel decoder of 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.
