The method includes generating a preamble sequence at a transmitter, where the transmitter is capable of generating a first type of preamble sequence and a second type of preamble sequence. The transmitter transmits a request message to a receiver to request network resources, where the request message including the preamble sequence. The transmitter receives a feedback message from the receiver. The transmitter controls the network data traffic based on the feedback message. The method further includes receiving, a receiver, a signal from the transmitter, the signal including the preamble sequence. The receiver detects the preamble sequence within the signal, where the receiver is capable of detecting a first type of preamble sequence and a second type of preamble sequence. The receiver identifies a request message within the signal based on the detected preamble sequence, and controls the network data traffic based on the identified request message.
