A method is provided for sending information in a wireless network. A service data unit is broken up by a transmitter into multiple fragments that are sent as the payloads of respective data frames transmitted to a receiver. Each of these frames includes a service data unit identifier identifying the service data unit the fragment is associated with, a fragment number indicating the position of the fragment within the associated service data unit, and a total fragment value indicating the total number of fragments in the service data unit. The receiver extracts the service data unit fragments, buffers them, and uses the fragments to reconstruct the service data unit. The receiver is able to efficiently buffer the fragments because of the service data unit identifier, fragment number, and total fragment value contained in each frame.
