Patent ID: 8239743

Claim:
A method implemented in a user equipment (UE) for transmitting information over a radio interface to a network based on a communications protocol that includes multiple protocol layers, the method comprising: receiving a data unit to be transmitted to the network; determining by the UE error detection bits for the data unit; the UE adding the determined error detection bits for the data unit to generate a new data unit; the UE segmenting the new data unit into segments at a lower protocol layer; and the UE providing the segments for transmission to the network for reassembly into a reassembled data unit where the added error detection bits may be used to determine a transmission error in information in the reassembled data unit, wherein the segments are transmitted using a common uplink radio resource accessible to multiple UEs, and wherein the added error detection bits are useable in the network to determine whether segments received for a reassembled data unit are from a same UE or from different UEs.
