During Data Resource Bearer (DRB) creation, network signals to a transmitting node, the data transfer requirement. The network uses a signaling parameter to indicate a large data transfer requirement. Based on the data transfer requirement information collected from the network, the transmitting node determines the type of data format that needs to be used for the data transmission. If the network signals large data transfer requirement, then the transmitting node selects a Subheader format in which the length field of the data format suits the large data transfer requirement. Further, data communication is initiated using the selected Subheader format.
