The present invention provides a method and system for transmitting and receiving Fragmentable Data Units (FDUs) in a wireless
communication environment. In one embodiment, a method of transmitting FDUs in a wireless communication environment
includes fragmenting a FDU into a fixed number of fragments by a transmitting device. The method further includes packing the
fragments of said FDU in payloads of Medium Access Control (MAC) Protocol Data Units (PDUs). Additionally, the method
includes encoding control information of each fragment of said FDU in a fragmentation control (FC) field and a sequence number
field of the respective MAC PDU. Moreover, the method includes transmitting the MAC PDUs containing the fragments of said
FDU and control information associated with the fragments to a receiving device.
