Abstract:
1. A fragmentation state machine in a transmitter, the fragmentation state machine comprising: a fragmentation characterization engine to: generate a header for each fragment of a first service data unit (SDU), the first SDU comprising a plurality of fragments, the first SDU having a flow identifier (ID) indicating a first medium access channel (MAC)/flow connection, the header of each fragment comprising: a first channel ID to indicate a first fragmentation channel through which the fragment of the first SDU is transmitted; a sequence ID indicating a numerical location of the fragment in the first SDU; and a fragmentation extension ID indicating whether the fragment is a first fragment, a last fragment, or a middle fragment of the first SDU, or whether the first SDU is unfragmented; and generate a second header for each fragment of a second SDU, the second SDU comprising a plurality of fragments and the same flow ID as the first SDU, the second header of each fragment of the second SDU comprising: a second channel ID to indicate a second fragmentation channel through which the fragment of the second SDU is transmitted; a sequence ID indicating a relative numerical location of the fragment in the second SDU; and a fragmentation extension ID indicating whether the fragment is a first fragment, a last fragment, or a middle fragment of the second SDU, or whether the second SDU is unfragmented; wherein the fragments of the first and second SDUs are wirelessly transmitted on separate fragmentation channels of the same MAC/flow connection to a receiver.
