Patent ID: 8432936

Claim:
An apparatus comprising: a transmitter configured to transmit multiplex protocol data units (MUX-PDUs) in a wireless communication system; and a processor coupled to the transmitter and configured with processor-executable instructions to perform operations comprising: generating a plurality of MUX-PDUs for a plurality of media streams, mapping the plurality of MUX-PDUs to a plurality of physical layer (PHYI packets having a predetermined PHY packet size such that each MUX-PDU that conforms to or is smaller than the predetermined PHY packet size is sent in one PHY packet and each MUX-PDU that is larger than the predetermined PHY packet size is sent in a plurality of PHY packets; determining whether one or more null MUX-PDUs can be sent in a remaining space in any of the plurality of PHY packets to which the plurality of MUX-PDUs are mapped; and padding the remaining space with the one or more null MUX-PDUs upon determining the one or more null MUX-PDY can be sent in the remaining space.
