Patent ID: 7769044

Claim:
A method for transmitting packets from an access point comprising: receiving a plurality of Medium Access Control Service Data Unit packets (MSDUs) in a Medium Access Control unit of the access point, wherein each one of the MSDUs is addressed to at least one of a plurality of receivers in a Basic Service Set of the access point; aggregating the MSDUs into a single Medium Access Control Protocol Data Unit packet (MPDU), wherein aggregating the MSDUs includes: forming a plurality of groups of the MSDUs, wherein each one of the groups of the MSDUs includes all of the MSDUs addressed to a corresponding one of the receivers; including each one of the groups of the MSDUs in corresponding ones of a plurality of subframes, each one of the subframes including a single corresponding subframe header instead of including a respective subframe header for each one of the MSDUs; and including the subframes in the single MPDU, a first one of the MSDUs in a first one of the subframes being addressed to a first one of the receivers, a second one of the MSDUs in a second one of the subframes being addressed to a second one of the receivers, the single MPDU including a single MPDU header instead of a respective MPDU header for each one of the subframes; and transmitting the single MPDU to a Physical layer of the access point for transmission.
