Patent ID: 8654748

Claim:
An access point (AP) configured for power-save multi-poll (PSMP) operation comprising: media-access control (MAC) layer circuitry to aggregate a sequence of two or more medium access control (MAC) protocol data units (MPDUs) to form an aggregate MPDU (A-MPDU); and physical (PHY) layer circuitry to transmit a PSMP burst comprising the A-MPDU in a physical layer convergence procedure (PLCP) service data unit (PSDU) to a plurality of mobile stations (STA) during a downlink phase of a PSMP sequence and to receive a PSMP sequence of two or more A-MPDUs from the STAs during an uplink phase of the PSMP sequence, wherein the MAC layer circuitry is to configure A-MPDUs, wherein each A-MPDU received during the uplink phase includes an acknowledgement (ACK) to acknowledge receipt of an associated one of the A-MPDUs transmitted during the downlink phase, wherein the PHY layer circuitry is further arranged to transmit a plurality of downlink acknowledgements to the mobile stations to acknowledge the A-MPDUs received during the uplink phase of the PSMP sequence, wherein when the AP is functioning as a high-throughput (HT) AP, the MPDUs of the A-MPDU are configurable to have a group-addressed receiver address (RA), and wherein when the AP is not functioning as a high-throughput (HT) AP, the MPDUs of the A-MPDU are configurable to each have a different individual-addressed receiver address (RA) for each of the mobile stations.
