Access point and method for aggregate MPDU (A-MPDU) and power-save multi-poll (PSMP) operation

摘要

Embodiments of wireless devices and methods for aggregate MPDU (A-MPDU) communications in an IEEE 802.11n network are generally described herein. Two or more A-MPDU subframes are aggregated to form an A-MPDU. In some embodiments, an access point (AP) that is configured for power-save multi-poll (PSMP) operation transmits a PSMP burst comprising a PSMP sequence of two or more A-MPDUs to a plurality of mobile stations (STA) during a downlink phase of the PSMP sequence. During PSMP operation, the AP is to receive a PSMP sequence of two or more A-MPDUs from the STAs during an uplink phase of the PSMP sequence.

主权项

1. An apparatus of an access point (AP), the apparatus comprising memory; and
logic circuitry coupled to the memory, the logic circuitry configured to: generate a power-save multi-poll (PSMP) frame as part of a PSMP sequence, the PSMP frame comprising a first mapping; configure aggregated MAC protocol data units (A-MPDUs) for transmission as part of the PSMP sequence, the PSMP sequence configurable to include both group-addressed frames and individually addressed frames to two or more scheduled mobile stations; configure the AP to transmit the A-MPDUs during a downlink phase of the PSMP sequence; decode during an uplink phase of the PSMP sequence, uplink A-MPDUs sequentially from the two or more scheduled mobile stations in accordance with the first mapping, each received uplink A-MPDU including at least an acknowledgement; and configure the AP to transmit a second mapping when an acknowledgement is not received from one or more of the scheduled mobile stations during the uplink phase, the second mapping for the one or more mobile stations for which the acknowledgement was not received.
