Aggregate MAC service data unit (A-MSDU) and aggregate MAC protocol data unit (A-MPDU) of next generation V2X (NGV) station (STA)

A method for receiving one or more aggregated data frames at a first station (STA) device that are transmitted by a second STA device in a wireless personal area network in accordance with IEEE 802.11bc protocol, comprising:

• receiving and processing, by the first STA device, a first aggregated MAC protocol data unit (A-MPDU) frame that is assembled and transmitted by the second STA device, where the first A-MPDU frame comprises a plurality of A-MPDU subframes characterized by a fixed MPDU start spacing parameter and a fixed maximal MPDU length parameter, where the first and second STA devices are each configured with the fixed MPDU start spacing parameter and the fixed maximal MPDU length parameter, and without negotiating association request and response messages between the first and second STA devices;
• identifying, by the first STA device, one or more of the plurality of A-MPDU subframes in the first A-MPDU frame which are not successfully received by the first STA device;
• and
• assembling and transmitting, by the first STA device, a first block acknowledgement (BA) message comprising a BA bitmap identifying the one or more of the plurality of A-MPDU subframes which are not successfully received by the first STA device, where the BA bitmap has a size characterized by a fixed buffer size parameter which is configured at the first STA device without negotiating add BArequest (ADDBA Request) request and response messages between the first and second STA devices where the first and second STA devices each comprise Next Generation Vehicle-to-Everything (NGV) STA devices.

An apparatus for transmitting one or more aggregated data frames in a wireless personal area network in accordance with IEEE 802.11bc protocol, comprising:

• a transceiver to exchange data with a wireless device;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the apparatus to:
• assemble and transmit a first aggregated MAC protocol data unit (A-MPDU) frame comprising a plurality of A-MPDU subframes characterized by a fixed MPDU start spacing parameter and a fixed maximal MPDU length parameter, where the apparatus is configured with the fixed MPDU start spacing parameter and the fixed maximal MPDU length parameter, and without negotiating association request and response messages with the wireless device;
• and
• receive and process a first block acknowledgement (BA) message that is assembled and transmitted by the wireless device,
• where the BA message comprises a BA bitmap identifying one or more of the plurality of A-MPDU subframes which are not successfully received by the wireless device, and
• where the BA bitmap has a size characterized by a fixed buffer size parameter which is configured at the wireless device without negotiating add BArequest (ADDBA Request) request and response messages with the apparatus where the apparatus and the wireless device are each wireless Next Generation Vehicle-to-Everything (NGV) station (STA) devices.
