Abstract
A dynamic A-MSDU enabling method is disclosed. The method enables the recipient of an aggregate MAC service data unit (A-MSDU) under a block ACK agreement to reject the A-MSDU. The method thus distinguishes between A-MSDU outside of the block ACK agreement, which is mandatory, from A-MSDU under the block ACK agreement, which is optional. The method thus complies with the 802.11n specification while enabling the recipient to intelligently allocate memory during block ACK operations.
Claims6
A station (STA) comprising:
- a buffer;
- a receiver to receive a request that indicates an intent by another station to transmit a number of aggregate medium access controller (MAC) service data units (A-MSDUs) under block acknowledge (ACK) agreements;
- and
- a transmitter to transmit a response frame in response to the request, the response frame to indicate whether or not the station intends to receive the A-MSDUs under block ACK agreements and to indicate that a size of the A-MSDUs to be received under block ACK agreements is supported by the buffer,
- wherein when the station indicates its intention to receive the A-MSDUs under block ACK agreements:
- the receiver is configured to receive the number of A-MSDUs within a MAC protocol data unit (MPDU) under the block ACK agreements after transmission of the response frame;
- and
- the receiver is configured to receive one A-MSDU per block ACK agreement, and
- wherein under the block ACK agreements, the station agrees to confirm that it has received a block of frames comprising the MPDU in response to a block ACK request (BAR) from the other station.
