Abstract
A method performed by a STA may comprise transmitting a first negotiation message to an AP and receiving a second negotiation message from the AP. The first negotiation message and the second negotiation message may negotiate a block acknowledgement agreement between the STA and the AP. The method may further comprise receiving a data unit, from the AP, the data unit having a duration field indicating a duration of a block-ACK frame. The duration of the block-ACK frame may be determined based on the negotiated block ACK agreement. A block-ACK frame may be transmitted within the duration indicated by the duration field.
Claims20
A method performed by a station (STA), the method comprising:
- transmitting a first negotiation message to an access point (AP);
- receiving a second negotiation message from the AP, wherein the first negotiation message and the second negotiation message negotiate a block acknowledgement agreement between the STA and the AP;
- receiving a data unit, from the AP, the data unit having a duration field indicating a duration of a block acknowledgement (block-ACK) frame, wherein the duration of the block-ACK frame is based on the negotiated block ACK agreement;
- and
- transmitting a block-ACK frame within the duration indicated by the duration field.
A station (STA) comprising:
- a transceiver configured to transmit a first negotiation message to an access point (AP) and receive a second negotiation message from the AP, wherein the first negotiation message and the second negotiation message negotiate a block acknowledgement agreement between the STA and the AP;
- the transceiver configured to receive a data unit, from the AP, the data unit having a duration field indicating a duration of a block acknowledgement (block-ACK) frame, wherein the duration of the block-ACK frame is based on the negotiated block ACK agreement;
- and
- the transceiver configured to transmit a block-ACK frame within the duration indicated by the duration field.
An access point (AP) comprising:
- a transceiver configured to transmit a first negotiation message to a station (STA) and receive a second negotiation message from the STA, wherein the first negotiation message and the second negotiation message negotiate a block acknowledgement agreement between the STA and the AP;
- the transceiver configured to transmit a data unit, to the STA, the data unit having a duration field indicating a duration of a block acknowledgement (block-ACK) frame, wherein the duration of the block-ACK frame is based on the negotiated block ACK agreement;
- and
- the transceiver configured to receive a block-ACK frame within the duration indicated by the duration field.
