Abstract
Certain aspects of the present disclosure provide methods and apparatus for multiuser transmission during a grant to utilize unused portion of a transmit opportunity (TXOP) that is assigned to an initiator device. A responder device may receive, from an initiator device, at least one grant to utilize unused portion of the TXOP. In response to the grant and during the unused portion of the TXOP, The responder device may transmit a first message intended for the to the initiator device, and one or more messages intended for one or more other stations using multi-user transmission schemes. The messages transmitted to stations other than the initiator device may include an indication that the station does not need to respond (e.g., with an acknowledgment) upon receipt of the message.
Claims26
An apparatus for wireless communications, comprising:
- a receiver configured to receive, from a first device, a message comprising at least one grant, wherein the at least one grant grants the apparatus permission to use an unused portion of a transmit opportunity (TXOP) that is assigned to the first device;
- and
- a transmitter configured to transmit, in response to the at least one grant and during the unused portion of the TXOP granted by the at least one grant, at least one first message intended for the first device and at least one second message intended for a second device, wherein the at least one second message comprises an indication that the second device does not need to respond upon receipt of the at least one second message.
A method for wireless communications, comprising:
- receiving, from a first device, a message comprising at least one grant, wherein the at least one grant grants permission to use an unused portion of a transmit opportunity (TXOP) that is assigned to the first device;
- and
- transmitting, in response to the at least one grant and during the unused portion of the TXOP granted by the at least one grant, at least one first message intended for the first device and at least one second message intended for a second device, wherein the at least one second message comprises an indication that the second device does not need to respond upon receipt of the at least one second message.
An apparatus for wireless communications, comprising:
- means for receiving, from a first device, a message comprising at least one grant, wherein the at least one grant grants the apparatus permission to use an unused portion of a transmit opportunity (TXOP) that is assigned to the first device;
- and
- means for transmitting, in response to the at least one grant and during the unused portion of the TXOP granted by the at least one grant, at least one first message intended for the first device and at least one second message intended for a second device, wherein the at least one second message comprises an indication that the second device does not need to respond upon receipt of the at least one second message.
A non-transitory computer-readable medium comprising instructions executable for:
- receiving, from a first device, a message comprising at least one grant, wherein the at least one grant grants permission to use an unused portion of a transmit opportunity (TXOP) that is assigned to the first device;
- and
- transmitting, in response to the at least one grant and during the unused portion of the TXOP granted by the at least one grant, at least one first message intended for the first device and at least one second message intended for a second device, wherein the at least one second message comprises an indication that the second device does not need to respond upon receipt of the at least one second message.
A station for wireless communications, comprising:
- at least one antenna;
- a receiver configured to receive, via the at least one antenna, from a first device, a message comprising at least one grant, wherein the at least one grant grants the station permission to use an unused portion of a transmit opportunity (TXOP) that is assigned to the first device;
- and
- a transmitter configured to transmit, in response to the at least one grant and during the unused portion of the TXOP granted by the at least one grant, at least one first message intended for the first device and at least one second message intended for a second device, wherein the at least one second message comprises an indication that the second device does not need to respond upon receipt of the at least one second message.
