Abstract
Some demonstrative embodiments include apparatuses, systems and/or methods of multicast communication. For example, an apparatus may include circuitry configured to cause a wireless device to process transmission of a multicast transmission to a plurality of devices; and to process reception of at least one Multi-User (MU) acknowledgement transmission from two or more devices of the plurality of devices, the MU acknowledgement transmission to acknowledge receipt of the multicast transmission by the two or more devices.
Claims22
An apparatus comprising:
- memory circuitry;
- and
- a processor comprising logic and circuitry configured to cause a wireless communication device to:
- transmit a multicast transmission to a plurality of wireless communication stations (STAs);
- subsequent to the multicast transmission, transmit a first group addressed Multi-User (MU) Block Acknowledgement (BA) trigger frame to two or more first STAs of the plurality of STAs, the first group addressed MU BA trigger frame comprising a group address of a group comprising the two or more first STAs;
- subsequent to the first group addressed MU BA trigger frame, receive one or more first BA frames from one or more respective first STAs of the two or more first STAs;
- subsequent to the one or more first BA frames, transmit a second group addressed MU BA trigger frame to two or more second STAs of the plurality of STAs, the two or more second STAs different from the two or more first STAs;
- and
- receive one or more second BA frames from one or more respective second STAs of the two or more second STAs.
A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause a wireless communication device to:
- transmit a multicast transmission to a plurality of wireless communication stations (STAs);
- subsequent to the multicast transmission, transmit a first group addressed Multi-User (MU) Block Acknowledgement (BA) trigger frame to two or more first STAs of the plurality of STAs, the first group addressed MU BA trigger frame comprising a group address of a group comprising the two or more first STAs;
- subsequent to the first group addressed MU BA trigger frame, receive one or more first BA frames from one or more respective first STAs of the two or more first STAs;
- subsequent to the one or more first BA frames, transmit a second group addressed MU BA trigger frame to two or more second STAs of the plurality of STAs, the two or more second STAs different from the two or more first STAs;
- and
- receive one or more second BA frames from one or more respective second STAs of the two or more second STAs.
An apparatus comprising:
- memory circuitry;
- and
- a processor comprising logic and circuitry configured to cause a wireless communication station (STA) to:
- receive from a wireless communication device a multicast transmission addressed to a plurality of STAs;
- subsequent to the multicast transmission, receive from the wireless communication device a group addressed Multi-User (MU) Block Acknowledgement (BA) trigger frame for two or more STAs of the plurality of STAs, the two or more STAs comprising the STA, the group addressed MU BA trigger frame comprising a group address of a group comprising the two or more STAs, the group addressed MU BA trigger frame to indicate a Resource Unit (RU) allocation of a RU for the STA;
- and
- subsequent to the group addressed MU BA trigger frame, transmit a BA frame to the wireless communication device in the RU for the STA, wherein transmission of the BA frame is in a MU BA transmission simultaneously with another BA frame from another STA of the two or more STAs.
An apparatus for a wireless communication station (STA), the apparatus comprising:
- means for causing the STA to receive from a wireless communication device a multicast transmission addressed to a plurality of STAs;
- means for causing the STA to, subsequent to the multicast transmission, receive from the wireless communication device a group addressed Multi-User (MU) Block Acknowledgement (BA) trigger frame for two or more STAs of the plurality of STAs, the two or more STAs comprising the STA, the group addressed MU BA trigger frame comprising a group address of a group comprising the two or more STAs, the group addressed MU BA trigger frame to indicate a Resource Unit (RU) allocation of a RU for the STA;
- and
- means for causing the STA to, subsequent to the group addressed MU BA trigger frame, transmit a BA frame to the wireless communication device in the RU for the STA, wherein transmission of the BA frame is in a MU BA transmission simultaneously with another BA frame from another STA of the two or more STAs.
