Devices, systems and methods for low latency data transmission in wireless network

A method, comprising:

• by operation of a transmitting device, determining a transmission duration for transmission of data frames to a plurality of different receiving devices, the transmission duration including interframe spacings that separate the data frames from one another;
• by operation of the transmitting device, transmitting a beacon packet for reception by all receiving devices that enables control of the medium by the transmitting device, the beacon packet including medium access parameters for the receiving devices for the transmission duration;
• by operation of the transmitting device, transmitting the data frames over the same medium to each of the plurality of receiving devices, individually and sequentially in time, during the transmission duration without another transmission to reserve the medium for any of the receiving devices;
• wherein
• the data frames transmitted during the transmission duration comprise bursts of multiple, sequential data frames, each burst being addressed to a different receiving device.

A device, comprising:

• memory circuits formed in an integrated circuit (IC) substrate configured to store data frames for transmission to a plurality of receiving devices;
• and
• control circuits formed in the IC substrate and configured to
• determine a transmission duration for the transmission of the data frames to the receiving devices, the transmission duration including at least interframe spacings that separate one data frame transmission from a next data transmission,
• reserve the medium for the transmission duration by transmitting a beacon packet for reception by all receiving devices that enables control of the medium by the device, the beacon packet including medium access parameters for the receiving devices for the transmission duration,
• transmit the data frames over the medium to each receiving device individually and sequentially in time, during the transmission duration and without another transmission to reserve the medium;
• wherein
• the data frames transmitted during the transmission duration comprise bursts of multiple, sequential data frames, each burst being addressed to a different receiving device.

A system, comprising:

• a plurality of receiving devices;
• and
• a controller in communication with the receiving devices over a wireless network, the controller configured to
• arrange data for transmission to the receiving devices into bursts of sequential data frames for each receiving device,
• determine a transmission duration that includes at least the transmission of the data frames and at least interframe spacings between the data frames,
• reserve a medium for the transmission duration by transmitting a beacon packet for reception by all receiving devices, the beacon packet including medium access parameters for the receiving devices for the transmission duration, and
• transmit the data frames over the same medium to each of the receiving devices, individually and sequentially in time, during the transmission duration without another control message to reserve the medium;
• wherein
• the data frames transmitted during the transmission duration comprise bursts of multiple, sequential data frames, each burst being addressed to a different receiving device.
